The tool can't detect that my European English Pokémon Emerald save is English, I know for sure it's legit as it's from a cartridge I dumped and checked the MD5 with the no intro database. It is not really a big problem of course but I thought I would report it.

A bigger problem is that my European English Pokémon Ruby R2 save (also from my own cartridge and checked with the no intro database) is detected as a Emerald save.

The same problem occurs with my US English Pokémon Sapphire R2 save (also from my own cartridge and checked with the no intro database).
