I have proudly finished my first midibox sid (just 1core+1sid) and wanted to play sid files. Unfortunately ASID XP didn't work on my win2k-machine and sidplayer showed the behavior that was mentioned before. but i wanted to hear definetly my favourite c64-song ;) So I did a small workaround: installed midiyoke and midiox to have virtual midiports played the file in sidplayer recorded sysex messages in midiox set the "delay after f7" down to 8ms played the recorded sysex messages This method is not very effective, but it was the only way for me, to get a nice playback. Now I have a new fileformat for c64-songs: .syx I'm so happy with my fresh midibox, i never want to switch it off again ;D
