GUIDES / SYSTEMS

Systems

All 21 systems: the folder, the file types, the emulator, the BIOS files they can use, and what each cabinet button does.

Buttons are written as CABINET console button. They're the defaults; change them for one game or a whole system with Home > Controls (see Controls & settings). Settings > BIOS check shows which BIOS files you have and where missing ones go.
