Thanks, but the codes for Pokethlon I'm asking for are actually to max your pokemon's performance, the Pokethlon stats of your pokemon. (Those stars) And somehow all the event pokemon codes don't work for me. Are they tested? My game doesn't start whenever I activate codes for event pokemon. I'm actually using an EDGE with a SS rom.
EDIT: The only event pokemon code working for me is the Manaphy Egg code.
