How to play midis in new engines for games

Software
1

For example we can play Space Cadet in Haiku, compiling this engine

But the music is missing, the effects are wav pcm.

We need to install two programs

-Timidity and timidity_freepats

Then create a folder in /etc called timidity [/etc/timidity/] copy all the data from

/boot/system/data/midi/freepats/
to
/etc/timidity/

This method works too in the engine for the game Bermuda Syndrome

Did you try export SDL_SOUNDFONT=/path/to/your/soundfont before launching the game like explained here?

Yes, i did it, the problem is the sdl2 mixer looks for this path (source code sdl2_mixer, file music_timidity.c line 52)

SDL Error: Couldn’t open /etc/timidity/freepats.cfg

Dirty solution is copying the files there and looks solves the problem, other solution is modify the source code of src/codecs/music_timidity.c

define TIMIDITY_CFG_ETC “/boot/system/data/midi/freepats/timidity.cfg”

define TIMIDITY_CFG_FREEPATS “/boot/system/data/midi/freepats/freepats.cfg”

#endif

I compiled and created an hpkg and the solution works
