I think it would be a super easy mod, just replace super 17 with Yamchas model, i was trying to edit the cms file to do just that but i messed my whole game up. : / I don’t know if anyone will bother with this request because its not as complex as a new character from HEROES or something like that but I thought I would try.
Universe 9 Videl with kaioken would also be cool but would require someone to make the outfit and give her a sword.
Universe 9 Characters originate from a fan comic called Dragon Ball Multiverse in case anyone is confused. Someone just recently created an awesome Krillen Universe 9 mod
