Find Known ROMs

Look for known ROM dumps in a directory, matched against a ClrMamePro data file.

$ find-known-roms "~/Downloads/Sega Ages 2500 Series Vol. 33 - Fantasy Zone Complete Collection"

Requirements

• lfs (called lua-filesystem in Fedora)
• lua-posix
• lua-amalg (to create the stand-alone binary)

And a directory containing ROM .dat files in the ClrMamePro format, such as a checkout of libretro-database, or any other compatible .dat files. Install the .dat files you're interested in in the ~/.local/share/find-known-roms/ directory if you want to avoid having to pass a path each time.

You would however be well advised to pick .dat files that are interesting to you, as libretro-database's full set takes a long long while to parse. All depends on your use.

Running

Look for ROMs in /path/to/possible/roms using databases in /path/to/databases:

$ find-known-roms /path/to/possible/roms /path/to/databases

Look for ROMs in /path/to/possible/roms with databases installed in ~/.local/share/find-known-roms/:

$ find-known-roms /path/to/possible/roms

Look for ROMs in the current directory with databases installed in ~/.local/share/find-known-roms/:

$ find-known-roms

Limitations

Only supports the ClrMamePro format. Other formats exist, so supporting them might be nice. Send patches.

Uses

This was used to find 30 hidden games in one Sega Ages 2500 compilation.
