These are my Spanish gen I and gen II saves, but when I load them with PKHeX all of my pokemon appear to be in the Language: English instead of Spanish, I'm not sure if this has any relevancy on the PKM data but I wanted to point it
i checked my gen 3 and gen 4 saves and the language was fine, so I think it's only related to the first two generations
