[edit] gfx

gfx backends provide the graphics and user-input. The graphics backend is always the first named, for example, ohrrpgce-wip-gfx-music.zip

name	status	description	fullscreen	smoothing
gfx_fb	stable	Freebasic graphics. This backend is well-tested, and is used as the default	Windows:Yes Linux:Maybe	Optional
gfx_sdl	working	Simple DirectMedia Layer (SDL) graphics. Working well, only a few issues	Yes	No
gfx_alleg	working, but very little testing	Allegro backend.	Yes	No
gfx_directx (name?)	experimental	Windows-only Directx background. Not presently in subversion	??	??

[edit] music

music backends provide the music and sound effects. The music backend is always the second named, for example, ohrrpgce-wip-gfx-music.zip

name	status	description	advanced MIDI looping
music_native	Windows:stable Linux:experimental	Audiere and Native windows midi. On Linux, this backend uses timidity for MIDI.	Windows:Yes Linux:No
music_sdl	stable	SDL backend. This is the default on both Windows and Linux (May have problems on Windows Vista. More testing desired)	No
music_allegro	obsolete	Allegro backend. Unmaintained; no longer works or even compiles. Only worked together with gfx_alleg	No
music_native2	experimental, seems to be working	(Windows-only) music_native variant with alternative, "better", MIDI implementation. Identical Audiere sound effects implementation	Controller 111 loop points only
music_silence	diagnostic	Does not play any music or sound at all. Useful for checking whether or not a bug is related to music.	No

name	status	description
-debug	diagnostic	Any nightly build with -debug in the filename has been compiled with -g which adds debugging symbols for use with the GNU Debugger
-exx	diagnostic	Any nightly build with -exx in the filename has been compiled with -exx which adds extra error checking for out-of-bounds array access and null pointer dereferencing. These builds are many times slower, something which might be noticeable on very old computers.
-scriptprofile	diagnostic	Any nightly build with -profile in the filename has been compiled with -d SCRIPTPROFILE to perform script profiling; when you exit a game, Game prints a whole lot of statistics to g_debug.txt about how much time each script took to run.
