if you're on emulator, try removing the first line. other than that, i don't know why it's not working.
you could use the moveset modifier to give him one of Sora's keyblades and that will allow him to beat the bosses. but it's not really a good code because it causes a lot of Mickey's attacks to not connect when they should.
1. probably, but no one really tries hacking gummi codes.
2. i tried to hack this a long time ago but failed
3. tried this one too but failed as well.
things are looking pretty good for this game! i'm disappointed by the Wii U release date though. i hope it's because they're cooking up something awesome for that version. because i do like the 3DS Smash Run exclusive part. i'm hoping they're making something just as a cool for the console version.
and Greninja is an unexpected addition to the game. it's a welcome one for me though.
that was a pretty interesting trailer. the anime scenes makes me think this is more like Generations rather than Storm 3. does anyone know the release date? it was in Japanese in the trailer, i know it's not the English release date, but still.
try activating the code from a different room. a lot of people have much better luck with activating the code going from the Throne Room in Disney Castle going into the Hall of the Cornerstone.
