Back up your save states before your first launch. Some older save states are incompatible with the ARM64 cores and will crash if loaded. The app will warn you and let you choose — but it's safest to have a backup ready. Run this first:

cp -R ~/Library/Application\ Support/OpenEmu/Save\ States/ ~/Desktop/OpenEmu-Save-States-Backup/
