Xbox 360 Rapid Fire Trigger Mod

I love to play my Xbox 360, but I needed a little edge over the people that spend all day and night playing. Because I have to work during the day, I can’t do that.

So I wrote some code in PicBasic for a PIC12F683. The basic code is below, you are welcome to use it, you will need to compile it to a HEX file and flash it to the chip. It comes with NO warranty’s. This mod may not work with all controllers, but it worked for me!

Once installed you use a quick press of the sync button to toggle the mod off and on. The mod is indicated by the lower left quadrant LED of the controller.
