My roommate and I recently started playing Pokemon Stadium through Project64, and are using GB pokemon saves created on VBA with it. The topic came up of Stadium sequels and I remembered they made something like that, Pokemon Colosseum. What I'd like us to be able to do is emulate the game in Dolphin, and somehow link it to GBA saves the same way we're doing with PJ64. However, I see that it normally also requires you use actual GBAs with the gamecube cables. Is there a workaround for this that would allow us to do it all through emulation?

If this isn't possible I do have a modded, gamecube compatible wii, with plenty of gamecube controllers and at least two GBA SPs with the cables. While not what I'd prefer, I'm sure I could make do with doing it this way if possible.
