Why would anyone want this?
The controler was good enough for it's era, but once you use more modern versions and you go back, it's quite inferior and clunky. Also, drifting was super common, it's the console where I had most problems with the joysticks, even ahead of the PS2.
If anything, I'd like to use a Xbox One controller on my X360. (which is possible, but only with expensive usb adapters)
This.
All last X360 controllers produced had it, you switch physical aspect by rotating it.
Wasn't that good either, but better than anything.
I don't think it was all last X360 controllers, I have the last model, Xbox 360 E, and the controller it brought was the normal wireless one, without the rotating dpad.
