0.98.13:
|
||
|
|
|
||
|
|
SDL: Fixed button configuration when using joystick hats. Thanks to
|
||
|
|
ShaolinMan for pointing out the code errors.
|
||
|
|
|
||
|
|
Readded checks in ines.c for some common bad dumps and non-working hacked
|
||
|
|
games.
|
||
|
|
|
||
|
|
Sprite hit emulation is more precise(as it was in 0.97.5).
|
||
|
|
|
||
|
|
Fixed mapper 185 emulation to work properly with the Japanese
|
||
|
|
version of "Spy vs Spy", and hopefully with the GOOD dump
|
||
|
|
of Banana(I don't think one exists).
|
||
|
|
|
||
|
|
Added per-game hacks for Shougi Meikan '92 and Shougi Meikan '93.
|
||
|
|
|
||
|
|
Fixed a bug in SetupCartMirroring() that could cause some games to have corrupted
|
||
|
|
mirroring if loaded in a certain order. This was a rather major, long-standing
|
||
|
|
bug. :/
|
||
|
|
|
||
|
|
Added many iNES header corrections.
|
||
|
|
|
||
|
|
Fixed emulation of the "ISB" and "DCP" invalid opcodes.
|
||
|
|
|
||
|
|
Optimized the PPU background drawing code with inline assembly. Older/some(?) versions
|
||
|
|
of gcc may produce bad code(from previous experience with inline
|
||
|
|
assembly in gcc), but 3.4.1 seems to do ok.
|
||
|
|
|
||
|
|
Optimized some of the low-quality sound emulation code.
|
||
|
|
|
||
|
|
Added a command-line option to the configure script to enable the FCE Ultra
|
||
|
|
debugger(disabled by default). It reduces executable size, and may increase speed
|
||
|
|
of execution slightly.
|
||
|
|
|
||
|
|
In unix-netplay.c, replaced the ioctl() on a socket to read the number of bytes available to read
|
||
|
|
with a select(). I've also added some "BEOS" #ifdefs. I don't know if they will
|
||
|
|
work properly.
|
||
|
|
|
||
|
|
Replaced archaic include of "malloc.h" in unix-netplay.c with "stdlib.h".
|
||
|
|
Also in unix-netplay.c, I've added:
|
||
|
|
|
||
|
|
#ifndef SOL_TCP
|
||
|
|
#define SOL_TCP IPPROTO_TCP
|
||
|
|
#endif
|
||
|
|
|
||
|
|
Fixed a bug in sdl-sound.c that would prevent FCE Ultra from being compiled
|
||
|
|
on certain platforms(Mac OS X).
|
||
|
|
|
||
|
|
Fixed variable declarations in the following files to be compatible
|
||
|
|
with C compilers that don't adhere to C99(or was it C98...):
|
||
|
|
movie.c
|
||
|
|
drivers/sexyal/convertgen.c and drivers/sexyal/convert.inc
|
||
|
|
drivers/pc/unix-netplay.c
|
||
|
|
|
||
|
|
0.98.12:
|
||
|
|
|
||
|
|
Win32: Fixed the behavior of the sound logging function.
|
||
|
|
|
||
|
|
Fixed a bug that was causing 2xscale/3xscale to be broken
|
||
|
|
when clipping the leftmost and rightmost 8 columns.
|
||
|
|
|
||
|
|
Added an iNES header correction entry for JustBreed.
|
||
|
|
|
||
|
|
Modified the MMC5 "ELROM" board emulation to not emulate WRAM.
|
||
|
|
|
||
|
|
Corrected various pieces of code that were causing compiler warnings.
|
||
|
|
|
||
|
|
Win32: Scaling settings(x, y, stretch to fill screen) are now respected while
|
||
|
|
using a special scaler in full screen mode, though if x or y scale is
|
||
|
|
less than what is needed for a particular scaler, it will be
|
||
|
|
adjusted.
|
||
|
|
|
||
|
|
Win32: The window will be reblitted when it becomes invalidated while
|
||
|
|
a game is loaded(such as when you're resizing the window).
|
||
|
|
|
||
|
|
When the PPU is in a "dead" state after starting up, the graphics
|
||
|
|
buffer is now cleared. Previously, particularly in the Windows port, when
|
||
|
|
a game was closed, and a new game was loaded, the last image from
|
||
|
|
the previous game would be displayed for a short time.
|
||
|
|
|
||
|
|
Win32: Blit skipping will now occur when sound is disabled and FCE Ultra is
|
||
|
|
running behind the desired frame rate.
|
||
|
|
|
||
|
|
Win32: Blit-skipping behavior can now be configured to some extent in the "Timing" configuration
|
||
|
|
window.
|
||
|
|
|
||
|
|
Win32: Added a "Recent Directories" submenu to the "File" menu.
|
||
|
|
|
||
|
|
Removed some debugging code that shouldn't have been enabled in 0.98.11.
|
||
|
|
|
||
|
|
0.98.11:
|
||
|
|
|
||
|
|
Win32: Special scalers are now also supported in windowed mode. For Scale2x/Scale3x,
|
||
|
|
the fastest "desktop" bit depth is 16bpp. For hq2x/hq3x, it is 32bpp.
|
||
|
|
|
||
|
|
The shared video blitting code(drivers/common/vidblit.c) can now blit using Scale2x
|
||
|
|
and Scale3x to any target bit depth(8bpp, 16bpp, 24bpp, and 32bpp) instead of just
|
||
|
|
8bpp, as it was before.
|
||
|
|
HQ2x and HQ3x can now blit to 16bpp, 24bpp(untested), and 32bpp. The 16bpp and
|
||
|
|
24bpp targets are done doing post-processing conversion, after HQ2x/HQ3x, which
|
||
|
|
really does hurt speed.
|
||
|
|
|
||
|
|
Changed a few names in the credits section of the documentation to their
|
||
|
|
aliases. Names you didn't get to pick to have are so troublesome. :b
|
||
|
|
I also made various fixes/updates to the documentation.
|
||
|
|
|
||
|
|
Updated the FAQ with some information regard video mode bit depths and speed.
|
||
|
|
|
||
|
|
SDL: Disabled the fast-forward-key speed-limiting code. I thought I had
|
||
|
|
done this before...
|
||
|
|
|
||
|
|
Fixed a major bug in the movie recording code, and added some code to automatically detect
|
||
|
|
and fix playback of broken movies from earlier versions.
|
||
|
|
|
||
|
|
Did a little swapping thing with mapper 90 and 209. I moved back Mortal Kombat 3
|
||
|
|
to mapper 90, and moved Shin Samurai Spirits 2 to mapper 209. Sorry for any confusion.
|
||
|
|
Mapper 90 should be considered as having the fancy nametable select mode disabled, with
|
||
|
|
mapper 209 having it enabled.
|
||
|
|
|
||
|
|
Added support for mapper 160, which turns out to be the same hardware as mapper
|
||
|
|
90. Joy.
|
||
|
|
|
||
|
|
Improved mapper 90 emulation. This mapper really needs low-level
|
||
|
|
emulation for IRQs to work right, though. :/
|
||
|
|
|
||
|
|
Win32: Fixed the "hide left/right 8 video columns" feature.
|
||
|
|
|
||
|
|
Since FCE Ultra is ending(or has already exceeded? :b) its actively-updated life,
|
||
|
|
I've gone ahead and added per-game hacks for "Kick Master" and the PAL version
|
||
|
|
of "Star Wars". See the documentation for more details.
|
||
|
|
|
||
|
|
Minor optimizations to the high-quality sound emulation code. The FIR filter
|
||
|
|
code is the bottleneck, though, so these changes won't have much of an effect
|
||
|
|
on overall speed.
|
||
|
|
|
||
|
|
Altered MMC3 IRQ emulation(and the hooks in ppu.c for it).
|
||
|
|
|
||
|
|
Fixed a rather major typo in the VRC7-emulation code.
|
||
|
|
|
||
|
|
0.98.10:
|
||
|
|
|
||
|
|
Reimplemented network play. It now requires a standalone network play server, which
|
||
|
|
will be released as a later time. For fun, "starmen.net" is running this server,
|
||
|
|
which is publicly accessible.
|
||
|
|
I also made various code fixes/improvements to allow for network play, particularly
|
||
|
|
with the command handling code.
|
||
|
|
|
||
|
|
Reworked much of the VS Unisystem emulation code, partially based on information from
|
||
|
|
MAME. The following games are now supported:
|
||
|
|
|
||
|
|
Battle City
|
||
|
|
Castlevania
|
||
|
|
Clu Clu Land

|
|
Win32-native: Fixed a bug in the debugger's breakpoint list that appeared when
|
||
|
|
one tried to delete a breakpoint(the control accidentally had auto-sort enabled,
|
||
|
|
causing a discrepancy between what was displayed and what was contained in internal
|
||
|
|
data structures).
|
||
|
|
|
||
|
|
The current disk image XOR original disk image is now stored in save states. This
|
||
|
|
should greatly increase compressability(important for network play), and make
|
||
|
|
it a little more legal to distribute such save states now.
|
||
|
|
|
||
|
|
Modified the save state format to allow for more precise and larger version numbers.
|
||
|
|
|
||
|
|
Various minor code changes.
|
||
|
|
|
||
|
|
Fixed initialization of the FCEUGameInfo structure, which previously led
|
||
|
|
to problems with sound output on the SexyAL-using ports(Linux).
|
||
|
|
|
||
|
|
Apparently I added support for mapper 255 a while back. Documentation updated.
|
||
|
|
|
||
|
|
Added iNES header correction information for Armored Scrum Object and Alpha Mission.
|
||
|
|
|
||
|
|
Merged banksw.h into ines.c, fixed some of its prototypes in ines.h.
|
||
|
|
|
||
|
|
0.98.9:
|
||
|
|
|
||
|
|
Win32-native: Fixed the speed throttling used when sound is disabled. In previous
|
||
|
|
0.98.x Win32-native releases, emulation was running at 1/2 the speed it should
|
||
|
|
have been when sound was disabled.
|
||
|
|
|
||
|
|
Win32-native: Moved settings in the "Miscellaneous" configuration window
|
||
|
|
to where they should have been in the first place, and added "GUI" and "Timing"
|
||
|
|
configuration windows to accommodate some.
|
||
|
|
|
||
|
|
Win32-native: Fixed the handling of the "Scroll Lock" key used to disable and
|
||
|
|
enable Family BASIC Keyboard input.
|
||
|
|
|
||
|
|
Updated documentation to handle some slight differences in the Win32-native
|
||
|
|
port("Win32-native" is what the Win32 port using native APIs, as opposed to something
|
||
|
|
like GTK+ and SDL, will be referred to in documentation now). I also made
|
||
|
|
some other minor wording adjustments to the documentation.
|
||
|
|
|
||
|
|
Added an iNES header correction for Dragonball.
|
||
|
|
|
||
|
|
0.98.8:
|
||
|
|
|
||
|
|
Fixed a typo in sound.c that caused only part of the sound registers
|
||
|
|
to be saved in save states.
|
||
|
|
|
||
|
|
Win32: Switched over to the DirectDraw7 interface, from DirectDraw4's.
|
||
|
|
The surface Flip() method will now block, which results in somewhat
|
||
|
|
smoother animation/scrolling, especially when combined with the
|
||
|
|
auto blit-skip implemented in 0.98.6 when sound is enabled.
|
||
|
|
|
||
|
|
Win32: Undid a change made in the last release that limited the
|
||
|
|
speed of fast-forwarding when using the tilde key. I really do
|
||
|
|
need to implement some sort of unified timing/blit skip system...
|
||
|
|
|
||
|
|
Win32: Added an option, disabled by default, to ask for confirmation
|
||
|
|
before exiting FCE Ultra.
|
||
|
|
|
||
|
|
Win32: Added an option, enabled by default, to disable the system
|
||
|
|
screen saver while a game is loaded.
|
||
|
|
|
||
|
|
Win32: Added a new video synchronization mode, a "lazy" wait for
|
||
|
|
vblank/vertical retrace. It calls Sleep(0) in its wait loop. This
|
||
|
|
still uses all available cpu cycles, but it is much more friendly
|
||
|
|
to other processes than the old-style wait for vblank.
|
||
|
|
|
||
|
|
Win32: Added support for joystick POV hats.
|
||
|
|
|
||
|
|
0.98.7:
|
||
|
|
|
||
|
|
Fixed a bug in the debugger's disassembler when disassembling
|
||
|
|
opcode 0xBC.
|
||
|
|
|
||
|
|
Fixed the behavior of the right mouse button with zapper emulation, to
|
||
|
|
correspond with what it is documented as doing.
|
||
|
|
|
||
|
|
Win32: Added proper support for maximizing the window.
|
||
|
|
|
||
|
|
Win32: Rewrote most of the input and input configuration code.
|
||
|
|
|
||
|
|
Win32: Changed the configurable aspect ratio to something sensical, the current
|
||
|
|
display's pixel aspect ratio, default of 1:1(square pixels).
|
||
|
|
|
||
|
|
Win32: Made the default full-screen video mode the custom video mode. I should have
|
||
|
|
done this a long time ago to make custom video mode configuration more straighforward
|
||
|
|
for users...
|
||
|
|
|
||
|
|
Added some JACK audio code to be used by the SDL build. I'll test it and complete
|
||
|
|
it later.
|
||
|
|
|
||
|
|
0.98.6: Made several code modifications to work with older versions of gcc.
|
||
|
|
|
||
|
|
Fixed more header file network play #ifdef-age.
|
||
|
|
|
||
|
|
Fixed a typo in cart.h.
|
||
|
|
|
||
|
|
Fixed some funky code in FCEU_memmove().
|
||
|
|
|
||
|
|
Fixed some source code causing compiler warnings.
|
||
|
|
|
||
|
|
Fixed SexyAL's format conversion code to not rely on deprecated casting semantics.
|
||
|
|
|
||
|
|
Readded the native Win32 code, and made many improvements. The major thing
|
||
|
|
that needs to be done now with it is to rewrite the input handling code and input
|
||
|
|
configuration code.
|
||
|
|
|
||
|
|
0.98.5:
|
||
|
|
Added LL to the 64-bit integer constants in ines.c
|
||
|
|
|
||
|
|
Fixed OpenGL support under Mac OS X.
|
||
|
|
|
||
|
|
Added the ability to hide background and/or sprites with the F4 key.
|
||
|
|
|
||
|
|
0.98.4:
|
||
|
|
Moved NETWORK #ifdef's to netplay.c to simplify things.
|
||
|
|
|
||
|
|
Fixed gzip file loading code(I think). I'm still a bit unsure about the semantics
|
||
|
|
of dup() and close(), though.
|
||
|
|
|
||
|
|
Corrected FDS code to try loading the FDS image before loading the BIOS.
|
||
|
|
|
||
|
|
Readded "native" SDL sound code, used for Mac OS X(and maybe BeOS).
|
||
|
|
|
||
|
|
0.98.3:
|
||
|
|
Removed the wxWindows GUI code. GTK+ 2 code will take its place,
|
||
|
|
once it is ready.
|
||
|
|
|
||
|
|
Added reset and power commands to the movie format. More commands(such as insert
|
||
|
|
disk, eject disk, flip dip switch, etc.) will be added simultaneously as work
|
||
|
|
on network play continues.
|
||
|
|
|
||
|
|
Modified SexyAL OSS code to not adjust the number of fragments to a power of 2.
|
||
|
|
It works fine on my card, allowing finer-grained buffer size control,
|
||
|
|
but I'm not sure it will work with all chips.
|
||
|
|
|
||
|
|
Fixed parsing of the "-specialfs" command-line argument.
|
||
|
|
|
||
|
|
Added the hq3x scaler.
|
||
|
|
|
||
|
|
Updated to the latest Scale2x code. I also added the Scale3x scaler.
|
||
|
|
|
||
|
|
Changed the keyboard assignments for toggling full screen to "Alt" + "Enter".
|
||
|
|
|
||
|
|
FCEUI_SaveState() and FCEUI_LoadState() changed. Porters should read
|
||
|
|
driver.h.
|
||
|
|
|
||
|
|
Miscellaneous changes to accommodate new network play plan. It's not close
|
||
|
|
to being finished.
|
||
|
|
|
||
|
|
Altered RTI emulation. In Paris Dakar Rally's NMI handler, it does "CLI ; RTI".
|
||
|
|
Previously, FCE Ultra would generate an interrupt right after RTI occured, due to the
|
||
|
|
presumed latency that RTI had with the I flag. I changed it so there is no latency, so
|
||
|
|
no interrupt will occur in this case(interrupts kill this game). The interrupt source
|
||
|
|
is the "frame IRQ", which it never disables, if anyone cares.
|
||
|
|
This change does break the "Stars SE" demo, though. Hmm.
|
||
|
|
|
||
|
|
"FCEUGameInfo" is now a pointer, rather than just a statically-allocated structure.
|
||
|
|
This may cause some null-dereferencing-related crashes, but it should help keep
|
||
|
|
code a little cleaner(maybe?).
|
||
|
|
|
||
|
|
Played around with the FDS FM code some more. It's still not right. Bah.
|
||
|
|
|
||
|
|
Hacked in support for entering Datach/Barcode World barcodes without a GUI, using the
|
||
|
|
F8 key and the numeric keys.
|
||
|
|
|
||
|
|
Added code to save/load movies. Movie support will only record/play back the
|
||
|
|
states of the four emulated gamepads.
|
||
|
|
|
||
|
|
Modified the sound code to use timestamp/timestampbase differently. In addition,
|
||
|
|
timestampbase is now saved in save states("timestamp" doesn't need to be saved, since
|
||
|
|
it's reset to 0 at the end of each emulated frame).
|
||
|
|
|
||
|
|
0.98.2:
|
||
|
|
Fixed a few problems with the SDL command-line build code
|
||
|
|
for Win32. Also, SDL 1.2.7 seems to have a bug that breaks FCE Ultra's
|
||
|
|
full-screen/windowed switching capabilities(at least under Win32).
|
||
|
|
Stupid everything.
|
||
|
|
|
||
|
|
Minor SexyAL changes.
|
||
|
|
|
||
|

