The is more than just a collection of ZIP files. It is a time capsule of arcade emulation at its peak accessibility. While modern MAME v0.250+ offers marginally better accuracy for obscure protection chips and laserdisc games, it does so at the cost of complexity, storage, and processing power.
A "ROMs Archive" for a specific MAME version is a complete or near-complete collection of game ROM images that are verified to work with that exact version of the emulator.
