That's life. It wasn't working properly before, and this was causing random flickering and other problems and crashes.

If you expect synchronization in emulators to result in ultra-high speed, go try bsnes.

Multithreading meaning of existence is speed up? Now just let the game run more slowly, is not no sense.Desirable to increase an option to cancel this code.@sum2012 @unknownbrackets @hrydgard
