Mayflash Gamecube Adapter Controller Problems

[Bossmanjay]

Hello,
I've read some threads about controller issues with the Mayflash Gamecube Controller adapter for MAC OS X,
but im still not able figure out how to get it so I can play multiplayer games.
I always manage to configure the controller,
but the controller connected to pad 1 always ends up
controlling the rest of the controllers.