Updated documentation.

0.98.1:
|
||
|
|
|
||
|
|
Increased the volume of the FME07 sound channels.
|
||
|
|
|
||
|
|
Fixed a bug in the SexyAL endian conversion code.
|
||
|
|
|
||
|
|
Made the SexyAL chunk conversion loop work.
|
||
|
|
|
||
|
|
Replaced the old OPL2 emulator with a modified version of
|
||
|
|
Mitsutaka Okazaki's YM2413 emulator for the VRC7 sound emulation.
|
||
|
|
|
||
|
|
Decreased the pitch of the FME 07 expansion sound channels by one octave.
|
||
|
|
|
||
|
|
Decreased volume of output of $5011 in MMC5 emulation code.
|
||
|
|
|
||
|
|
|
||
|
|
0.98.0: Some changes I made aren't listed below. Ah well. The magnitude
|
||
|
|
of the changes was too great...
|
||
|
|
|
||
|
|
|
||
|
|
Default sound volume is 100(%), which makes a lot more sense than 75%, but not much.
|
||
|
|
It's multiplied by 3/4 internally now.
|
||
|
|
|
||
|
|
Added support for the Datach barcode reader(GUI interface only). The emulation code
|
||
|
|
was adapted from the VirtuaNES source code.
|
||
|
|
|
||
|
|
Reassigned the Datach games to mapper 157, from 16, with CRC32 checks.
|
||
|
|
|
||
|
|
Increased the maximum number of screen snapshots in the snapshots directory
|
||
|
|
to 99999(from 999).
|
||
|
|
|
||
|
|
Reassigned the following games to mapper 210, using CRC32 checks:
|
||
|
|
Chibi Maruko Chan
|
||
|
|
Dream Master
|
||
|
|
Family Circuit '91
|
||
|
|
Famista '92
|
||
|
|
Famista '93
|
||
|
|
Famista '94
|
||
|
|
Heisei Tensai Bakabon
|
||
|
|
Top Striker
|
||
|
|
Wagyan Land 2
|
||
|
|
Wagyan Land 3
|
||
|
|
If you use a hack/translation of one or more of these games, you will of course
|
||
|
|
need to manually change the mapper number in the header for it to work properly in
|
||
|
|
FCE Ultra. Family Circuit '91 still may not fit in with the rest of these games,
|
||
|
|
but it's definitely not a "stock" mapper 19 setup.
|
||
|
|
|
||
|
|
Fixed an OpenGL palette bug when using scanlines(previously, I think it was
|
||
|
|
setting the palette of the scanlines overlay texture instead of the actual image
|
||
|
|
texture in some instances). The bug showed up on games that make use of the color
|
||
|
|
deemphasis bits.
|
||
|
|
|
||
|
|
Rewrote a lot of the PPU background rendering code to be more accurate(and
|
||
|
|
obfuscated!). This eliminates the X-offset hack I made earlier.
|
||
|
|
|
||
|
|
Removed some of the NSF visualization code, and altered the look of the NSF
|
||
|
|
display slightly. The NSF waveform visualization code will now take into
|
||
|
|
account the current volume setting.
|
||
|
|
|
||
|
|
Changed the default key bindings for the standard emulated gamepad
|
||
|
|
to something more compatible with window managers. I may change it back, but probably
|
||
|
|
not, since it is easily configurable now.
|
||
|
|
|
||
|
|
Updated the MMC5, VRC6, and FME07 low-quality sound emulation code
|
||
|
|
with the compatible parts of the high-quality sound emulation code for those chips.
|
||
|
|
|
||
|
|
Adjusted timing of horizontal scroll update(near the beginning of hblank. I made
|
||
|
|
it occur sooner). I also added a hack to allow X-offset(fine X scroll) changes mid
|
||
|
|
scanline, however, it is extremely ugly, and may not work correctly for everything
|
||
|
|
(doing it correctly would probably kill speed).
|
||
|
|
I mainly did it to fix games like F-1 Race and Mach Rider, and other racing
|
||
|
|
games that are extremely sensitive to horizontal scrolling timing.
|
||
|
|
|
||
|
|
Some FDS IRQ emulation changes to fix some screen corruption problems
|
||
|
|
in "Kaettekita Mario Bros".
|
||
|
|
|
||
|
|
Removed zlib(the code, not support).
|
||
|
|
I also removed support for compiling without zlib(it's small, simple, provides
|
||
|
|
very useful functions, and may provide critical features for fceu in the future).
|
||
|
|
|
||
|
|
*undone, breaks debugger, FIXME.* Replaced some inline functions with macros in x6502.c.
|
||
|
|
|
||
|
|
Increased the speed of Namco 106 sound emulation in HQ sound mode.
|
||
|
|
|
||
|
|
Many many sound emulation changes and adjustments based on blargg's tests.
|
||
|
|
The default sound volume is about 150% what it was before, because the sound range
|
||
|
|
has changed(now -soundvol 100 is like -soundvol 200 on older builds), and the
|
||
|
|
default "soundvol" setting is 75. 100 clips on some Namco games, and 200 clips
|
||
|
|
on many games, so I'll probably have the configurable volume range as [0:125].
|
||
|
|
What exactly is "%" supposed to mean in this case.... 100% of what?!
|
||
|
|
|
||
|
|
When using low-quality sound emulation mode, total emulation speed is about 10%
|
||
|
|
less than previous builds. The change in speed for high-quality sound emulation
|
||
|
|
mode is significantly less.
|
||
|
|
|
||
|
|
Added beginnings of SexyAL to source code tree, removed SDL sound support, and
|
||
|
|
old OSS code.
|
||
|
|
|
||
|
|
Copied over some autoconf/automake stuff from phamicom. It stills needs a bit
|
||
|
|
of work...
|
||
|
|
|
||
|
|
Fixed DMC IRQ emulation. Fixes many CodeMasters games. Finally. ^_^
|
||
|
|
|
||
|
|
Restructured a lot of files, changed the interface between driver and
|
||
|
|
emulator code slightly.
|
||
|
|
|
||
|
|
* Insert stuff here *

