From your description this would appear to be due to the fact that when the
emulator is running compiled code, it's less friendly to the custom-chip
emulation. By 'less friendly' I mean that there's a greater latency in
handling custom-chip events - hence the audio drop outs. Does increasing the
size of the audio buffer reduce the problem?
When the emulator is presented with new code, it's interpreted several times
before it's compiled (this is a hot-spot kind of thing - only code that is
used several times is actually compiled) and the interpretive emulator is
much more accomodating to the custom-chip emulation.
I don't have a solution for this as yet. I need to study in more detail how
the custom-chip emulator meshes with the JIT...
Cheers,
Rich
