I'm sorry to hear that you have issues. I have tested it a lot with various configs and no issues. I suggest to reach out at EAB at post screenshots of the corruptions for instance. And maybe a video for the speed?
The fruit should be 2x slower than pacman. And after a while the game IS fast.
What to do next? I don't know. Perfect arcade ports are difficult. I'd go for Amidar or Phoenix, or Time Pilot.
