Homebrew coders over at TehSkeen have manged the near-ultimate hacker achievement of enabling region-free gaming on the Wii via a software hack -- no mod chips or Freeloader
disc required. Implementation of Gecko Region Free couldn't be simpler: you just load boot.elf from the chain loader, stick in your Wii game and hit reset. The hack claims to have borrowed zero code from Nintendo or Datel, making this pure homebrew. You'll still need to use that Twilight Princess hack to get thing started, and Nintendo could always rain on this parade, but for the time being the world (of foreign-released games) is your oyster.
