I want to make a joystick using arcade parts (Competition Joystick & buttons) with the original (arcade) Mortal Kombat button layout for use in MAME mostly.
Beeing a big MK fan I don't want to be restricted in playing my (future) joystick only on the PC.
I'm planning on buying a 3-in-1 adapter for the PS2 wich makes it possible to play a Dualshock 2 on a PC , GameCube and on the Xbox.
The 'Hack' is meant to hotwire the PS2 Dualschock 2 so you can connect the arcade joystick & buttons to it.

Anyone knows if this is possible and or hard to do ?
