In later MAME versions, a single game like Street Fighter II might be split into parent ROMs, clone ROMs, bootlegs, and region variants. Version 0.139 sits in a happy middle ground: it supports all major variants, but the naming and file structure are far less intimidating for a beginner.
Hey everyone,
Ask any veteran emulator user about "missing ROMs" or "incorrect checksums." With 0.139, the ROMsets were largely finalized for major titles like Donkey Kong , Pac-Man , Galaga , and Neo Geo games. If you have a complete 0.139 set, you have a library of over 7,000 unique games that just work without endless fiddling.
