A: Start a HUGE translation project with the game. If it's popular enough, it might get some volunteers :P
B: Goto Gamefaqs website, they usually have translations for every game, I found translations for Quedan, AND Jump Super Stars and Jump Ultimate Stars
C: Be friends with a random Asian and ask him if he/she can translate. If you don't get punched/kicked in the stomach, then high chance that person will translate OR doesnt know how to :P XD ( I better not hear any bs cuz of my post :P, you all know I don't think EVERY asian talks japanese/chinese, and I'm in too much of a bad mood to have someone kill my post with something pointless that will only result in a waste of time
)
