I've just released a translation patch for the Game Boy Color game Harry Potter 3. so, if for some reason you ever wanted to play this thing with its small amount of text translated into English.. enjoy! if you notice any bugs or anything (except the palette issues mentioned in the readme, which were in the original) let me know.
well its a Game Boy game, FCEU is a NES emulator.. unless i'm missing something, I wouldn't expect it to work.
