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. + Milan: + Experimental support + 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.
