Maybe some files or plugins are corrupt with the emulator somehow, or some settings are configured oddly somehow? Maybe you can try reinstalling the emulator.
Maybe some hardware drivers are having some trouble... but I guess not if other games are working OK.
Are you playing from an external drive that is causing hiccups maybe? Slow drive?
ISOs could have been corrupted possibly I guess, but doesn't sound like it's this, I'd say this is unlikely.
Also I guess a common suggestion is restart the computer if it hasn't been done in a while
Just ideas, I'm not sure what the problem is either, sounds troublesome.
