With all the hard that has been put in, we now have a fully compatible list of cores for Retroarch.
- NES: QuickNES
- SNES: Snes9x 2010
- MegaDrive/Genesis: picodrive
- Game Boy/Game Boy Color: Gambatte
- Game Boy Advance: mGBA and VBA-M
- PC Engine: Beetle PCE Fast
Make sure you have updated all of these cores and RetroArch from source from within the retropie setup script.
If you do come across and problems please get a save state just before the achievement unlocks and upload it to this github. If you don’t have github account post a link to your save state with information on what game and achievement each save state is for. Also what core you are using in the comments and I will upload it for you.