November 28, 2003 - Snapshot
|
||
|
|
|
||
|
|
Removed the DOS, Linux SVGAlib, and Win32 targets. *GASP*
|
||
|
|
Win32 support will return(eventually), using SDL + wxWindows.
|
||
|
|
SDL can use svgalib or GGI anyway, so it shouldn't be a huge loss.
|
||
|
|
DOS support will only return if someone ports SDL to DOS. ^_^
|
||
|
|
It would be nice if SDL could accept modelines. Maybe in SDL 2.0...
|
||
|
|
|
||
|
|
Merged fce.c and svga.c into fceu.c, and fce.h and svga.h into fceu.h.
|
||
|
|
|
||
|
|
Reassigned "Mortal Kombat 3 - Special 56 Peoples" to mapper 209.
|
||
|
|
|
||
|
|
Added emulation of the "Oeka Kids" tablet.
|
||
|
|
|
||
|
|
Added emulation of the Family Trainer.
|
||
|
|
|
||
|
|
Added emulation of the "Ultimate Quiz King" buzzers.
|
||
|
|
|
||
|
|
Added emulation of the Mahjong controller.
|
||
|
|
|
||
|
|
Added emulation of HyperShot controllers.
|
||
|
|
|
||
|
|
Fixed loading of NSFs with load addresses below $8000.
|
||
|
|
|
||
|
|
Cleaned and simplified some of the NES APU code.
|
||
|
|
|
||
|
|
Altered mapper 65 emulation. Fixes Kaiketsu Yanchamaru 3. Does it break anything?
|
||
|
|
|
||
|
|
Wrote a small FAQ file.
|
||
|
|
|
||
|
|
Fixed displaying of garbage and other unpleasantness on the first scanline. I need
|
||
|
|
to clean up that code, though.
|
||
|
|
|
||
|
|
Fixed color deemphasis emulation when all bits are set. For some
|
||
|
|
reason, I had commented out the code. Bleh.
|
||
|
|
|
||
|
|
NSF player now writes $C0 to $4017 if the FDS is being used(the FDS
|
||
|
|
BIOS writes $C0 to $4017). $40 for all other NSFs.
|
||
|
|
|
||
|
|
Added support for iNES mapper 58(nnnesterj).
|
||
|
|
|
||
|
|
Added support for iNES mapper 208.
|
||
|
|
|
||
|
|
Reassigned "Fudou Myouou Den" to mapper 207(CRC32 checks).
|
||
|
|
|
||
|
|
Reassigned "Karnov" to mapper 206(CRC32 checks).
|
||
|
|
|
||
|
|
Fixed the mapper 95 code, which was horribly broken.
|
||
|
|
|
||
|
|
Differentiated between mappers 33 and 48. Added CRC checks to assign
|
||
|
|
some games to mapper 48. "Flintstones 2" and "Don Doko Don 2" are
|
||
|
|
the games that need to be assigned to 48. Are there others?
|
||
|
|
|
||
|
|
Replaced usage of TriggerIRQ to X6502_IRQBegin/X6502_IRQEnd combos in
|
||
|
|
various mapper emulation files. 67, 33/48, 40, 73, 42, 65, 6, 182
|
||
|
|
Removed function TriggerIRQ() from x6502.c
|
||
|
|
|
||
|
|
Fixed the sound volume of the VRC7 emulation in high-quality sound mode.
|
||
|
|
Decreased(slightly) the volume of VRC7 emulation in both high-quality sound modes.
|
||
|
|
|
||
|
|
Decreased the volume of the MMC5 expansion sound channels.
|
||
|
|
|
||
|
|
Decreased the volume of the FME-7/mapper 69 expansion sound channels.
|
||
|
|
|
||
|
|
Added FCEU_gmalloc(), which will call exit() if memory allocation fails,
|
||
|
|
otherwise it is guaranteed to return a memory block.
|
||
|
|
This will be used in the mapper code mainly. It should only
|
||
|
|
be used for small memory chunks. The reasoning is that if 64 some like KB of
|
||
|
|
RAM or less can't be allocated, for example, it'd probably be best to
|
||
|
|
exit the emulator ASAP. It also helps to simplify code logic, and
|
||
|
|
help (me) with modularization.
|
||
|
|
The behavior of this may change in the future. I still need to think about it.
|
||
|
|
I should probably save the configuration file regularly(or much better,
|
||
|
|
use the registry) on the Windows port, though.
|
||
|
|
|
||
|
|
Cleaned up the save-state saving/loading code a bit, and added
|
||
|
|
support for linked save state structures for better modularity and
|
||
|
|
less code duplication.
|
||
|
|
|
||
|
|
Merged the iNES and UNIF MMC1, MMC3, and MMC5 code more completely.
|
||
|
|
I may need to sanify CHR RAM and WRAM allocation for pedanticness,
|
||
|
|
though. Also worked on Tengen RAMBO-1 emulation, and mapper 90 emulation.
|
||
|
|
***THIS MAKES SAVE STATES FOR GAMES THAT USE THESE EXPANSION CHIPS INCOMPATIBLE
|
||
|
|
WITH PREVIOUS VERSIONS***
|
||
|
|
I plan on doing the same thing with other mappers/boards in the future, though.
|
||
|
|
Always on the quest for 1.0...
|
||
|
|
|
||
|
|
November 12, 2003 - 0.97.5 Release
|
||
|
|
|
||
|
|
Windows: Added limited support for arguments that change configuration
|
||
|
|
to be passed to FCE Ultra. Example: fceu -pal 1 c:\streetgangs.nes
|
||
|
|
It may be useful in frontends.
|
||
|
|
|
||
|
|
Fixed filename generation for automatic IPS patching when a file
|
||
|
|
with no extension is loaded. Before this change, FCEU would
|
||
|
|
look for "game..ips" with a file named "game".
|
||
|
|
|
||
|
|
Converted and updated the cheat guide in(to) HTML.
|
||
|
|
|
||
|
|
Added support for iNES mappers 202,203,231 from info from cah4e3.
|
||
|
|
Fixed support for mappers 60, 200.
|
||
|
|
|
||
|
|
Fixed various major bugs in the breakpoint deletion code.
|
||
|
|
|
||
|
|
UN*X: Added support for OSS(/dev/dsp) devices that don't support mono
|
||
|
|
sound.
|
||
|
|
|
||
|
|
Increased PPU startup idle time to 2 frames. Fixes that
|
||
|
|
unlicensed "Earthworm Jim 3" game. Does it break anything?
|
||
|
|
|
||
|
|
November 9, 2003 - 0.97.4 Release
|
||
|
|
|
||
|
|
Fixed another obscure PPU emulation screen corruption bug.
|
||
|
|
|
||
|
|
Added support for Game Genie cheats in the cheat interface.
|
||
|
|
|
||
|
|
Windows: Reworked the cheat interface, merging the cheat search
|
||
|
|
and cheat list windows into one.
|
||
|
|
|
||
|
|
Windows: Greatly improved the CPU debugger.
|
||
|
|
The code still needs a lot of cleaning, though.
|
||
|
|
|
||
|
|
Readjusted VRC6 IRQ emulation timing.
|
||
|
|
|
||
|
|
Added support for the UNIF MMC3 board TEROM. The maximum PRG/CHR sizes
|
||
|
|
may not be correct in this implementation, though.
|
||
|
|
|
||
|
|
November 8, 2003 - 0.97.3 Release
|
||
|
|
|
||
|
|
Added a control to set the highest quality sound mode in Windows.
|
||
|
|
This change requires that any users who previously set
|
||
|
|
"high quality sound" to set it again.
|
||
|
|
|
||
|
|
Fixed the volume of high-quality sound mode again. The changes
|
||
|
|
I made earlier didn't affect all the filter coefficients.
|
||
|
|
|
||
|
|
November 8, 2003 - 0.97.2 Release
|
||
|
|
|
||
|
|
Made a minor optimization to writes to palette memory.
|
||
|
|
|
||
|
|
Altered VRC6 IRQ emulation timing slightly.
|
||
|
|
|
||
|
|
Fixed a weirdo PPU emulation bug that could cause garbage on the right
|
||
|
|
side of the screen in certain situations. Thanks to FrenziedPanda for
|
||
|
|
bugging me enough to make me look into the problem and fix it.
|
||
|
|
I should be on the lookout to see if the fix breaks anything, though.
|
||
|
|
|
||
|
|
Fixed the volume of high-quality sound mode(-soundq 1). It was
|
||
|
|
at 1/4 the volume it should have been. I compensated by increasing
|
||
|
|
the precision of the filter coefficients, which increased the sound
|
||
|
|
quality of that mode slightly without hurting performance.
|
||
|
|
|
||
|
|
November 7, 2003 - 0.97.1 Release
|
||
|
|
|
||
|
|
Fixed mapper 105 emulation. I had begun merging it into the
|
||
|
|
rest of the MMC1 code for 0.97, but I hadn't finished it.
|
||
|
|
|
||
|
|
Changed things like RdMem(_PC++); to RdMem(_PC); _PC++;
|
||
|
|
Darn evil global variables. I need to fix them. Screw speed.
|
||
|
|
|
||
|
|
Expanded checks for the global variable "fceuindbg"(used in debug
|
||
|
|
mode to prevent reads in the debugger from altering any registers).
|
||
|
|
|
||
|
|
November 6, 2003 - 0.97 Release
|
||
|
|
* Note: I still had much more I had wanted to get done for 0.97,
|
||
|
|
but I lost even more interest. The Windows port still doesn't
|
||
|
|
have a way to enable the "highest" sound emulation mode, nor the
|
||
|
|
low pass filter code, not to mention that the lowpass filter code
|
||
|
|
isn't complete(I would need to design a high-order FIR filter from an IIR
|
||
|
|
filter to work properly-have the correct rolloff, among other
|
||
|
|
things-at finite playback rates).
|
||
|
|
|
||
|
|
Fixed a bug in the IPS patcher. The recorded size wasn't being updated
|
||
|
|
after a successful realloc() was made, which could lead to corrupted patch
|
||
|
|
data from some patches.
|
||
|
|
|
||
|
|
Added support for mappers 200, 201 from submitted code.
|
||
|
|
|
||
|
|
Rewrote mapper 15 support to make more sense(well, depending
|
||
|
|
on your point of view...).
|
||
|
|
|
||
|
|
Fixed 256KB CHR select support for mapper 115.
|
||
|
|
|
||
|
|
Added support for mapper 12 from code from cah4e3.
|
||
|
|
|
||
|
|
October 16, 2003 - Snapshot
|
||
|
|
|
||
|
|
Fixed support for mapper 245(for nonencrypted/non-smynes-screwed up
|
||
|
|
ROM images only. Fixes "Yong Zhe Dou E Long [...] Dragon Quest 7".
|
||
|
|
|
||
|
|
Added support for mappers 60, 62, 230, 244 from submitted code.
|
||
|
|
|
||
|
|
Modified mapper 90 emulation to allow game-select on reset
|
||
|
|
for "Final Fight 3".
|
||
|
|
|
||
|
|
Modified mapper 45 emulation to allow "Super 8-in-1" to work.
|
||
|
|
|
||
|
|
Added a low-pass filter, and an option to enable it(CLI ports).
|
||
|
|
|
||
|
|
0x00 is now written to $4011 in the NSF player code instead of 0x40.
|
||
|
|
Fixed some other similar sound register init problems that I had fixed
|
||
|
|
in Festalon but forgot to fix in FCEU. Grrr.
|
||
|
|
|
||
|
|
Removed some unnecessary 64-bit integer usage from FIR sound filtering
|
||
|
|
code.
|
||
|
|
|
||
|
|
Added a new sound quality mode. Higher than high, it's highest(in
|
||
|
|
FCE Ultra, for now). Still need to fix the interface to allow
|
||
|
|
enabling it in the Windows port.
|
||
|
|
|
||
|
|
Added some code for lower-level MMC3 IRQ emulation. It isn't completed
|
||
|
|
, and will not work properly as-is. I'm still playing around with
|
||
|
|
it occasionally.
|
||
|
|
|
||
|
|
Fixed the sprite overflow flag(I think I fixed it), that was broken in an earlier
|
||
|
|
pre-0.97 release.
|
||
|
|
|
||
|
|
Fixed support for iNES mapper 193.
|
||
|
|
|
||
|
|
Command line arguments "-pal" and "-gg" now take extra arguments(1/0)
|
||
|
|
and are remembered in the configuration file.
|
||
|
|
|
||
|
|
September 27, 2003 - Snapshot
|
||
|
|
|
||
|
|
Added support for iNES mapper 50.
|
||
|
|
|
||
|
|
Modified the UNIF board initialization code. Hopefully, this
|
||
|
|
new interface will eventually be used with the iNES code.
|
||
|
|
|
||
|
|
Miscellaneous code cleanups.
|
||
|
|
|
||
|
|
/dev/dsp is now set to 8(previously 9) buffers of 128 samples in length
|
||
|
|
in the SDL code.
|
||
|
|
|
||
|
|
Tried to make the save state code more expandable and modular.
|
||
|
|
|
||
|
|
Moved a lot of the PPU code into ppu.c.
|
||
|
|
|
||
|
|
Added more extensive debugging code to the 6502 emulator, to allow
|
||
|
|
for memory read/write hooks(including zero page addressing modes).
|
||
|
|
|
||
|
|
Readadjusted DMC timings when PAL emulation is enabled. It looks
|
||
|
|
like it was correct before I had made the August 2 change. Thanks
|
||
|
|
to Bananmos for the information. I think. :/
|
||
|
|
|
||
|
|
Added support for iNES mapper 193 from information from virtuanes.
|
||
|
|
I think my dump of it is "bad", though. PRG and CHR pages look
|
||
|
|
like they are in the wrong order(logical vs physical? Who's to say
|
||
|
|
what's physical?).
|

