The question is not about profiling, but about the OPL emulators
taking up too much CPU time in general with -O0 on the PSP (with
profiling) and thus resulting in such glitches anyway. Thus it would
be nice if you could try another game engine with -O0 and profiling
enabled and test whether the sound/graphics output suffers from the
same problems.
