About libretro port

BIOS files location

• bios.rom
  
• font.rom or font.bmp
  
• itf.rom
  
• sound.rom
  
• (bios9821.rom or d8000.rom
  But I never see good dump file.)
  
• 2608_bd.wav
  
• 2608_sd.wav
  
• 2608_top.wav
  
• 2608_hh.wav
  
• 2608_tom.wav
  
• 2608_rim.wav
  

BIOS files locate in 'np2kai' directory at BIOS directory (configured by RetroArch).
Configure file (np2kai.cfg) is made in 'np2kai' BIOS directory.

To get BIOS files, you need actual PC-98 machine.
Start MS-DOS on the actual PC-98 and execute the GETBIOS command
(included in the np2tool/np2tool.zip floppy image)
to create BIOS files.

Rhythm sound files are dumped from PC-98 machine with FM sound gen.
You can get sound files from here.

Fonts

NP2kai recommend font is using font.rom.

Windows

You can use 'MS Gothic'. To install add your windows,
'install files Easten Asian languages' at 'language' option.

After installation, 'msgothic.ttc' file's shortcut named 'default.ttf' put in BIOS directory.
(Already exist 'font.tmp', delete this.)
And start NP2kai.

Linux

I recommend use 'Takao Gothic'.
Install with follow command. After installation, 'TakaoGothic.ttf' file's shortcut put in BIOS directory.

sudo apt install 'fonts-takao-*'

and

ls -n /usr/share/fonts/truetype/takao-gothic/TakaoGothic.ttf BIOSdirectory/default.ttf'

Already exist 'font.tmp', delete this.
And start NP2kai.

You can use 'Noto sans mono CJK', 'MS Gothic'(Japanese) also.

NP2 menu (different libretro menu)

NP2 menu is shown F12 or mouse middle button or L2.
NP2 menu can swap FDD/HDD diskimages.(Swapping HDD need reset.)

Mounting/Swaping Disk and HDD/CD mounting at start

Using libretro contents .m3u file listed floppy disk images,
You can use libretro swap interface.
(This file must be wiritten in UTF-8.)

1st.d88
2nd.d88
3rd.d88

1st image is mouted to FDD1, 2nd image is mouted to FDD2.
(Not suitable when using only one FDD1 drive. Use NP2 menu.)
To swap FDD2 imagefile, libretro menu durling run core,
'Disk Control' -> 'Disk Cycle Tray Status' (eject) -> 'Disk Index' -> 'Disk Cycle Tray Status' (disk set)
So, to swap FDD1 imagefile, libretro 'Option' menu -> 'Swap Disks on Drive' set 'FDD1'

HDD/CD image can't be wiritten in .m3u file
You can write to .cmd file commandline,
(This file must be wiritten in UTF-8.)

np2kai fdilocation/aaa.fdi hdilocation/bbb.hdi isolocation/ccc.iso

'aaa.fdi' is mounted to FDD1,
'bbb.hdi' is mounted to HDD1,
'ccc.iso' is mounted to CD drive.
(Determined by extension)

.m3u files can written in .cmd file.
Then, You can FDs+HD and FDs+CD contents file.

Using mouse (J2M Joypad2Mouse)

Mouse cursor moving is always enable with mouse on PC.

Mouse cursor moving and left-button be able to controled with joypad stick.
Switch Stick2Mouse mode in config to 'L-stick' or 'R-stick(default)'.

• Stick: mouse move
  
• Thumb: mouse left button
  (if you need right-button, enable to J2M and use A button.)
  

To switch Joy2Mouse/Keyboard mode in config to 'Mouse'.
Mouse cursor is able to move with joypad's digital button also.

• D-UP/DOWN/LEFT/RIGHT: mouse move
  
• B button: mouse left button
  
• A button: mouse right button
  
• R button: mouse speed up durling hold
  

Using keyboard (J2K Joypad2Keyboard)

Keyboard is able to control with joypad.
Switch Joy2Mouse/Keyboard mode in config to 'Arrows' or 'Keypad' (or 'Manual').

• D-UP/DOWN/LEFT/RIGHT: Arrow key or Keypad(2468) key
  
• B button: Z key
  
• A button: X key
  
• X button: Space key
  
• Y button: left Ctrl key
  
• L button: Backspace key
  
• R button: right Shift key
  
• Select button: Escape key
  
• Start button: Return key
  

By setting Joy2Mouse/Keyboard mode to 'Manual', you can custom keycode for button.
Change 'lrjoybtn' value in system/np2kai/np2kai.cfg.
This value is little endian and 12 values ​​of 16bits(2Bytes) are arranged.
Write the key code of RETROK (see libretro.h) to this value.
The order is D-UP/DOWN/LEFT/RIGHT/A/B/X/Y/L/R/Select/Start.

Tuning performance

• CPU clock
  Change "CPU Clock Multiplyer".
  
• Memory size
  Change "RAM Size".
  
• Sound device
  26K: for old games.
  86: for newer games.
  
• Sound Generator (to change need reset)
  fmgen: fmgen sound generator.
  Default: NP2's default sound generator.
  
• How to set GDC 2.5MHz/5MHz?
  

