that's good stuff thx

Alright, thanks guys. Will start working on this as soon as i get my logic analyser.

I see, do you know if anyone has ever completed one of these? I think i will be using an stm32f (cortex M4) since i already have one at my disposition even though it might be overkill. And do you think bitbanging is the way to go for data transfer?

Was just wondering if anyone has ever attempted to make a gamecube controller emulator. If so, was it with an fpga or a microcontroller (or both)? I'm thinking of making one myself but dealing with nintendo's weird protocol looks like it's going to be pain.
