@Shadow666 Everything runs slowly and the sound is very choppy with recalbox? Surely it can't be throttling the cpu
What games are you running? Everything runs great bar N64 atm with the 9.2 release on the site. If you have a patreon account you can get the latest beta where n64 runs better. They even have killer instint arcade version at full speed with Mame 2003.
I tested fbneo and they seem to be running a very old core, they are missing a lot of features which are on the official build.
Recalbox support seems to be focused on French which is a pain as it is not a language I am good at.
