I know this might be a bit of a long shot, but I figured I would give it a go;
I am trying to get Tyrian 2000 to work properly on my Steam Deck, via installing it from my gog library on Heroic. While it managed to install correctly I have a few issues that need to be resolved before I can continue;
The controller support is non-existent. I am unsure if that is fixable, though I suspect I might be able to get around it by remapping the Steam Deck controls. Not really a problem though if anybody knows a solution I’d be happy to hear it.
The real issue is that the music is not playing. Sound effects work just fine, so far, but I don’t get any music. I suspect it has something to do with Dosbox, given the age of the game in question.
As far as controls go, use the steam input to remap whatever controller you have to the games native keyboard inputs to your liking.
When it comes to dosbox, I’m not sure what you can do but I believe I read that steam has a native Linux platform for some of those older platforms like dosbox. Maybe that could alleviate the sound issues?