September 1, 2003 - Snapshot
|
||
|
|
|
||
|
|
Fixed some minor initialization issues with iNES mappers 7 and 34.
|
||
|
|
|
||
|
|
Added support for UNIF board NES-GNROM.
|
||
|
|
|
||
|
|
Removed support for save states created with versions of FCE Ultra
|
||
|
|
less than 0.56.
|
||
|
|
|
||
|
|
Replaced SDL sound buffering code with a lock-free FIFO implementation
|
||
|
|
written by David Olofson, with a few modifications by myself.
|
||
|
|
|
||
|
|
Fixed a VRC7 NSF bug(it showed up under the reworked driver/file
|
||
|
|
loading order in the cli code).
|
||
|
|
|
||
|
|
The board in "Rolling Thunder" has "RAMBO 1" on it, not "RAMBO-1".
|
||
|
|
|
||
|
|
August 9, 2003 - Snapshot
|
||
|
|
|
||
|
|
Removed the old plain text documentation and replaced it with
|
||
|
|
a new document in HTML. It is not completed yet, though.
|
||
|
|
|
||
|
|
Rewrote the SDL-native audio code to be less wacky and more
|
||
|
|
thread-safe(hopefully). I'm still waiting for a new SDL audio
|
||
|
|
API...
|
||
|
|
|
||
|
|
Altered the MMC5 IRQ timing. Fixes minor graphical glitches
|
||
|
|
in Castlevania 3. Does it break anything?
|
||
|
|
|
||
|
|
Removed some debugging code that got into the last snapshot.
|
||
|
|
|
||
|
|
August 5, 2003 - Snapshot
|
||
|
|
|
||
|
|
Added some code in the IPS patcher to allow for expanding the size of files.
|
||
|
|
|
||
|
|
Fixed a double free() bug with a mapper 51 game(in ines.c).
|
||
|
|
|
||
|
|
Added support for "Alien Syndrome" (US release) as iNES mapper 158.
|
||
|
|
It looks like a derivative of the normal RAMBO-1 board(or is that
|
||
|
|
the name of the chip?), similar to TKSROM/TLSROM(mapper 118).
|
||
|
|
|
||
|
|
Improved the "native" SDL sound code. It will now call SDL_Delay(),
|
||
|
|
among other nice things. The code could probably be improved more,
|
||
|
|
though.
|
||
|
|
|
||
|
|
Added support for decimal components in xscale/yscale in the SDL
|
||
|
|
port. Set the default xscale for windowed mode to 2.40(to get a
|
||
|
|
more correct aspect ratio, assuming the display is currently at
|
||
|
|
a 4:3 aspect ratio).
|
||
|
|
|
||
|
|
Modified args.c to handle floating-point numbers.
|
||
|
|
|
||
|
|
August 2, 2003 - Snapshot.
|
||
|
|
|
||
|
|
Disabled texture wrapping with OpenGL(there were problems at the edges
|
||
|
|
of the screen with linear interpolation). Bah. Now the edges
|
||
|
|
are too bright...
|
||
|
|
|
||
|
|
Improved the accuracy of the DMC timing when PAL emulation is enabled.
|
||
|
|
I still don't think it's totally correct, though.
|
||
|
|
|
||
|
|
Changed the default settings for the SDL code. Full screen
|
||
|
|
is now 640x480x8bpp by default, xscale and yscale are 2 for both full
|
||
|
|
screen and windowed, opengl support is enabled, linear interpolation
|
||
|
|
for OpenGL is enabled, and X-axis stretching is
|
||
|
|
enabled(in full screen).
|
||
|
|
|
||
|
|
"Scanlines" were enabled in 8bpp to 8bpp blits in
|
||
|
|
drivers/common/vidblit.c when they shouldn't have been. Fixed.
|
||
|
|
|
||
|
|
Fixed OpenGL code under big-endian platforms.
|
||
|
|
|
||
|
|
August 1, 2003 - Snapshot.
|
||
|
|
|
||
|
|
Various code clean-ups.
|
||
|
|
|
||
|
|
Played around with adding a GTK+ GUI to the SDL code.
|
||
|
|
|
||
|
|
Rewrote part of the hq sound rectangle wave code.
|
||
|
|
|
||
|
|
Replaced the high-quality sound inline assembly filter code with
|
||
|
|
slightly faster C code.
|
||
|
|
|
||
|
|
Hacked around with GP32 support. I don't know if the GP32 would
|
||
|
|
be fast enough, though.
|
||
|
|
|
||
|
|
Skipped frames will now have D5 of $2002 set at the beginning
|
||
|
|
of the frame. Fixes "Bee 52". I must see if it breaks anything.
|
||
|
|
|
||
|
|
Added OpenGL support to the SDL code.
|
||
|
|
|
||
|
|
Removed the PPU drawing inline assembly code, replacing it with a faster
|
||
|
|
algorithm written in C.
|
||
|
|
|
||
|
|
"Disabling" the 8-sprite limitation will no longer cause
|
||
|
|
"Bee 52" to break. However, the "Solstice" wizard will still
|
||
|
|
have the weird thing growing out of his face in the introduction,
|
||
|
|
since it depends on no more sprites to be rendered.
|
||
|
|
|
||
|
|
Added entry for that Black Bass game for header corrections in
|
||
|
|
ines.c
|
||
|
|
|
||
|
|
Strip color burst bit(D0 of $2001) is only "emulated" if bg or
|
||
|
|
sprite rendering are turned on, at the end of the scanline.
|
||
|
|
Doing it with pixel/tile granularity would require modifying
|
||
|
|
the sprite graphics data copying routine, which I don't
|
||
|
|
feel like doing. Fixes that crazy Sayoonara demo by Chris Covell.
|
||
|
|
I also modified the NES RAM initialization code.
|
||
|
|
|
||
|
|
Adjusted VRC7 IRQ emulation for better Lagrange Point goodness.
|
||
|
|
|
||
|
|
Added support for iNES mapper 91. (VirtuaNES)
|
||
|
|
|
||
|
|
0.96:
|
||
|
|
Improved RAMBO-1(mapper 64) emulation. "Skull and Crossbones" is
|
||
|
|
now playable.
|
||
|
|
|
||
|
|
0.95:
|
||
|
|
|
||
|
|
timestamp and timestampbase are no longer saved/loaded to/from
|
||
|
|
save states. They were causing too many problems I didn't
|
||
|
|
want to fix, and I never intended them to be saved in save states
|
||
|
|
when I wrote the code that uses them.
|
||
|
|
I think the reason they were being saved was that I wanted to make it
|
||
|
|
possible to add movie support and network play save state loading
|
||
|
|
(distributing the save state over the network). So if someone in
|
||
|
|
the future wants to add these features, the issues(primarily with
|
||
|
|
zapper emulation and sound emulation) with saving the time stamp will
|
||
|
|
need to be resolved.
|
||
|
|
|
||
|
|
Fixed some crashing bugs when save states are loaded when
|
||
|
|
high-quality sound emulation is enabled. It is like patching
|
||
|
|
holes in a swiss-cheese boat. All the holes may be patched, but
|
||
|
|
it looks ugly. At least it tastes good...
|
||
|
|
TODO: Look into saving more data in the save states, especially
|
||
|
|
data that is based off of "timestamp" and "timestampbase". Also
|
||
|
|
look into validating this data. Right now, corrupt save state data
|
||
|
|
might cause memory corruption in FCE Ultra.
|
||
|
|
|
||
|
|
Fixed some bugs in the NSF player.
|
||
|
|
|
||
|
|
Cleaned up more code.
|
||
|
|
|
||
|
|
Reduced the usage of TriggerIRQ().
|
||
|
|
|
||
|
|
Split the palette code into a new file, palette.c, from svga.c
|
||
|
|
|
||
|
|
Low-G-Man(NTSC and PAL versions) are now recognized by CRC32 value,
|
||
|
|
and WRAM will be disabled if they are loaded. A warning/status message
|
||
|
|
will also be printed regarding this issue.
|
||
|
|
|
||
|
|
Decreased the volume of the DMC/PCM channel in low-quality sound
|
||
|
|
emulation.
|
||
|
|
|
||
|
|
Low-quality sound emulation now uses 32-bit integers for much
|
||
|
|
better speed.
|
||
|
|
|
||
|
|
FCEUI_CRC32() wasn't returning anything. D'oh. Fixed.
|
||
|
|
|
||
|
|
Added somewhat crude support for games that switch background CHR data
|
||
|
|
mid-scanline (this is needed in games such as Mother, Pirates!,
|
||
|
|
Business Wars, and Marble Madness).
|
||
|
|
|
||
|
|
Altered NMI, IRQ, and BRK emulation again. Fixes some games,
|
||
|
|
like Bases Loaded 2 and Dynamite Bowling, and maybe some others.
|
||
|
|
I had to increase the size of the IRQlow variable for delayed
|
||
|
|
NMI execution... I also had to add a delay between PPU reset
|
||
|
|
and the PPU actually doing anything, to fix "Knight Rider".
|
||
|
|
|
||
|
|
Fixed a mapper 90 save state bug.
|
||
|
|
|
||
|
|
/dev/dsp code now searches for /dev/dsp before /dev/dspX (where X is
|
||
|
|
a non-negative integer).
|
||
|
|
|
||
|
|
SDL joystick axes configuration is now done from the joystick.
|
||
|
|
|
||
|
|
Tweaked various Konami mappers' IRQ counter emulation.
|
||
|
|
|
||
|
|
Added custom SDL throttle code that gives up time slices instead of
|
||
|
|
using 100% cpu.
|
||
|
|
|
||
|
|
Fixed an issue with sprite priorities on MSB-first platforms.
|
||
|
|
|
||
|
|
Modified powerpad.c to avoid a symbol conflict when compiling on the
|
||
|
|
Power PC architecture.
|
||
|
|
|
||
|
|
0.94r3:
|
||
|
|
sound.c:
|
||
|
|
Fixed a divide-by-zero bug that occurred when a virtual
|
||
|
|
reset(like by pressing F10) occurred when sound emulation was
|
||
|
|
disabled.
|
||
|
|
|
||
|
|
0.94r2:
|
||
|
|
drivers/common/vidblit.c:
|
||
|
|
Fixed code for 32bpp blur effect.
|
||
|
|
|
||
|
|
drivers/cli/sdl-video.c:
|
||
|
|
Added error message for unsupported bit depths.
|
||
|
|
|
||
|
|
mappers/simple.c, ines.c:
|
||
|
|
Used this bug fix pseudo-release as an excuse to add
|
||
|
|
support for mapper 107. Information taken from virtuanes.
|
||
|
|
|
||
|
|
0.94(fixed release)
|
||
|
|
---
|
||
|
|
Fixed call to InitUNIXDSPSound in svgalib.c
|
||
|
|
|
||
|
|
Added man pages.
|
||
|
|
|
||
|
|
0.94
|
||
|
|
---
|
||
|
|
Added support for rapid fire A/B buttons on physical joysticks
|
||
|
|
in SDL/svgalib/DOS code.
|
||
|
|
|
||
|
|
Implemented "high-quality" Namco 106 emulation(used for hq sound mode).
|
||
|
|
In this case, "high-quality" means sounding more like it should,
|
||
|
|
not necessarily cleaner. I'm not certain that it's totally correct,
|
||
|
|
but it's in the right direction.
|
||
|
|
|
||
|
|
RAM cheats should no longer affect Game Genie emulation. I still
|
||
|
|
need to completely verify this. There may be some sort of race
|
||
|
|
condition.
|
||
|
|
|
||
|
|
Removed various minor speed hacks in the name of style and
|
||
|
|
correctness(and to make maintaining FCE Ultra easier for those
|
||
|
|
people who are not me). :)
|
||
|
|
|
||
|
|
Removed NSF cpu hacks, as I changed code to make them unnecessary.
|
||
|
|
|
||
|
|
Fixed another FDS IRQ emulation bug. "Famicom Grand Prix II" works
|
||
|
|
now.
|
||
|
|
|
||
|
|
Fixed a memory leak and a heap corruption bug in "file.c".
|
||
|
|
|
||
|
|
Added support for on-the-fly IPS patching.
|
||
|
|
Place the IPS file in the same directory as the file to load,
|
||
|
|
and name it filename.ips.
|
||
|
|
|
||
|
|
Examples: Boat.nes - Boat.nes.ips
|
||
|
|
Boat.zip - Boat.zip.ips
|
||
|
|
Boat.nes.gz - Boat.nes.gz.ips
|
||
|
|
Boat - Boat.ips
|
||
|
|
|
||
|
|
Some operating systems and environments will hide file extensions.
|
||
|
|
Keep this in mind if you are having trouble.
|
||
|
|
|
||
|
|
Patching is supported for all supported formats(iNES, FDS, UNIF, and
|
||
|
|
NSF), but it will probably only be useful for the iNES format. It
|
||
|
|
can be used with the FDS format, but be warned that it will permanently
|
||
|
|
patch your disk image, as the disk image is written back to disk
|
||
|
|
when the game is unloaded(unless the disk image is in a zip file, in
|
||
|
|
which case it isn't written back to disk). UNIF files can't be
|
||
|
|
patched well with the IPS format because they are chunk-based with no
|
||
|
|
fixed offsets. Support for a UNIF patching format may be added
|
||
|
|
in the future(probably by someone else.).
|
||
|
|
|
||
|
|
Added more games to the list in ines.c for having battery-backed
|
||
|
|
WRAM, for header corrections.
|
||
|
|
|
||
|
|
Copied over the 96KHz filter coefficients from Festalon that I forgot
|
||
|
|
to do in 0.92. Oops.
|
||
|
|
|
||
|
|
|
||
|
|
0.93
|
||
|
|
---
|
||
|
|
|
||
|
|
Reduced the volume of the FDS sound channel.
|
||
|
|
|
||
|
|
Fixed a bug in the FDS IRQ emulation code that caused "Lutter" to not work.
|
||
|
|
|
||
|
|
Fixed a bug in unif.c that would cause a crash if a unif file were
|
||
|
|
loaded without a board name being specified(as could happen
|
||
|
|
with a corrupted nsf).
|
||
|
|
|
||
|
|
Fixed a bug in general.c relating to relative filenames(running
|
||
|
|
fce ultra like "./fceu ../big.nes" would work, but "./fceu ../big"
|
||
|
|
would not work- it crashed).
|
||
|
|
|
||

|
|
||
|
|

|
||
|
|
|
||
|
|
Removed NSF player background, and added some special effects goodies.
|
||
|
|
|
||
|
|
Changed the NSF player to use the emulated gamepad as input instead
|
||
|
|
of having special NSF-player-only keys.
|
||
|
|
|
||
|
|
Added support for mapper 249(using nonencrypted games), thanks to SARO
|
||
|
|
for info. SMYNES sucks.
|
||
|
|
|
||
|
|
Updated video blitting library-thing(vidblit.c) with more special
|
||
|
|
effects, and removed 24bpp support.
|
||
|
|
|
||
|
|
SDL cleanupification.
|
||
|
|
|
||
|
|
Added support for mapper 61.
|
||
|
|
|
||
|
|
nnnesterj: Added support for mapper 57.
|
||
|
|
|
||
|
|
Fixed mapper number for "Golden Game 150 in 1". Changed it to 235
|
||
|
|
from 43.
|
||
|
|
|
||
|
|
DDraw back buffer surfaces are now created in system memory if the
|
||
|
|
hardware blitter can't do stretching.
|
||
|
|
|
||
|
|
Restructured file wrapping code.
|
||
|
|
|
||
|
|
Added new cheat search methods.
|
||
|
|
|
||
|
|
Fixed a major cheat unloading memory bug(and memory leak).
|
||
|
|
|
||
|
|
Emulated that funky nonlinear DAC effect for hi-quality sound.
|
||
|
|
|
||
|
|
More fixes/cleanups to FDS emulation code.
|
||
|
|
|
||
|
|
Tweaked PPU timing a bit.
|
||
|
|
|
||
|
|
Improved network play.
|
||
|
|
|
||
|
|
Holding the enter key down will no longer do fun stuff to the nsf
|
||
|
|
player.
|
||
|
|
|
||
|
|
Improved NSF player. It should support streaming pcm nsfs now...
|
||
|
|
|
||
|
|
Changed FDS keyboard keys around a bit. F6 is the disk select key,
|
||
|
|
and F8 is the disk insert/eject key.
|
||
|
|
F8 to insert VS Unisystem coin, F6 to view/toggle dip switches.
|
||
|
|
Hopefully people won't complain after blindly hitting the save state
|
||
|
|
buttons. :)
|
||
|
|
|
||
|
|
Many fixes and improvements to the Windows port. No more cpu-consuming
|
||
|
|
wait loops(specifically, sound). Added a message window.
|
||
|
|
|
||
|
|
FDS sound emulation improvements.
|
||
|
|
|
||
|
|
FDS disks are now auto-inserted on power on(or was it loading a new
|
||
|
|
game...).
|
||
|
|
|
||
|
|
Changed the default last rendered scanline to 231.
|
||
|
|
|
||
|
|
ines header corrections are now printed as status messages, not errors.
|
||
|
|
|
||
|
|
Rearranged input updating code.
|
||
|
|
|
||
|
|
Fixed a sprite transfer bug. Fixes PAL version of Rainbow Islands.
|
||
|
|
|
||
|
|
Debugger hooks added.
|
||
|
|
|
||
|
|
Small optimizations in Refreshline and FetchSpriteData to hopefully
|
||
|
|
offset the slight slowdown in the cpu core.
|
||
|
|
|
||
|
|
MapperHBIRQHook is now called differently(depending on hi/low bg/spr
|
||
|
|
addresses).
|
||
|
|
|
||
|
|
Added support for unif board UNL-8237.
|
||
|
|
|
||
|
|
Added support for mapper 144(death race).
|
||
|
|
|
||
|
|
Added partial support for mapper 74.
|
||
|
|
|
||
|
|
Fixed a cpu emulation bug in GETIYWR. It would sometimes set "target"
|
||
|
|
to 0x10000, which was a BAD THING(overflow; now it wraps).
|
||
|
|
|
||
|
|
Tried to add support for mapper 241. Needs special keyboard emulation.
|
||
|
|
I think.
|
||
|
|
|
||
|
|
Internal RAM is now initialized to something other than 0. Fixes
|
||
|
|
Minna no Taabou no Nakayoshi Dai Sakusen.
|
||
|
|
|
||
|
|
Reassigned "The Money Game" to mapper 155. It doesn't seem to
|
||
|
|
respect the WRAM enable/disable bits. Silly game. And
|
||
|
|
Tatakae!! Rahmen Man.
|
||
|
|
|
||
|
|
Added support for mapper 115(still needs 256KB CHR select), 241, 114,88.
|
||
|
|
|
||
|
|
Attempted to add support for mappers 91, 187.
|
||
|
|
|
||
|
|
Modified frame IRQ to not break so many damn games.
|
||
|
|
|
||
|
|
Fixed sprite hit detection loop.
|
||
|
|
|
||
|
|
Improved support for mappers 80, 90,117,154, 189.

