Damn thing was a sod to get to do in the first place... I remember that the playback MUST be frameskip 0 - no autoframeskip & change once running - it had to frameskip 0 from the command line. Have you tried with / without sound?
yeah all ways crap out at 1k, in 98 and xp too, still could be the 63 thing. need a 3rd or buttermaker's 63 stamp of acceptance, and your entry into set B.
