Sorry, the Adaptoid is a N64 controller to PC (via USB) interface. It's generally regarded as the best one because it supports all the features of the original controller (all control buttons, analog stick, rumble pack, and memory cartridge) without the use of any special drivers or calibration. It's truly plug and play. You can save games on your pc and run the N64 emulators and get to use the original controller. I use it for MAME as well. The cheaper N64 to USB adapters don't support force feedback and need a calibration routine to be run to use the analog stick. I'm not sure if the cheaper versions support the game saves to the hard drive. The adaptoid is also very compact - just a small dongle at the end of the cable, not a bulky box.