|
|
|

|
|
Reassigned "Devil Man" to mapper 154.
|
||
|
|
|
||
|
|
Removed bogus Trojan header fix in ines.c.

----
|
||
|

Fixed/Worked around(?) compilation problems on gcc 3.2.x.
|
||
|
|
|
||
|
|
.81:
|
||
|
|
----
|
||
|
|
|
||
|
|
More SDL goodies.
|
||
|
|
|
||
|
|
Renamed "Makefile.olinuxsdl" to "Makefile.unixsdl"
|
||
|
|
|
||
|
|
More SDL fixes and cleanups.
|
||
|
|
|
||
|
|
BeOS port is now compiled with the "-no-fpic" flag, which allows
|
||
|
|
me to use my inline assembly. The executable work fine as far as
|
||
|
|
I can tell.
|
||
|
|
|
||
|
|
Added "Makefile.beos". gcc doesn't like my inline assembly
|
||
|
|
used in RefreshLine(),so this port will likely be slightly slower than
|
||
|
|
other x86 ports.
|
||
|
|
|
||
|
|
Added a check to make sure SIGBUS is not equal to SIGSEGV in
|
||
|
|
drivers/cli/main.c. Needed for compiling under BeOS.
|
||
|
|
|
||
|
|
Renamed the "PI" member of the X6502 structure due to conflicts with
|
||
|
|
a defined symbol with some math header files.
|
||
|
|
|
||
|
|
Merged fcelineasm.h into fceline.h
|
||
|
|
|
||
|
|
Fixed(possibly) a possible problem in fcelineasm.h with input register
|
||
|
|
clobbering.
|
||
|
|
|
||
|
|
More SDL changes.
|
||
|
|
|
||
|
|
Added speed throttling code to the CLI code, and added a command
|
||
|
|
line switch "-nothrottle".
|
||
|
|
|
||
|
|
Lots of restructuring/rewriting/merging of the MMC3 code.
|
||
|
|
|
||
|
|
Updated DOS code to use the generic CLI wrapper.
|
||
|
|
|
||
|
|
Reads from $4090 and $4092 now return the current envelope setting
|
||
|
|
in FDS sound emulation. I'm not sure if this is correct... Affects
|
||
|
|
"Ai Senshi Nicole" and "Bio Miracle Bokutte Upa".
|
||
|
|
|
||
|
|
Added native SDL sound support to the SDL code. the "olinuxsdl"
|
||
|
|
now uses this code by default instead of the unixdsp sound code.
|
||
|
|
|
||
|
|
Modified MMC3 IRQ counter emulation. I'll need to watch out to see
|
||
|
|
if it breaks any games. Fixes: MegaMan 3, Gun Nac, Klax(Japanese).
|
||
|
|
|
||
|
|
Changed a few memory reads in x6502.c to use RdRAM instead of RdMem,
|
||
|
|
resulting in a slight speed increase.
|
||
|
|
|
||
|
|
Cleaned up mapper 250 emulation code.
|
||
|
|
|
||
|
|
Added support for iNES mapper 51(thanks to Kevin Horton for the
|
||
|
|
information).
|
||
|
|
|
||
|
|
Merged some iNES mappers corresponding to bootleg multicarts
|
||
|
|
based on MMC3s with mbshare/mmc3.c.
|
||
|
|
|
||
|
|
Added support for iNES mapper 52(thanks to Kevin Horton for the
|
||
|
|
information).
|
||
|
|
|
||
|
|
Made some hacks to the MMC3 emulation code so that I can add support
|
||
|
|
for pirate MMC3 multicarts more easily. I should clean it up later.
|
||
|
|
Moved mapper 44 emulation code to mbshare/mmc3.c.
|
||
|
|
|
||
|
|
Saving screen snapshots will no longer corrupt the frame buffer
|
||
|
|
for one frame(unless memory couldn't be allocated).
|
||
|
|
|
||
|
|
Fixed screen snapshot saving(it was sort of broken due to the
|
||
|
|
changes made to the driver<->emulator interface code; status
|
||
|
|
messages were being saved to the image). FCEUI_SaveSnapshot()
|
||
|
|
no longer returns a value(the request to save a screen snapshot is
|
||
|
|
serviced before status information would be written in the next frame).
|
||
|
|
|
||
|
|
nosprites is now set to 0 before RefreshSprite() returns, to prevent
|
||
|
|
problems if a game turns off the bg and sprites when FetchSpriteData()
|
||
|
|
for the next scanline is called but then turns on sprites when
|
||
|
|
the actual scanline is drawn.
|
||
|
|
|
||
|
|
PPU_hook() is now called more often if PPU_hook is non-null.
|
||
|
|
Made changes to mappers 118, 95, 9, and 10 to compensate.
|
||
|
|
No games seem to be broken, and I added support for mapper 96
|
||
|
|
(though the games aren't very playable because the special controller
|
||
|
|
isn't emulated).
|
||
|
|
|
||
|
|
Romance of the 3 Kingdoms is now recognized to use 16KB ex-WRAM.
|
||
|
|
|
||
|
|
Added support for mapper 185...sort of. I think this is another
|
||
|
|
instance of incompatible hardware being lumped onto one mapper number.
|
||
|
|
Sigh.
|
||
|
|
|
||
|
|
Added support for "Famicom Jump 2" as iNES mapper 153.
|
||
|
|
If a good(as far as I can tell) dump is loaded, FCE Ultra will
|
||
|
|
automatically fix the mapper number.
|
||
|
|
I also made some changes to the mapper 16 IRQ emulation code.
|
||
|
|
|
||
|
|
BRK now sets the I flag.
|
||
|
|
|
||
|
|
Reads from $4015 no longer reset DPCM IRQ.
|
||
|
|
|
||
|
|
Changed emulation of RTI instruction slightly.
|
||
|
|
|
||
|
|
X.IRQlow is now set to 0 in PowerNES().
|
||
|
|
|
||
|
|
The VS Unisystem bit in the iNES header is no longer looked at(
|
||
|
|
I was having too many problems with this bit being set when it
|
||
|
|
shouldn't have been). Now, VS Unisystem emulation is enabled
|
||
|
|
when a known VS Unisystem game is loaded. I also rewrote the VS
|
||
|
|
Unisystem detection function.
|
||
|
|
|
||
|
|
iNES mapper 1 now supports pageable CHR RAM if no CHR ROM is present.
|
||
|
|
Fixes "Family School".
|
||
|
|
|
||
|
|
Mapper 70 no longer has a mirroring control emulated, and I extended
|
||
|
|
the number of 8KB CHR pages supported to 16.
|
||
|
|
|
||
|
|
Cleaned up iNES MMC5 save RAM loading/saving code and added
|
||
|
|
support for MMC1 games with 16KB of RAM(the second 8KB are saved),
|
||
|
|
via CRC32s(currently only Genghis Khan(USA) and Nobunaga's Ambition(
|
||
|
|
USA and Japan) are recognized).
|
||
|
|
|
||
|
|
Added support for the MMC5 Koei game "Ishin no Arashi", in the iNES
|
||
|
|
format(I added an entry with its CRC32 value and the number of 8KB
|
||
|
|
WRAM banks it needs).
|
||
|
|
|
||
|
|
Better iNES mapper 33/48 IRQ counter emulation.
|
||
|
|
|
||
|
|
Added the game "Uchuusen - Cosmo Carrier" to this list. I'm
|
||
|
|
beginning to hate the iNES format more and more...or maybe
|
||
|
|
just Fanwen. :)
|
||
|
|
|
||
|
|
Added the mapper 32 game "Major League" to the list of games
|
||
|
|
that usually need iNES header correction...but in this case, the
|
||
|
|
iNES header cannot specify that this game needs to have one-screen
|
||
|
|
mirroring.
|
||
|
|
|
||
|
|
iNES header information is now printed before any header corrections
|
||
|
|
are made based on a database.
|
||
|
|
|
||
|
|
Fixed a bug in mapper 32 emulation. "Ai Sensei no Oshiete"
|
||
|
|
works now.
|
||
|
|
|
||
|
|
Tried to add support for iNES mappers 245 and 249.
|
||
|
|
|
||
|
|
Fixed the MMC5 read handler to return the data last on the data
|
||
|
|
bus instead of 0xFF when a read was made to an unmapped address.
|
||
|
|
This seems to fix the lockup problems in "Bandit Kings of Ancient
|
||
|
|
China".
|
||
|
|
|
||
|
|
Reversed "Modified the time at which the "y scroll" register is updated
|
||
|
|
during hblank." The changes broke Klax.
|
||
|
|
|
||
|
|
Added an unsigned 64-bit base timestamp variable "timestampbase".
|
||
|
|
Adding this to the 32-bit variable "timestamp" will return
|
||
|
|
the number of cycles executed since emulation started(in the future
|
||
|
|
I'll probably change it to since reset or power toggle).
|
||
|
|
This allowed me to replace "lastn" hack in the MMC1 code with
|
||
|
|
something better.
|
||
|
|
|
||
|
|
Changed my mind and undid the removal of support for old save states.
|
||
|
|
|
||
|
|
Removed support for old save states and in general I won't
|
||
|
|
try to support save states made with previous versions.
|
||
|
|
|
||
|
|
MMC1: Writes to $8000-$FFFF with D7 set will now cause
|
||
|
|
the first MMC1 register to be OR'ed with 0x0C. I'm not sure
|
||
|
|
if this is correct, but it doesn't seem to break anything
|
||
|
|
and it fixes Robocop 3. I'll see if anyone reports games
|
||
|
|
not working in .81 that worked in .80.
|
||
|
|
|
||
|
|
Worked on a generic driver interface wrapper very similar
|
||
|
|
to the driver interface FCE Ultra used to use(I'm getting
|
||
|
|
tired of all of the duplicated driver code). Eventually,
|
||
|
|
the DOS, SVGAlib, and SDL ports will use this wrapper.
|
||
|
|
|
||
|
|
Similar change to the argument parsing code.
|
||
|
|
|
||
|
|
Changed configuration file saving-loading routines and the
|
||
|
|
configuration structure to allow for linking config structures
|
||
|
|
to each other).
|
||
|
|
|
||
|
|
Small fix to the emulation of the MMC5 split screen mode.
|
||
|
|
|
||
|
|
Made Linux SDL code compilable again.
|
||
|
|
|
||
|
|
Changes to MMC5 EXRAM emulation(read/write).
|
||
|
|
|
||
|
|
Fixes to the emulation of the MMC5's split screen mode, based on
|
||
|
|
observations while using CastleVania 3 and a Game Genie(on a real
|
||
|
|
NES).
|
||
|
|
|
||
|
|
Fixed a bug in ines.c that caused any calls to AddExState() from
|
||
|
|
a mapper initialization function to be effectively "erased"(ResetExState()
|
||
|
|
was called after the mapper was initialized). Fixes the VRC7 sound
|
||
|
|
state saving/loading stuff.
|
||
|
|
|
||
|
|
Finished adding support for the MMC5's split screen mode(this does
|
||
|
|
not mean that the support is complete, but at least the intro in
|
||
|
|
"Uchuu Keibitai SDF" works correctly now).
|
||
|
|
|
||
|
|
Worked on adding support for the MMC5's split screen mode. Not
|
||
|
|
completed.
|
||
|
|
|
||
|
|
Reverted to .80's FDS sound code.
|
||
|
|
|
||
|
|
Modified the time at which the "y scroll" register is updated
|
||
|
|
during hblank.
|
||
|
|
|
||
|
|
NSF playing code will now disable FDS sound output on song init
|
||
|
|
(fixes some problems with the Zelda no Densetsu NSF rip).
|
||
|
|
|
||
|
|
Increased the emulated clock speed of the FDS sound emulation code
|
||
|
|
to give better quality output.
|
||
|
|
|
||
|
|
Modified NMI to occur a few cycles later. Fixes BattleToads...but
|
||
|
|
it may have broken other games. Also modified the way NMI's are
|
||
|
|
handled in x6502.c.
|
||
|
|
|
||
|
|
Modified ines.c to memset() GameMemBlock to 0 on virtual power toggle.
|
||
|
|
Also, trainers are now loaded into their own buffer instead of
|
||
|
|
directly into emulated WRAM and copied into emulated WRAM on
|
||
|
|
power toggle; I've been meaning to do this for quite some time.
|
||
|
|
|
||
|
|
Changes to the way the zapper cursor is drawn on the screen.
|
||
|
|
|
||
|
|
FCEUD_WriteSoundData(), FCEUD_BlitScreen(), and FCEUD_UpdateInput()
|
||
|
|
have been combined into one function: FCEUD_Update().
|
||
|
|
|
||
|
|
More fixes to the network play code, and a fix to the Windows network
|
||
|
|
play driver code that fixes(hopefully) a rather evil bug that caused
|
||
|
|
lockups when the remote stopped network play.
|
||
|
|
|
||
|
|
Added code to set the battery-backed bit in RAM if a game needs it,
|
||
|
|
based on CRC32.
|
||
|
|
|
||
|
|
Added more games to the list of games that commonly have bad iNES
|
||
|
|
headers, in ines.c
|
||
|
|
|
||
|
|
Updated docs and usage.h for DOS and Linux regarding the new video
|
||
|
|
mode and the new refresh rates.
|
||
|
|
|
||
|
|
