Do any of you guys remember what kind of music is supported? I know some of them are .Mod, .S3M, .It, .Xm, .669... Uh, any others?

I am asking because I have some ".IMF" (MIDI Files coded by Apogee) files I extracted from Duke Nukem 2. I needed to download a plugin for winamp to play them. I was wondering if these can play in jj2?
