All files I have are running. I can't 100% confirm for Gen4 since I'm still using the stock files i got before, but Gen 5 has all event files from projectpokemon in all languages running.
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!
