I've been through that line of questioning before. You'd need a driver. I haven't found a serial driver for it, ever, and never got the generic pad stuff in windows to recognize it. You can build a serial-parallel interface for it and use it on the printer (LPT) port with some-or-another driver that I can't remember the name of. I wasn't really interested in doing that since I kind of use the LPT port. If it wasn't 20 bucks I don't have, I'd get that Magic Box converter and use one of my Saturn controllers on a USB port. However, I've heard that it doesn't support the analog stick on the 3d controllers, which kinda sucks. Even so, saturn pads would be great for a lot of emulators! Probably my favorite controller overall, if the DC controller had 2 more face buttons and used the Saturn's d-pad instead of its own (but still had the DC analog), then the DC pad would be ultimate. Whoa, im off track now...
