Arcade ROMs are not like console ROMs. A single arcade game consists of multiple chips (dumped as separate files) packed into one zip file. If even one byte of a sound chip or graphics chip is missing or corrupted, the game will crash. A verified set guarantees and absolute compatibility with the MAME 0.84 executable.
