Many software is wrote in Windows only programming software.
My own software, MultiJuke, is wrote in Blitzmax which is also exists to Linux as well.
One of the future version, but have no date yet, I hope I can trying to convert it to Linux as well. For some weeks ago I tried PCLinuxOS without luck, but would soon try Ubuntu 5.1, which is the officiel recommered version to compile under.
I also hope I can get FMOD to work on Linux, but I did not use that on Windows version, so I need to change some code as well. It only sound thing to redirect to FMOS I need to change. I could also use BlitzMax soundEngine, but it only support WAV and OGG, not MP3 (Due to patents), which is normally fine in games.
I cant see the date yet, if it in days or weeks or such. But it a goal to get MultiJuke to work on Linux...
