I've been searching around trying to find out a way of playing my XBox emulators with authentic gamepads/joystick, especially the Megadrive and Amiga. They both use DB9 connectors. I found a thread on how to hack an XBox controller with a DB9 port but the links are long dead - then I came across this:USB Retropad Adaptor
Anyone know if it's any good? It seems like it supports the original XBox and looks too good to be true!
