When you look for a MAME ROM index, you will quickly notice that sets are organized by version numbers, such as 0.264 or 0.139. It is crucial to match your ROM set version to your MAME emulator version. Unlike modern software, MAME ROMs are frequently updated or re-dumped to improve accuracy. If you try to run an older ROM set on a newer version of MAME, you may encounter "missing file" errors because the naming conventions or required data files have changed. index of mame roms
