The 2 buttons are those - affected to 1 button joysticks on the same port. - -============================================================================== -VI. More informations about drivers: - -OpenGL: - The default is to use the Mesa offscreen driver (osmesa.ldg). If you want - to use an older OpenGL implementation, like mesa_gl.ldg or tiny_gl.ldg, - your program must use SDL_GL_LoadLibrary() to do so, and retrieve the - needed function pointers with SDL_LoadFunction(). In all cases, the OpenGL - context is taken care of by SDL itself, you just have to use gl* functions. - - However, there is one OpenGL call that has a different prototype in the old - implementations: glOrtho(). In the old implementations, it has 6 float as - parameters, in the standard one, it has 6 double parameters. If you want - to compile testdyngl, or any other SDL program that loads its OpenGL - library, you must change the glOrtho() prototype used in this program. In - osmesa.ldg, you can retrieve a glOrtho() with double parameters, by - searching for the function "glOrtho6d". - -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). - BlowUp and Centscreen extended modes, ScreenBlaster 3 current mode. - 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: - http://removers.free.fr/softs/stfa.html - GSXB driver: - http://assemsoft.atari.org/gsxb/ - MacSound driver: - http://jf.omnis.ch/software/tos/ - MagicSound driver (MCSN,GSXB compatible): - http://perso.wanadoo.fr/didierm/ - X-Sound driver (GSXB compatible): - http://www.uni-ulm.de/~s_thuth/atari/xsound_e.html - --- -Patrice Mandin <pmandin@caramail.com> -http://pmandin.atari.org/
