I've been trying to figure out how to use Xbox 360 controllers to work on PS3 because i feel more comfortable holding 360 controllers. there was this method where you use a connector called XCM cross battle connector but as much as i want i don't want to spend money on that and.

You'll either have to spend money on that adapter and be stuck with Wired, or more money on someone to make a PS360 for you to be Wireless, or even more time and money on stuffing a PS3 controller in the 360 shell yourself, which can be done a couple of different ways.

Or you can do it the REALLY hard way:
Either:
Reverse-engineer the PS3 bluetooth connection, plug a wired xbox controller into a microcontroller controlling a bluetooth transmitter, and make it work,
Or:
Get a wired PS3 controller, reverse-engineer its protocol, reverse-engineer the wired XBOX 360 controller's protocol, and make it work

Honestly, if I had the time, I'd consider attempting this, but I'd rather not waste about a year of my life...

or, if you aren't that picky, you can try the feel of the batman PS3 controller...
