The fast-forward/turbo button works fine when in unbounded mode, but when set to 5x or some other bounded amount the sound fast forwards and the graphics do not. Found when testing the 0.8 beta 1 preview. I was testing out GB/GBC games, but I just checked with a GBA game and it behaved the same. (Pokemon Yellow/Silver and Fire Emblem Sacred Stones if you need this info). I'm on Windows 10.

I forgot to ask, do you have sync to video enabled?

No. I had sync to audio enabled because it (at least used to) help with gb/gbc link cable connections according to comments on another issue. Turning on sync to video doesn't help with this issue and turning off both makes the game run in unbounded speed up mode all the time.

It's fixed but the fix hasn't made it to a released version yet.

Can I fix the problem myself? When does the release come in which the problem is fixed?
