Oh yeah, PCEjin, I had forgotten the name of that one. Anyways, it might be a problem with Garner's original code. It'll likely be swapped out for Squirrel soon anyways, since Arkhan's new development version is supposed to support sound effects. But I'll check it out with PCEjin too.
EDIT: PCEjin is a f*cking moron. I gave it the cuesheet to load, and instead of loading track02.iso like the cuesheet instructs, it tries to load monolith.bin. That file isn't anywhere in the cuesheet. Stupid program doesn't even know how to follow simple f*cking directions.
EDIT2: Its framerate is pathetic too. But I took notice of the sound delay there as well. Then again, that could simply be because its performance is so poor.
EDIT3: It is most definitely an emulator problem. I just tested in it Hu-Go! which, despite having some of the worst sound emulation ever, does not have the problem.
