What kind of PCB does it have, or have you not got the controller to gut? With a sony dual shock pcb, all the cheap 10 dollar Nyko PS>gc & xbox connectors work flawless with no button lag. I would tell you to use a ps1 dual shock controller regardless because of the ease to work with. They have huge solder points and can be done with ribbon hack without having to bother with the minor soldering at all. You can pick em up at gamestop for under 10 bucks and get a ps>xbox conver for just a few dollars more. If you don't want to solder, you can use this: http://home.comcast.net/~spiffyshoes/DualShockHack/