1. Press End key(assigned Help key) + reset
   
2. Select 'ディップスイッチ２'(DIP switch 2)
   

• How to key typing?
  There are two ways:
  

1. map the 'enable hotkeys' hotkey in settings > input > input hotkey binds and RetroArch will stop listening for hotkeys unless/until you hold that button/key
   
2. enable the "game focus mode" (mapped to scroll_lock by default) and it will send all of your inputs to the core instead of the frontend. However, some people have reported having trouble getting out of game focus mode.

Informaion

Using CD-ROM drive

To use CD drive with MS-DOS 6.2,
write follow to CONFIG.SYS.

LASTDRIVE=Z
DEVICE=A:￥DOS￥NECCDD.SYS /D:CD_101

And write follow to AUTOEXEC.BAT.

A:￥DOS￥MSCDEX.EXE /D:CD_101 /L:Q

Then, you'll can use CD drive as Q drive.

How many files(0-15)?

This screen is boot as PC-98 ROM BASIC mode.
You succeed to locate BIOS files.
Your floppy/harddisk image isn't mount correctry.
Check selecting image files and restart.

About PC-9801 floppy disk image

NP2 is made according to PC-98 specifications.

Floppy disk types are 720KB(2DD) and 1.23MB(2HD).
The floppy drive differs from the one of the PC/AT on the hardware level.
(There are a few floppies formatted to 1.44MB(2HD) using MS-DOS 6.2.)

A common mistake is to create a floppy disk image with PC/AT.
Some disk imager for PC/AT software is useful, but can't use PC-98 formatted floppy disk.

To read data from PC-98 formatted floppy disk,
You must use Win2000 older and '3-mode' floppy disk drive.

Also, many PC-98 floppy disks are provided with powerful copy guard for DRM.
If you are in the way, you should use WIZARD V3/V5.
It is better to have no obstacle.

And also, you may simply convert the image format.

• vmdx
  
• vdi
  
• qcow
  
• qcow2
  
• hdd
  

Network Card

NP2kai can use NIC that is follow spec.

MELCO LGY-98
IRQ:6
I/O:0x00D0

WAB (Window Accelerator Boards)

NP2kai can use WAB (Window Accelerator Boards).

To use WAB, enable WAB in menu and restart.

WAB Type normally uses 'PC-9821Xe10,Xa7e,Xb10 built-in'.

640x480 256 color support for Windows 3.1

1. Switch to directory 'A:￥WINDOWS', then run 'SETUP' command.
   
2. Select display mode '640x480 256色 16ﾄﾞｯﾄ(9821ｼﾘｰｽﾞ対応)', or '640x480 256色 12ﾄﾞｯﾄ(9821ｼﾘｰｽﾞ対応)' for smaller system font, then complete the changes. You may need Windows 3.1 installation disks when applying changes for the display driver.
   
3. Extract 'EGCN4.DRV' and 'PEGCV8.DRV' from 'MINI3.CAB' in Windows 98 CD.
   
4. Copy extracted 'EGCN4.DRV' and 'PEGCV8.DRV' to 'A:￥WINDOWS￥SYSTEM' directory, so as to replace the original driver files from Windows 3.1 installation disk.
   
5. Type 'win' command to check if the driver works well.
   

NOTE: Do not run MS-DOS prompt with fullscreen mode, or your screen will get garbled when switching back to Windows environment.

You can use WAB Type 'WAB-S', 'WSN', 'GA-98NB'.

MIDI sound (X11)

External MIDI

NP2kai can use external MIDI sound generator with UM-1.

1. Connect UM-1 to USB
   
2. Check you can see 'C4D0' by '$ ls /dev/snd' command
   
3. Open xnp2kai
   

• Select xnp2kai's menu 'Device' -> 'MIDI option...'
  
• Set '/dev/snd/C4D0' to 'MIDI-OUT' in ’Device' frame
  
• Select 'MIDI-OUT device' to 'MIDI-OUT' in ’Assign' frame
  
• Press 'OK'
  

4. I tried with Touhou 2 (set MIDI option), I can listen MIDI sound.
   

Timidity++ (software MIDI synthesizer)

NP2kai can software synthesizer Timidity++ as Virtual MIDI.

It seems that Timidity++ is incompatible with PulseAudio.
By changing to ALSA output, I was able to play sound.

1. Install Timidity++ and fluid-soundfont-gm
   

$ sudo apt-get install timidity fluid-soundfont-gm

2. Edit timidity.cfg
   

$ sudo nano /etc/timidity

#source /etc/timidity/freepats.cfg<br>
source /etc/timidity/fluidr3_gm.cfg

3. restart timidity
   

$ sudo service timidity restart

$ aconnect -o

This time, you can see like Timidity port 128:0 to 128:3.
5.

$ timidity -iA -B2,8 -Os &

Run timidity daemon output to ALSA.

$ aconnect -o

This time, you can see like ALSAed Timidity port 129:0 to 129:3.
6.

$ sudo modprobe snd-virmidi

Add virtual MIDI port module.

$ aconnect -o

This time, you can see like VirMIDI 3-0 to 3-3 at 28:0 to 31:0.
7.

$ ls /dev/snd

You can also see VirMIDI 3-0 to 3-3 at midiC3D0 to midiC3D3.
8. Connect VirMIDI 3-0 and ALSAed Timidity port 0.

$ aconnect 28:0 129:0

9. Finally set '/dev/snd/midiC3D0' to xnp2kai.
   

Next boot computer, you command from 4.
