I asked this in the 5th gen shiny thread, but didn't get an answer:
Does a pokemon's name being in japanese characters guarentee it will work for MMing? I didn't know if english hacks could do that.
i cant imagine the pokemon's name to be Japanese, if the OT name is english. look closely though, if the letters in the OT name (in English) are larger than standard english letters - which you can compare to anything you catch yourself, then it is from the Japanese games and viable to work with MM.
