I use the Gamecube controller for the GB Player. I'm not that comfortable with it, but thats my only gripe.[/quote]
That's true, it's kind of weird using the L/R or X/Y on the GC controllers in replacement of the GBA L/R, especially if you've been using the GBA already. It's not too bad though, and plus you could always import a Hori controller if it bugs you enough.
