Using the Simple DirectMedia Layer on Atari
==============================================================================
==============================================================================
I. Building the Simple DirectMedia Layer libraries:
(This step isn't necessary if you have the SDL binary distribution)
Do the classic configure, with --disable-shared --enable-static and:
Tos version (should run everywhere):
--disable-threads
Tos does not support threads.
MiNT version (maybe Magic, only for multitasking OS):
--disable-pthreads --enable-pth
Mint and Magic may supports threads, so audio can be used with current
devices, like Sun audio, or disk-writing support. Like Tos, interrupt
audio without threads is more suited for Atari machines.
Then you can make ; make install it.
==============================================================================
II. Building the Simple DirectMedia Layer test programs:
Do the classic configure, then make.
Run them !
==============================================================================
III. Enjoy! :)
If you have a project you'd like me to know about, or want to ask questions,
go ahead and join the SDL developer's mailing list by sending e-mail to:
sdl-request@libsdl.org
and put "subscribe" into the subject of the message. Or alternatively you
can use the web interface:
http://www.libsdl.org/mailman/listinfo/sdl
==============================================================================
IV. What is supported:
Keyboard (GEMDOS, BIOS, GEM, Ikbd)
Mouse (XBIOS, GEM, Ikbd)
Video (XBIOS (Fullscreen), GEM (Windowed and Fullscreen))
Timer (VBL vector, GNU pth library)
Joysticks and joypads (Ikbd, Hardware)
Audio (Hardware, XBIOS, GSXB, MCSN, STFA, /dev/audio if threads enabled)
Threads (Multitasking OS only via GNU pth library)
Shared object loader (using LDG library from http://ldg.atari.org/)
Audio CD (MetaDOS)
OpenGL (using Mesa offscreen rendering driver)
- Driver combinations:
Video Kbd Mouse Timer Joysticks Joypads OpenGL
xbios ikbd ikbd vbl(2) ikbd hardware OSMesa
xbios gemdos xbios vbl(2) xbios hardware OSMesa
xbios bios xbios vbl(2) xbios hardware OSMesa
gem gem gem(1) vbl(2) xbios hardware no
(1) GEM does not report relative mouse motion, so xbios mouse driver is used
to report this type event.
(2) If you build SDL with threads using the GNU pth library, timers are
supported via the pth library.
==============================================================================
V. Environment variables:
SDL_VIDEODRIVER:
Set to 'xbios' to force xbios video driver
Set to 'gem' to force gem video driver
SDL_AUDIODRIVER:
Set to 'mint_gsxb' to force Atari GSXB audio driver
Set to 'mint_mcsn' to force Atari MCSN audio driver
Set to 'mint_stfa' to force Atari STFA audio driver
Set to 'mint_xbios' to force Atari Xbios audio driver
Set to 'mint_dma8' to force Atari 8 bits DMA audio driver
Set to 'audio' to force Sun /dev/audio audio driver
Set to 'disk' to force disk-writing audio driver
SDL_ATARI_EVENTSDRIVER
Set to 'ikbd' to force IKBD 6301 keyboard driver
Set to 'gemdos' to force gemdos keyboard driver
Set to 'bios' to force bios keyboard driver
SDL_JOYSTICK_ATARI:
Use any of these strings in the environment variable to enable or
disable a joystick:
'ikbd-joy1-[on|off]' for IKBD joystick on port 1 (hardware access)
'xbios-joy1-[on|off]' for IKBD joystick on port 1 (xbios access)
'porta-pad-[on|off]' for joypad on port A
'porta-joy0-[on|off]' for joystick 0 on port A
'porta-joy1-[on|off]' for joystick 1 on port A
'porta-lp-[on|off]' for lightpen on port A
'porta-anpad-[on|off]' for analog paddle on port A
'portb-pad-[on|off]' for joypad on port B
'portb-joy0-[on|off]' for joystick 0 on port B
'portb-joy1-[on|off]' for joystick 1 on port B
'portb-anpad-[on|off]' for analog paddle on port B
Default configuration is:
'ikbd-joy1-on' (if IKBD events driver enabled)
'xbios-joy1-on' (if gemdos/bios/gem events driver enabled)
'porta-pad-on portb-pad-on' (if available on the machine)
port[a|b]-[pad|joy?|lp|anpad]-* strings are mutually exclusives.
On such a port, you can only use a joypad OR 1 or 2 joysticks OR
a lightpen OR an analog paddle. You must disable joypad before
setting another controller.
The second joystick port on IKBD is used by the mouse, so not usable.
Descriptions of joysticks/joypads:
- Joypads: 1 hat, 17 buttons (Atari Jaguar console-like).
- Joysticks: 1 hat, 1 button.
- Lightpen, analog paddles: 2 axis, 2 buttons. The 2 buttons are those
affected to 1 button joysticks on the same port.

VI. More informations about drivers:
Xbios video:
Video chip is detected using the _VDO cookie.
Screen enhancers are not supported, but could be if you know how to
use them.
ST, STE, Mega ST, Mega STE:
320x200x4 bits, shades of grey, available only for the purpose
of testing SDL.
TT:
320x480x8 and 320x240x8 (software double-lined mode).
Falcon:
All modes supported by the current monitor (RVB or VGA).
Clones and any machine with monochrome monitor:
Not supported.
Gem video:
Automatically used if xbios not available.
All machines:
Only the current resolution, if 8 bits or higher depth.
IKBD keyboard, mouse and joystick driver:
Available if _MCH cookie is ST, Mega ST, STE, Mega STE, TT or Falcon.
Hades has an IKBD, but xbios is not available for video, so IKBD
driver is disabled.
Gemdos and bios keyboard driver:
Available on all machines.
Mouse and joystick xbios driver:
Available on all machines (I think).
Joypad driver:
Available if _MCH cookie is STE or Falcon.
PTH timer driver:
Available with multitasking OS.
VBL timer driver:
Available on all machines (I think).
Audio drivers:
Cookies _SND, MCSN, STFA and GSXB used to detect supported audio
capabilities.
STE, Mega STE, TT:
8 bits DMA (hardware access)
STFA, MCSN or GSXB driver if installed
Falcon:
8 bits DMA (hardware access)
Xbios functions
STFA, MCSN or GSXB driver if installed
Other machines:
STFA, MCSN or GSXB driver if installed
STFA driver:
