I don't even wanna mess with the over clocking. There's always a risk of overheating your device and no way I would take that risk. I'm just gonna leave it at stock clock at all times. So far I've tested Mario 64 and killer instinct. Mario 64 does run at full speed most of the time but sometimes I noticed it lags. For killer instinct I was only able to get to the character select screen and after that retroarch crashes. Hopefully by the time the stable version comes out that it will fix all issues.
