Short: busywait-fixed ProTracker-replay Architecture: m68k-amigaos the old routine wasted about 2*10 rasterlines for switching the DMA off and on. this routine needs 2-8 lines for the dmawait (depending on the module). It was tested on an A500/A3000/A4000 and seems to play all modules ok (or at least the modules the original pt 1.1b replay plays ok). a very simple ProTracker-player for DeliTracker is included. BTW, using this new technique it should be no problem to fix the busywait-loops of almost every other replay ! known bugs: sometimes when a module starts playing and the first note is played on a channel, the routine needs ~100 rasterlines (in the mt_Wait2 loop). perhaps this is a dma problem ? if you know how to fix these bugs please contact me: kunath@informatik.tu-muenchen.de (Peter Kunath)
