While looking on how to add composite ports to a Genesis, I found this site:
http://zero.navi.cx/gallery/v/hardware/genesis-mod/
There's no text on the page, just an image gallery, but they added a usb port to a genesis. How cool At first I thought they were going to use it to load roms from a hard drive or something, but I think they're just using it to use usb gamepads with it. Has anyone seen anything like this before?
