OT to this but it might be a better idea to make a faster way to approach this @Wiimm
A potential could be changing/NULling out the PID data perhaps so the game has to change FCs, stopping any overlaps that could occur if using AltWFC?
I currently host the DLS1, GAMESTATS, and Peerchat server for Wiimmfi. if you have any issues with leaderboards (excluding MKW!), Mystery Gifts or other in-game downloadables, or Pokémon Wi-Fi Plaza, I can try to help!
