Hi, I am very very new to the wonderful world of NES emulation, AND I LOVE IT. kicking a$$ on mike tyson, and i havent been in training for over a decade. my shift and option keys are getting a pounding, so i need to find a USB controller. any recommendations? I have seen these SNES original controllers with USB, will they work with both NES and SNES emulation (I imagine you just calibrate A B only ...) or are there other non-original cheap usb pads that are easy to find. and how does one find games? this is only a borrowed powerbook and has jsut a few game on it. i want to add this to my mbp in the fall. i feel 12 again.
