I know they exist, and I know that the guy that makes them doesn't use too many parts (as can be seen in this picture. From what i've gleaned from the site and other various google results, this is only possible by using some sort of microcontroller that goes in between the controller and the computer (be it usb, serial, or parallel). Said microcontroller interprates the signals from the controller and then converts them (ideally) into HID compliant-ness, making for no drivers, and cross-platform compatibility. How doable is this for someone with a little bit of electronics (soldiering/programming microcontrollers/pushing buttons) experience? or should I unclench my 'cheeks and just buy a few of the kits?
