@terry @maddy This page mentions that installing Windows is not necessary: https://www.thegamebinc.com/blog/launching-the-an-untitled-story-restoration-project
It says that MIDI isn't supported "on non-Windows platforms", but that's absolutely not true - I even had it working under Wine with my own ancient TGF games, it just needs to be configured correctly in ALSA. I may take a look at that later.
@dos oh, did you actually get it working? I tried a few different wine versions and none of them had music 😔 you should put something online for the next person who searches, this would have saved me a bunch of work!
@terry Looks like the issue is not about MIDI support in general like that article makes it seem, but with the API GameMaker used (DirectMusic) having a very incomplete implementation in Wine. May still be possible to get it to work via native Windows dlls.
Other than that, it needs timidity and a soundfont to be installed on Deck and running in ALSA sequencer mode. I just tested MIDI in a TGF game and it works on Deck after doing that. So it's just DirectMusic that still needs to be tackled.
