The MVS and AES hardware can execute identical machine code. Owners can move EPROMs from one type to the other, and the game will still run. The program specifics for both MVS and AES game options are contained on every game ROM, whether the cartridge is intended for home or arcade use. However, the arcade and home cartridges do have a different pinout. They were designed this way to prevent arcade operators from buying the cheaper home carts and then using them in arcades. It has been found that in a few home version games, one could unlock the arcade version of the game by inputting a special code.
