works perfectly with vice.

Exact same problem on MEGA65 c64 core.
The screen gets black after Steffan image, but the music keeps playing so indeed really strange.

It continues after ~21 minutes, which is about $FFFF number of frames. I guess the delay counter is initialized wrongly from somewhere, or depends on uninitialised values in RAM. Same happens even in recent x64sc, right after the beginning.
