No it is not a long track. I never did particularly long tracks. Mostly looping ones with a few blocks and no more than 2 rows of track data.
I have now saved the track from FC 2.1, converted it to SID, used PSID64 to convert that into a executable PRG, and loaded that into VICE and ran it. Same broken music.
I also tried to save+relocate to $1000.
I have no real C64 set up right now. It's all packed down. That would be the next step I think.

This is the file http://madmodders.se/temp/c64/problematic.prg
Uhm, no. hold on. that did not load at all...
[edit2]
Now, it's the right file. Try it if you have the time.
