Using RAW didn't work for me so I used a different method:
1. Use ARv1 as the input
2. Make sure you have the game id set as '0001'
3.Make sure the region is set to Japan
4. Output as codebreaker
It worked for me with AR MAX, so I don't know if codebreaker is different.
Hey EvilMan, I'm testing the code now. I'll edit this post if it does or doesn't work.
EDIT: Sorry EvilMan, but it didn't work, it would have been fun to play as Mickey in all worlds, but I haven't checked every world so it might work in one of them.
EDIT(2): I just checked every world and it didn't work, too bad.