Linux: Fixed a bug with video mode 6(a few upper scanlines were being
|
||
|
|
cut off). Increased the refresh rate of video mode 3 to 120hz.
|
||
|
|
|
||
|
|
Increased the refresh rate of video mode 2 to 65 hz in the Linux port.
|
||
|
|
|
||
|
|
Screen snapshots can now be taken while playing an NSF.
|
||
|
|
|
||
|
|
Added a new sexy tweaked vga mode that I created to the Linux svgalib
|
||
|
|
port. It's 256x224 at a refresh rate of 103hz. Hopefully it won't
|
||
|
|
blow up anyone's monitor. ;)
|
||
|
|
DOS port will follow eventually.
|
||
|
|
|
||
|
|
Modified Makefile.base to produce an executable named "fceu" instead
|
||
|
|
of "fce".
|
||
|
|
|
||
|
|
The plans(cycle-accurate ppu emulation) for .90 were a bit ambitious,
|
||
|
|
and I still need to make other fixes before then.
|
||
|
|
|
||
|
|
Fixed some minor(usually) bugs with setting 256x240 tweaked VGA mode
|
||
|
|
in DOS and Linux ports.
|
||
|
|
|
||
|
|
.80:
|
||
|
|
----
|
||
|
|
|
||
|
|
Cleaned/fixed a few things in the mapper 19 emulation code.
|
||
|
|
Family Circuit '91 still doesn't work quite right... I wonder if
|
||
|
|
it's a bad dump.
|
||
|
|
|
||
|
|
Added input override code to Windows port.
|
||
|
|
|
||
|
|
Added code to fix iNES header information in RAM and suggest
|
||
|
|
changes to the user.
|
||
|
|
|
||
|
|
Added support for iNES mapper 152(to be used with games set to
|
||
|
|
mapper 70, that use one-screen mirroring instead of h/v mirroring).
|
||
|
|
|
||
|
|
Blits using the DirectX blitting function(method?) to the primary
|
||
|
|
surface are now done with the asynchronous flag set(if that
|
||
|
|
fails, a "normal" blit is tried).
|
||
|
|
|
||
|
|
The DirectX blit buffer(secondary surface that FCE Ultra writes to
|
||
|
|
directly and then uses the DirectDraw blit function on to blit
|
||
|
|
to the primary buffer) is now created without specifying it
|
||
|
|
should be in system memory or video memory, except in the case
|
||
|
|
when no hardware blitting is available, and then DDraw is explicitly
|
||
|
|
told to create the surface in system memory.
|
||
|
|
|
||
|
|
Added Family Keyboard support to the DOS port.
|
||
|
|
|
||
|
|
Cleaned up the VRC7 sound emulation code. I need to find a way
|
||
|
|
to save the current sound state in a save state.
|
||
|
|
|
||
|
|
Found out the real name of the "Space Shadow" gun; it's
|
||
|
|
called the "Hyper Shot". I'm still not sure who made it, though.
|
||
|
|
Possibly Bandai did. The interesting thing is that Konami
|
||
|
|
also made a Famicom accessory(dual square boxy things with two buttons
|
||
|
|
on each) with the same name(though there might not be a space in the
|
||
|
|
name).
|
||
|
|
|
||
|
|
Only the upper two bits read from $4016/$4017 are undefined.
|
||
|
|
Bit5 is always 0, though. Fixed the bug in "input.c".
|
||
|
|
Silly kevtris' old documents. New kevtris' brain is always good.
|
||
|
|
|
||
|
|
Family Keyboard support for the Windows port.
|
||
|
|
|
||
|
|
Added support for the Family Basic Keyboard to the Linux port, other
|
||
|
|
ports todo.
|
||
|
|
Might want to add support for the tape recorder at some time.
|
||
|
|
Also mapped the "Scroll Lock" key to disable/enable command keys
|
||
|
|
so that the FBK is more useable. It doesn't disable CTRL C,
|
||
|
|
though...
|
||
|
|
|
||
|
|
Changed a lot of inlined functions in x6502.c to macros so that
|
||
|
|
I could test out some optimization ideas.
|
||
|
|
|
||
|
|
DOS code updates for game input override support.
|
||
|
|
|
||
|
|
Small optimzation to opcode $4c, and relative jumps.
|
||
|
|
|
||
|
|
Added some code to ines.c to set controller information in
|
||
|
|
FCEUGameInfo(returned by FCEUI_LoadGame()) based on crc32 values.
|
||
|
|
|
||
|
|
Updated user documentation and usage.h for DOS and SVGAlib input
|
||
|
|
command-line changes.
|
||
|
|
|
||
|
|
Added an option to disable the four-score(to Windows and Linux ports
|
||
|
|
so far).
|
||
|
|
|
||
|
|
Updated Windows interface to support the new Famicom expansion
|
||
|
|
devices.
|
||
|
|
|
||
|
|
(Re)Added support for the Famicom 4-player device.
|
||
|
|
|
||
|
|
Improved Zapper emulation...sort of. It still needs a lot of work. :/
|
||
|
|
|
||
|
|
Added *partial* support for the "Space Shadow" gun.
|
||
|
|
|
||
|
|
Added support for the Arkanoid controller(both NES and Famicom style).
|
||
|
|
|
||
|
|
Added code to support the extension Famicom input devices.
|
||
|
|
|
||
|
|
Added PAL scanline start/end drawing settings to Windows port.
|
||
|
|
|
||
|
|
Added pause emulation key(F2) to Windows port.
|
||
|
|
|
||
|
|
In the process of rewriting/fixing up input code stuff.
|
||
|
|
|
||
|
|
Minor bug fix to Power Pad emulation code.
|
||
|
|
|
||
|
|
VS Hogan's Alley and VS Duck Hunt automatically select the zapper
|
||
|
|
now(though it only works on the SVGAlib port).
|
||
|
|
|
||
|
|
Undid some FDS sound code changes introduced in 0.76 that totally
|
||
|
|
screwed up sound. Oops.
|
||
|
|
|
||
|
|
Added code to allow different settings for first/last scanline
|
||
|
|
drawn while in PAL emulation mode, to the Linux and DOS ports.
|
||
|
|
|
||
|
|
Added convenience(it's not necessary, but it reduces redundant and
|
||
|
|
confusing code in the driver code) function
|
||
|
|
FCEUI_GetCurrentVidSystem(int *slstart, int *slend).
|
||
|
|
|
||
|
|
Updated file "TODO".
|
||
|
|
|
||
|
|
Changed #include <unzip.h> to #include "zlib/unzip.h"
|
||
|
|
in file.c.
|
||
|
|
|
||
|
|
NSF 6502 player now initialized the stack pointer on reset.
|
||
|
|
|
||
|
|
Worked on de-emphasis emulation code quite a bit.
|
||
|
|
The deemphasized palette calculated at the end of the frame is now
|
||
|
|
based on what deemphasis bits were set for the longest during
|
||
|
|
the screen(sampling interval is a scanline) update loop.
|
||
|
|
Added a "static" deemphasized palette at $40-$7F in the palette table.
|
||
|
|
This corresponds to the colors when all of the deemphasis bits are set.
|
||
|
|
I did this to fix the PAL game "Noah's Ark", without breaking
|
||
|
|
anything else. The only downside is a slight speed loss(~2% on
|
||
|
|
my system when sound is disabled), but this is acceptable to me,
|
||
|
|
at least.
|
||
|
|
Maybe it's time to write hi/true-color ppu drawing code...
|
||
|
|
|
||
|
|
|
||
|
|
Fixed an out of bounds array access in svga.c in SetNESDeemph().
|
||
|
|
The variable "lastd" in svga.c was being initialized to the wrong value.
|
||
|
|
Thanks to "Jarod CANAL" for pointing this out.
|
||
|
|
|
||
|
|
Removed FCEUI_SetFirstRenderedLine or whatever it was called and
|
||
|
|
the function to set the last line. Replaced with:
|
||
|
|
void FCEUI_SetRenderedLines(int ntscf, int ntscl, int palf, int pall);
|
||
|
|
|
||
|
|
Changed SetVidSys(int w) to ResetVidSys() in fce.c. Reenabled
|
||
|
|
PAL/NTSC emulation overrides based on game loaded(really only useful
|
||
|
|
for NSFs and UNIFs now).
|
||
|
|
|
||
|
|
UNIF loading code now recognizes the chunk "CTRL" and tries
|
||
|
|
to use it. Only the svgalib code supports overriding of input
|
||
|
|
settings based on game loaded, now, though...
|
||
|
|
The user is still going to have to configure powerpad settings
|
||
|
|
on his/her own.
|
||
|
|
|
||
|
|
Fixed return values of FCEU_fseek() and fixed a problem in unif.c
|
||
|
|
related to it.
|
||
|
|
|
||
|
|
Changed mechanism for how FCE Ultra tells the driver
|
||
|
|
code what type of system is being emulated. A structure of
|
||
|
|
type "FCEUGI" is returned from FCEUI_LoadGame().
|
||
|
|
|
||
|
|
Fixed a major mapper 64 emulation bug introduced in 0.76.
|
||
|
|
|
||
|
|
Modified BlitVidHi() in drivers/win/video.c to speed it up.
|
||
|
|
|
||
|
|
Added support for loading the iNES-format Game Genie ROM image.
|
||
|
|
|
||
|
|
Removed ggrom.h and added code to load the Game Genie ROM
|
||
|
|
image from a file.
|
||
|
|
|
||
|
|
Added Windows netplay.c. (new: the user exiting the emulator
|
||
|
|
while stuck in a blocking recv() or send() loop now works.)
|
||
|
|
|
||
|
|
Fixed a vram address register bug in fce.c that I created when I got
|
||
|
|
rid of the pair/dpair data types.
|
||
|
|
|
||
|
|
Added new mappers/92.c
|
||
|
|
|
||
|
|
Removed mappers/92.c until I can contact LULU or rewrite it.
|
||
|
|
|
||
|
|
drivers/win changes. Removed netplay.c until I can rewrite it.
|
||
|
|
|
||
|
|
Got rid of pair/dpair data types.
|
||
|
|
|
||
|
|
Got rid of silly "TempArray" thing.
|
||
|
|
|
||
|
|
Began adding GPL headers to files. FCE Ultra is going to be in
|
||
|
|
a state of legal limbo for the next few days...
|
||
|
|
|
||
|
|
Replaced crc32.c and crc32.h, and added some #ifdef's and #defines
|
||
|
|
to use the crc32 code in zlib instead if zlib is linked with
|
||
|
|
FCE Ultra.
|
||
|
|
|
||
|
|
More fixes to sb.c.
|
||
|
|
|
||
|
|
Cleaned up drawing.h and ggrom.h(even though ggrom.h will *probably*
|
||
|
|
be removed before the next release).
|
||
|
|
|
||
|
|
Redid frameskip code.
|
||
|
|
|
||
|
|
Rewrote necessary pieces of sb.c and sb.h and fixed quite a few
|
||
|
|
bugs. I still need to test it on various other sound cards, though.
|
||
|
|
|
||
|
|
Rewrote(more like "recreated in my own image") DOS keyboard driver.
|
||
|
|
Removed unused "keyscan.h" from drivers/svgalib
|
||
|
|
|
||
|
|
Rewrote part of(the parts that Marat wrote - the connection and
|
||
|
|
closing parts) the Linux TCP/IP network play code. I guess it works,
|
||
|
|
but I haven't tested it very much. In any case, it's still dangerous
|
||
|
|
to use network play in FCE Ultra with SVGAlib, since recv() or send()
|
||
|
|
might block and since the keyboard is in raw mode, you have a problem.
|
||
|
|
Maybe a future SVGAlib will fix the general problem of lockups if
|
||
|
|
keyboard_update() isn't called, though it is only partly SVGAlib's
|
||
|
|
problem...
|
||
|
|
|
||
|
|
Fixed FCEU_fseek() when used with a compressed file in the PKZIP
|
||
|
|
format that has been loaded. Fixes a UNIF loading problem.
|
||
|
|
Also added a check to the return value of FCEU_fseek() in unif.c.
|
||
|
|
|
||
|
|
Replaced Marat's 6502 emulation core with my own.
|
||
|
|
It should be fully functional, but as always, I don't know if
|
||
|
|
I implemented the undocumented instructions correctly.
|
||
|
|
Several things are correct in this new core that were not in
|
||
|
|
Marat's(D flag is no longer cleared by interrupts, for example).
|
||
|
|
|
||
|
|
Altered mapper 16 irq counter emulation slightly.
|
||
|
|
|
||
|
|
Fixed the behavior of the SXA, SYA, and XAS opcodes based on the
|
||
|
|
documentation I have. I'm not sure what happens when page crossing
|
||
|
|
occurs with those instructions on a real NES, though.
|
||
|
|
Also CHANGED(not fixed) emulation of opcode $8B("XAA").
|
||
|
|
|
||
|
|
Changed some of the M* functions(absolute indexed and maybe some others)
|
||
|
|
to perform dummy reads.
|
||
|
|
|
||
|
|
Changed some of the macros in m6502.c to inlined functions so
|
||
|
|
that I can modify and examine them more easily.
|
||
|
|
|
||
|

