The Ultimate Guide to MAME 0.119 ROMs: Preserving Arcade History

It had the parent ROMs, the clones, the bootlegs, the mahjong games no one understood, the obscure Japanese puzzle games with bizarre mechanics. It even had the gambling games with the blinking lights.

• MAME’s driver code changes frequently: device emulation, ROM loading rules, and merged/unmerged set handling shift between releases.
