Having read Claudio's diary, I thought I'd give his modules a try.. Predictably, my poor player does indeed fail both. The S3M, I belive, fails because of an incorrect test for donness, jumping in and around the last order does that IIRC. Really simple fix. Neat song though. The MOD on the other hand.. Muse implements FastTracker stuff over ProTracker which of course screws it hard - they don't do jumps quite the same way, and I remember something about slides too being a tad different too.
It seems someone has been busy and fixed up MikMod this past year or two, the slink version wouldn't play either, but the potato version appears to get it OK. I wonder if anyone actually listens to modules anymore? At one point Muse was pretty damn good, it played everything, and at least for S3M, MTM, XM and IT/IT2 it was pretty much spot on. The rest of the formats (STM, WOW, FAR, 669, PTM and ULT) are OK for everything but the extremes. These days, I think, the new IT2s cannot be played (compression IIRC) and I imagine nobody writes anything but! I also never ported the GUS interface to linux. I really liked that bit of code too, sounded very sweet. Sad, bit rotted into obscurity :P