.77:
|
||
|
|
----
|
||
|
|
|
||
|
|
Fixed a silly network play bug(in the global network play code)
|
||
|
|
that caused excessive lag.
|
||
|
|
|
||
|
|
Added a "niceness" setting to the sound configuration dialog.
|
||
|
|
Removed obsolete information from the dialog.
|
||
|
|
|
||
|
|
Fixed speed throttling code in Windows port when PAL emulation is
|
||
|
|
disabled/enabled and a new game hasn't been loaded yet.
|
||
|
|
|
||
|
|
Commented out a printf() to debug stuff in fds.c(oops).
|
||
|
|
|
||
|
|
Applied PK's joystick patch to the osdl code. It allows the user
|
||
|
|
to map axes and it fixes a joystick button mapping configuration saving
|
||
|
|
bug.
|
||
|
|
|
||
|
|
Added two command line options new to Linux port to DOS port.
|
||
|
|
Just need to test them...
|
||
|
|
|
||
|
|
Added some stuff to unif.c to allow for boards that can support
|
||
|
|
CHR RAM instead of CHR ROM(darn Sachen boards...). Fixes UNIF
|
||
|
|
version of "Q-Boy".
|
||
|
|
|
||
|
|
Added command line option "-snapname" to Linux port. I'll add it
|
||
|
|
to the Windows port as well, but probably not to the DOS port.
|
||
|
|
|
||
|
|
Added clip option to Linux port.
|
||
|
|
|
||
|
|
Fixed sound logging(in Windows port) so that multiple recording
|
||
|
|
sessions now work.
|
||
|
|
|
||
|
|
Added an option to clip the leftmost and rightmost 8 columns
|
||
|
|
of graphics in the Windows port.
|
||
|
|
|
||
|
|
Added a submenu that lists recently opened files, in the Windows
|
||
|
|
port.
|
||
|
|
|
||
|
|
.76:
|
||
|
|
----
|
||
|
|
|
||
|
|
Updated porting.txt.
|
||
|
|
|
||
|
|
Added speed throttling code to Windows port that's used when sound is
|
||
|
|
disabled(and an option in the "Miscellaneous"
|
||
|
|
configuration window to disable it).
|
||
|
|
|
||
|
|
Added cheat interface to DOS build.
|
||
|
|
|
||
|
|
A few tweaks to the text cheat interface code in the cheat listing code.
|
||
|
|
Added a command to quickly toggle the status of the cheat(though a
|
||
|
|
cheat can still be disabled/enabled by (M)odifying the cheat).
|
||
|
|
|
||
|
|
Support for UNIF UNL-TC-U01-1.5M board added. Same credits as below.
|
||
|
|
|
||
|
|
Rewrote mapper 228 code just for the heck of it(actually, I couldn't
|
||
|
|
figure out why some(about two) of the games in the Action 52 cart
|
||
|
|
weren't working in .75(and .76). I traced it back to .71, where an apparent bug in
|
||
|
|
the undocumented 6502 opcode emulation allowed it to work, which
|
||
|
|
was later fixed for the .72 release(opcode 0x7C)). I'm thinking
|
||
|
|
that the dump is bad...
|
||
|
|
|
||
|
|
Added a few crc32 checks to ines.c to check for and report when
|
||
|
|
a known(by me) bad(hacked or bad dump) game is loaded.
|
||
|
|
|
||
|
|
Added support for the following UNIF boards. Thanks to Quietust
|
||
|
|
and Kevin Horton for the information. Some problems still exist
|
||
|
|
with a few games that use these boards, though...
|

|

|
|
Fixes to some stuff in cart.c(for example, calling setprg32() when
|
||
|
|
only 16kb of prg data is present now works).
|
||
|
|
|
||
|
|
Added support for iNES mapper 189.
|
||
|
|
|
||
|
|
Tried to add support for the UNIF board "UNL-H2288". Failed.
|
||
|
|
|
||
|
|
Updated "cheat.txt" to fix a few typos and added an example of finding
|
||
|
|
and adding a cheat using the Linux port's text interface. The actual
|
||
|
|
section on the Linux cheat interface still needs to be written, however.
|
||
|
|
|
||
|
|
Changed network play code in the Windows port and fixed a bug.
|
||
|
|
Fixed a similar bug in the Linux netplay code....sort of.
|
||
|
|
|
||
|
|
A few cosmetic changes to the dialogs in the Windows port.
|
||
|
|
|
||
|
|
Fixed sound initialization on the Windows port(it was being initialized
|
||
|
|
when FCE Ultra started even if it was disabled by the user. Oops.).
|
||
|
|
|
||
|
|
Joystick button configuration code in Windows port changed slightly
|
||
|
|
to be more useable.
|
||
|
|
|
||
|
|
Changed reference to video mode 5 in the linux port to "1 per 4".
|
||
|
|
It may not be very meaningful, but it is certainly better
|
||
|
|
than "TV Emulation". I'll change the Windows port reference later.
|
||
|
|
|
||
|
|
Documented video mode 7(320x240) for the Linux port. Also added
|
||
|
|
a check for the FBDev driver in order to use this mode instead
|
||
|
|
of a tweaked vga mode if that driver is being used.
|
||
|
|
|
||
|
|
Added/Fixed cheat interface for Linux port. It's still not perfect,
|
||
|
|
though. The code is ugly...
|
||
|
|
|
||
|
|
Callback function for FCEUI_ListCheats() now receives
|
||
|
|
status information(enabled/disabled).
|
||
|
|
|
||
|
|
Callback functions for cheat functions now must return 0 to
|
||
|
|
stop listing cheats or 1 to continue.
|
||
|
|
|
||
|
|
Fixed a problem(the cheat code was reading in cheats
|
||
|
|
for address $0000 from cheat files if any blank lines were present).
|
||
|
|
|
||
|
|
SDL port zlib changes(linked dynamically to zlib now).
|
||
|
|
|
||
|
|
More changes to envelope decay + looping on code. No longer
|
||
|
|
depends on value @ $4017. It now sounds correct based on some
|
||
|
|
tests I did with SMB3 and a GG, but Goonies 2 doesn't sound right(
|
||
|
|
based on a sound file sent to me by another person).
|
||
|
|
|
||
|
|
Added support for iNES mapper 140. Thanks to Quietust for the
|
||
|
|
information.
|
||
|
|
|
||
|
|
I need to figure out how to deal with the problem of so many
|
||
|
|
bad NSFs that most people consider good...
|
||
|
|
|
||
|
|
Changed envelope decays a bit. Their behavior now depends on bit
|
||
|
|
7 of $4017. I don't know if this is right...
|
||
|
|
|
||
|
|
Addition of debug.c for some debugging stuff.
|
||
|
|
|
||
|
|
Updated zlib to 1.1.4.
|
||
|
|
|
||
|
|
Modified code in various files to allow UNIF games to override
|
||
|
|
current selected video system emulation(NTSC or PAL). Need to
|
||
|
|
make sure this really works.
|
||
|
|
|
||
|
|
Changed sound.c to prevent desynchronization during network play.
|
||
|
|
This might slow down sound emulation slightly, especially when
|
||
|
|
sound emulation is disabled. I really don't care...
|
||
|
|
|
||
|
|
Updating network play code. More info later...
|
||
|
|
|
||
|
|
Moved the sound/video/etc output code in EmLoop() to the top of the
|
||
|
|
for(;;) loop so that initialization prior to calling EmLoop() will
|
||
|
|
be the same as initialization done during a call to a FCEUD_* function.
|
||
|
|
|
||
|
|
A few very small changes to sound emulation in fds.c.
|
||
|
|
|
||
|
|
Changed unlink() to remove() in cheat.c and removed the including
|
||
|
|
of the header file unistd.h.
|
||
|
|
|
||
|
|
Split up the cc=... statement in RefreshLine() to make it easier
|
||
|
|
to read and not ambiguous(to Borland's C compiler).
|
||
|
|
|
||
|
|
Changed a lot of the function declarations in cheat.c. I'll need
|
||
|
|
to verify that cheat searching still works ok and that cheats still work
|
||
|
|
ok. I'll also need to update the Windows(and Linux console) cheat code
|
||
|
|
to prevent compiler warnings.
|
||
|
|
|
||
|
|
Fixed various minor code problems(not minor if you want to use a
|
||
|
|
compiler besides gcc). This is an ongoing process...
|
||
|
|
|
||
|
|
Removed bit fields after reading about and thinking about possible
|
||
|
|
portability problems, though I kept some optimizations in fceline.h
|
||
|
|
|
||
|
|
Minor code simplification in drivers/win/joystick.c(replaced
|
||
|
|
"case 200 ... 207" and "case 208 ... 215".
|
||
|
|
|
||
|
|
Modified some code to use bit-fields in the graphics rendering code
|
||
|
|
in fce.c and fceline.h. gcc seems to be able to optimize the new
|
||
|
|
code to run faster.
|
||
|
|
|
||
|
|
Fixed m6502.c and fce.c to initialize variables on virtual power
|
||
|
|
toggle. This should fix network play on the Windows port.
|
||
|
|
I'm also in the process of cleaning up fce.c.
|
||
|
|
|
||
|
|
.75:
|
||
|
|
----
|
||
|
|
Fixed directories configuration stuff in Windows port(corresponds
|
||
|
|
to .75r2).
|
||
|
|
|
||
|
|
More changes to square wave channel envelope/volume emulation...
|
||
|
|
Changes described in the large paragraph some lines down have been
|
||
|
|
abandoned.
|
||
|
|
|
||
|
|
Added a command line switch to set the volume in the dos port.
|
||
|
|
|
||
|
|
Changed Windows sound configuration dialog. Now buffer length is
|
||
|
|
specified in time, not samples. I also added a volume control.
|
||
|
|
|
||
|
|
Reduced the volume on 8-bit sound output on all ports by 1/2.
|
||
|
|
|
||
|
|
Added a function FCEUI_SetSoundVolume(). Added support for setting
|
||
|
|
the volume via the command line in the Linux port, other ports coming
|
||
|
|
soon.
|
||
|
|
|
||
|
|
Changed FCEUD_WriteSoundData() again. No longer has a "Check"
|
||
|
|
argument. All clipping(ugh) is done internally now.
|
||
|
|
|
||
|
|
Added a directories configuration dialog to the Windows port. I worked
|
||
|
|
on it too long and I became a zombie, so it might have a few bugs.
|
||
|
|
That's what guine...err...users are for. ;) Don't expect me to do
|
||
|
|
anything like this for any other port, though. I don't feel like
|
||
|
|
doing it on the DOS port, and the Linux and other UNIXy ports shouldn't
|
||
|
|
really need it.
|
||
|
|
|
||
|
|
Made some changes to the rectangle/square wave channel emulation to
|
||
|
|
fix the pops in SMB. I have no idea if what I did is correct. To
|
||
|
|
be honest, I'm not sure I know EXACTLY what I did, but it's something
|
||
|
|
like this: Writes to $4003/$4007 now reset the duty cycle count
|
||
|
|
and reload the cycle counter with the current wavelength. Writes to
|
||
|
|
$4003/$4007 now do not update the amplitude output of the channels; they
|
||
|
|
will be updated after the cycle counter hits 0(or below).
|
||
|
|
|
||
|
|
More information in iNES informational output.
|
||
|
|
|
||
|
|
Minor changes to mappers/16.c.
|
||
|
|
|
||
|
|
Increased the volume of the VRC6's sawtooth wave channel.
|
||
|
|
|
||
|
|
Added more information to the RAM cheat guide.
|
||
|
|
|
||
|
|
Changed the triangle wave generation code slightly. I decided
|
||
|
|
to remove support for the higher-frequency triangle waves, as they
|
||
|
|
are too cpu-costly to create and are probably not very audible on a
|
||
|
|
real NES anyway.
|
||
|
|
|
||
|
|
Major changes to how sound is mixed. This necessitated a high pass
|
||
|
|
DC-offset removing filter, and a low-pass filter just to make things
|
||
|
|
sound better. ^_^
|
||
|
|
Note: FCEUD_WriteSoundData() no longer needs to clear the waveform
|

|
|
|

|
Fixed JMP ($xxxx) - now handles wrapping like it occurs on a real 6502
|
||
|
|
(hopefully; I'm assuming that the same holds true for the NES' cpu).
|
||
|
|
|
||
|
|
Added the ability to load a custom global palette in the DOS port.
|
||
|
|
|
||
|
|
Fixed bug in drivers/common/unixdsp.c(wrong return value if sample
|
||
|
|
rate was out of range).
|
||
|
|
|
||
|
|
Many sound fixes... - Frequency sweeps, length counter stuff,...
|
||
|
|
|
||
|
|
Changed Windows port to use IDirectInput7 and IDirectInputDevice7
|
||
|
|
interfaces.
|
||
|
|
|
||
|
|
Fixed a Game Genie bug in the core emulation code. It only appeared
|
||
|
|
in the Windows port, though. (Enabling gg emulation, loading a game,
|
||
|
|
and then disabling gg emulation and loading a new game while in the
|
||
|
|
gg code entry screen would cause the new loaded game to not work
|
||
|
|
correctly).
|
||
|
|
|
||
|
|
Modified windows port to use the config saving/loading stuff in
|
||
|
|
drivers/common/config.c
|

|
||
|
|
Mapper 45 cleanups/fixes.

