well, there is someone who works on this, he wants to give us a good and practical build, we must have patience. the build is coming but we mustn stress the programmer. till then we can find a practical maping of the buttons, and the easiest way i see is to make a list with the most played gamecube games, (personally i think mario kart double dash is the first) and find a way to ergonomically distribute tha maping to easily play those games.
