How exactly are you going to have a new FC soon? If you discovered a method to change it, I'd love to hear it. Hate the fact that my FC starts with "0920" (Hate zeros as the first or last number of the initial part of the FC)
new smilie ^
its much better than the rest (except for the fact that only touhou fans really understand it and im not a touhou fan and yes its bad apple thats like the testing thingy
)
Anyways, you can do change the FC without formatting with GodMode9.