Yay.
|
||
|
|
|
||
|
|
Fixed a large number of overcomplicated code and silly bugs in
|
||
|
|
drivers/common/config.c. This changes the format of the configuration
|
||
|
|
structure, too. Also added support for saving/loading strings with
|
||
|
|
automatic memory allocation when strings are loaded.
|
||
|
|
|
||
|
|
Minor change in InitNetplay().
|
||
|
|
|
||
|
|
Fixed bad type conversions for pointers to functions and fixed
|
||
|
|
some bad declarations of functions.
|
||
|
|
|
||
|
|
Reenabled zlib support for the sdl build. I need to pay attention
|
||
|
|
to patches that modify lines than don't fit on my screen.
|
||
|
|
|
||
|

|
||
|
|
in the non-client area of the window.
|
||
|
|
|

Rewrote the function "FCEU_MakeFName()".
|
||
|
|
|
||
|
|
Removed crc32.h from mappers directory.
|
||
|
|
|
||
|
|
Modified some of the window resizing code in the Windows port.
|
||
|
|
|
||
|
|
Added support for waiting for vblank/double buffering to the Windows
|
||
|
|
port.
|
||
|
|
|
||
|

After an NSF file is loaded, information about its header is now
|
||
|
|
displayed.
|
||
|
|
|
||
|
|
Fixed a typo in the Namco 106 extra ram handling code.
|
||
|
|
|
||
|
|
Improved the quality of the Namco 106's extra sound channels.
|
||
|
|
- Thank Mamiya and Applepie(real name?) for info.
|
||
|
|
|
||
|
|
When an NSF file is being played, FCE Ultra will no longer go through
|
||
|
|
its scanline rendering loop. This speeds up NSF playback considerably.
|
||
|
|
|
||
|
|
Updated "porting.txt".

|
|
|
||
|
|
Moved some stuff from DriverInterface() to their own functions.
|
||
|
|
|
||
|
|
Fixed some iNES mapper 18 IRQ counter emulation bugs. "Ninja Jajamaru -
|
||
|
|
Ginga Dai Sakusen" now works.
|
||
|
|
|
||
|
|
Rewrote large pieces of the mapper 64 code. "Skull and Crossbones"
|
||
|
|
still doesn't work, though.
|
||
|
|
|
||
|
|
Changed format of iNES header information output, added "ROM CRC32" info.
|
||
|
|
|
||
|
|
Modified the way cycle timing is done slightly. No change
|
||
|
|
for NTSC emulation, but PAL emulation is a little more accurate.
|
||
|
|
|
||
|
|
Changed the behavior of indirect indexed(I hope I got that right ;))
|
||
|
|
instructions to behave more like a real 6502(junk reads are now
|
||
|
|
performed).
|
||
|
|
|

|
|
A few optimizations/cleanups in m6502.c.

|
|
as "Trojan" and "VS Duck Hunt") that were broken in .71 and .72 now
|
||
|
|
work ok.
|
||
|
|
* Added support for iNES mapper 82. Thanks to those who work on
|
||
|
|
"unofficial nester".
|
||
|
|
* Added support for iNES mapper 250(used by "Time Diver Avenger").
|
||
|
|
* Fixed the documentation to show that iNES mappers 48, 83, and 232
|
||
|
|
are supported.
|
||
|
|
* Removed various pieces of stale code and fixed a few minor bugs.
|
||
|
|
* Fixed a triangle wave channel bug(the channel was sometimes enabled
|
||
|
|
when it shouldn't have been).
|
||
|
|
* Writing to $4010 with the upper bit clear now acknowledges the DPCM
|
||
|
|
IRQ. This appears to fix "Stunt Buggies".
|
||
|
|
* Rewrote pieces of the Zapper emulation code to be cleaner and more
|
||
|
|
accurate.
|
||
|
|
* Rewrote the VS Unisystem dip switch drawing code.
|
||
|
|
* Simplified the setting of VS Unisystem dip switches. The "V" key
|
||
|
|
now toggles viewing AND editing of dip switches.

|
|
* Removed some (apparently) unused MMC5 sound emulation code.
|
||
|
|
* Changed the behavior of $2003 and $4014 to better simulate what occurs
|
||
|
|
in a real NES.
|
||
|
|
* Fixed a few bugs in the undocumented 6502 opcode emulation code.
|
||
|
|
The Game Genie code "NUTANT" for SMB 3 works correctly now, at
|
||
|
|
least(previously it caused the game to lock up at the end of levels).
|
||
|
|
* Rewrote large pieces of the 6502 memory fetching code, resulting
|
||
|
|
in a slight slowdown in the speed of emulation. Benefits include:
|
||
|
|
Game Genie emulation now works(again) and 6502 emulation is more
|
||
|
|
accurate.
|
||
|
|
* Added support for iNES mapper 72. Thanks to rinao for the information.
|
||
|
|
* Fixed support for iNES mapper 77(used by Napoleon Senki).
|
||
|
|
* Fixed/Added support for iNES mapper 226. Apparently I made a mistake
|
||
|
|
in the documentation. Thanks to Mark K. for the information.
|
||
|
|
* Added support for iNES mapper 227. Thanks to Mark K. for the
|
||
|
|
information.
|
||
|
|
* Added support for iNES mapper 234(used by the Maxi-15). Thanks
|
||
|
|
to Mark K. for the information. Note that many of the Maxi-15
|
||
|
|
ROM images on the Internet have corrupt CHR data(graphics), or the
|
||
|
|
mapper number is set incorrectly(usually to 11). Use a utility to
|
||
|
|
fix the mapper number.
|
||
|
|
* Added support for the following UNIF boards(prefixes omitted):
|
||
|
|
- EKROM (and fixed the reference to "Gemfire" in the documentation).
|
||
|
|
- HKROM
|
||
|
|
* Added the ability to enable and disable individual RAM cheats.
|
||
|
|
* Fixed some problems with the cheat search code(the NES' internal
|
||
|
|
RAM was being searched differently than any external RAM, which
|
||
|
|
was being search incorrectly).

|
|
* Fixed a problem/misunderstanding regarding the upper scanline.
|
||
|
|
It can now be displayed again.
|
||
|
|
* More accurate sprite hit emulation(fixes the title screen of
|
||
|
|
"Ultimate Stuntman").
|
||
|
|
* VRAM bank switching for iNES mapper 4 is now possible(and enabled
|
||
|
|
for all mapper 4 games without CHR ROM). Fixes "Tenchi o Kurau 2".
|
||
|
|
* Added support for the Famicom's four-player adapter and the ability
|
||
|
|
to enable it(it is disabled by default to prevent compatibility
|
||
|
|
problems).
|
||
|
|
* Added an option(under miscellaneous configuration) to automatically
|
||
|
|
open the "File Open" dialog box when FCE Ultra is started.
|
||
|
|
* Sound sampling rate is now configurable.
|
||
|
|
* Fixed some bugs in the DirectSound code.
|
||
|
|
* Joystick button configuration is a little more user friendly(and

* Added support for the Famicom Disk System's extra sound channel.
|
||
|
|
* Updated the version of Tatsuyuki Satoh's OPL2 emulator used in
|
||
|
|
FCE Ultra from .36f to .37a. The sound quality in "Lagrange Point"
|
||
|
|
seems to have improved.
|
||
|
|
* Added support for iNES mapper 242(used by "Wai Xing Zhan Shi").
|
||
|
|
* Fixed a network play bug that could cause desynchronizations
|
||
|
|
if more than one network play session occured since FCE Ultra
|
||
|
|
was started. This bug only showed up on the Windows port, though.
|
||
|
|
* Increased the volume of the noise and triangle sound channels.
|
||
|
|
* Fixed a save state loading bug.
|
||
|
|
* Fixed a small memory leak that was being caused by the VRC7
|

|
|
* Rewrote command line option parsing code.
|

|
|
* Fixed a problem(if FCE Ultra was configured to connect to a remote
|

|
|
host and the remote host was given as an IP address, and the IP
|
||
|
|
address couldn't be reverse resolved, which is commonly the case

* Fixed an overflow bug that occured when $4014 was written to
|
||
|
|
during certain(rare) conditions.
|
||
|
|
* Fixed a few save state bugs.
|

|
||
|
|
* Fixed a sound frame IRQ emulation bug. "Qix" works now.
|
||
|
|
* Added UNIF support. Some of the board emulation is still a bit
|
||
|
|
buggy, though. Look at the documentation for a list of supported
|

|
|
fixed a few other problems with the documentation.
|
||
|
|
* Added support for loading files in the PKZIP and gzip
|
||
|
|
compressed file formats via zlib.
|
||
|
|
* Added the ability to configure the first scanline and the last
|
||
|
|
scanline to draw to the screen. Enabling PAL emulation no longer
|
||
|
|
will cause all 239 scanlines to be displayed, though an option
|
||
|
|
to override these settings for when PAL emulation is enabled may
|
||
|
|
be in the next version.
|
||
|
|
* Fixed a bug that would cause the emulated D-pad of virtual gamepads
|
||
|
|
emulated through the keyboard to be duplicated through "higher"
|
||
|
|
virtual gamepads(gamepad 1 would affect 2,3,4; gamepad 2 would

|
|
to a multiple of the NES' screen dimensions nearest to the user
|
||
|
|
selected dimensions. (Windows)
|
||
|
|
* Added an option to use buttons instead of axes on physical joysticks
|
||
|
|
for the emulated D-Pad. This is useful for some digital joysticks. (Windows)
|
||
|
|
* Fixed a bug that would cause FCE Ultra to crash if sound were
|
||
|
|
disabled during emulation. (Windows)
|
||
|
|
* Added the ability to "fast forward" emulation.
|
||
|
|
* Added an option to allow more than 8 sprites per scanline to be
|
||
|
|
displayed.
|
||
|
|
* Added an option to save all extra non-volatile game data
|
||
|
|
(such as battery-backed RAM) in a directory under FCE Ultra's
|
||
|
|
base directory(as opposed to the directory the game is located in).
|
||
|
|
* Added an option to allow the emulator to change to a full screen
|
||
|
|
video mode once a new game is loaded. (Windows)
|
||
|
|
* Rewrote pieces of DirectInput joystick handling code. Hopefully
|
||
|
|
it should increase compatibility. (Windows)
|
||
|
|
* Added the ability to automatically obtain button numbers when
|
||
|
|
configuring joysticks, by pressing buttons on the joystick.
|
||
|
|
* Added the ability to close the current game(decreases CPU usage). (windows)
|
||
|
|
* Increased the speed of various function calls by passing
|
||
|
|
arguments to functions through registers instead of through the
|
||
|
|
stack.
|
||
|
|
* Added emulation of the MMC5's raw PCM register.
|
||
|
|
* Added the ability to save/load save states while network play
|
||
|
|
is occuring.
|
||
|
|
* Having PAL emulation enabled will no longer override the
|
||
|
|
NTSC/PAL settings in NSF headers.
|
||
|
|
* Fixed a bug that got into the .54 release. Extraneous data was
|
||
|
|
being returned on reads from $2002, which caused problems
|

|
|
any directory component(such as "fceu SuperBlah.nes").
|

|
* Fixed an iNES mapper 118 emulation bug that got into the code
|
||
|
|
in a recent code cleanup. "Armadillo" is playable again.
|
||
|
|
* Fixed a typo(and bug) in the MMC5 emulation code.
|
||
|
|
* Data returned from emulated reads to "unmapped" areas or
|
||
|
|
memory locations where bits are undefined should now be correct.
|
||
|
|
* Fixed emulation of the sprite memory transfer register $4014.
|
||
|
|
It now takes into account the last value written to $2003 and
|
||
|
|
starts the transfer to that location in sprite memory(like on
|
||
|
|
a real NES).
|
||
|
|
* Added a video configuration dialog box. (Windows)

|
|
floating-point math.
|

----
|
||
|
|
|
||
|
|
* Many bug fixes.
|
||
|
|
* Sound code partially rewritten to improve quality(near-perfect
|
||
|
|
raw PCM now) and eliminate the need for a separate thread.
|
||
|
|
This created a small problem with network play, though, so read
|
||
|
|
the network play notes section. Also, synchronizing to
|
||
|
|
vertical blank has been removed.
|
||
|
|
* Rewrote other pieces of sound code. No more "buzzing" in MegaMan 2,
|
||
|
|
Codemasters games' intros, etc.
|
||
|
|
* Added support for the NES Zapper and the VS Unisystem's light
|
||
|
|
gun. Be sure to read "Light Gun Notes".
|
||
|
|
* Changed save state format. Save states should now be much
|
||
|
|
smaller for most games. Most(not all) save states created with
|
||
|
|
an older version should work.
|
||
|
|
* Added support for VS Duck Hunt and VS Hogan's Alley.
