Multithreading games support

[TkSilver]

Natively no psp game supports multi-threading since the psp itself is a single core system.

As far as the option in ppsspp goes the best advice is to simply turn it on and see if anything messes up, and if something does turn it off. (Though this advice is useful for all speed hacks and experimental features too) There is no list that I know of, because the emulator and your specific setup (android/pc, intel/amd/qualcom/samsung, ect., ect.) will have an effect on how well those options work for you.
