With some creative homebrew and PC emulator work, I've managed to create a fresh Virtual Console save that has all the GBC courts unlocked, as well as all four GBC characters (using default names) transferred into the game. I've submitted the save to GameFAQs and it should be up soon.
And before anyone asks, yes, the VC release actually contains all Transfer Pak related things, and they work just fine. --- It's weak to light. Shine on! XBL/PSN: Pika025 | http://backloggery.com/pikachu025/sig.gif
