==============================================================================
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-audio --disable-threads
Tos does not support threads, so can not support audio, maybe in a future
version audio support will be added via interrupts.
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, Ikbd)
Mouse (XBIOS, GEM, Ikbd)
Video (XBIOS (Fullscreen), GEM (Windowed and Fullscreen))
Timer (VBL vector)
Joystick and joypad support (Ikbd, Hardware)
- What is missing:
Audio support (TOS)
CDROM support (Metados, /dev/cdrom)
Threads support (TOS)
- Driver combinations:
Video Kbd Mouse Timer Jstick Joypads
xbios ikbd ikbd vbl ikbd hardware
xbios gemdos xbios vbl xbios hardware
xbios bios xbios vbl xbios hardware
gem gem gem vbl xbios hardware
==============================================================================
V. Environment variables:
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_VIDEODRIVER:
Set to 'xbios' to force xbios video driver
Set to 'gem' to force gem video 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.
Joypads are multibuttons controller (Atari Jaguar console-like).
Joysticks are 1 button, 2 axis controllers.
Lightpen and analog paddle are 2 buttons, 2 axis controllers. The 2
buttons are those affected to 1 button joysticks on the same port.
