This is 1992-ish production, so it _could_ be stored on some BBS dump (music oriented or something).
Or maybe asking B.A.D again ?
I'm very curious about the music system in these disks, myself. If you know how to contact him, maybe you could ask how he actually composed the musics. The samples are replaced live in memory, for obvious memory size reason. How he ended up being able to actually compose a music with samples that are not fixed ? that's a mystery
Anyway, if you happen to locate other TEF material, please tell me
