One of the most difficult things to play MK are the various movements and buttons that must be pressed sequentially to release a simple combo.
And more, you need to memorize them all...
Thinking on it, I decided to modify my PS3 dual-shock controller, and add a special button.
A macro-key button ! Just press it once, and a super sequence of combos is released against your opponent.
Don't use it to promote yourself, ok ? This is something you should only use to cheat your friends ;-) sometimes worth kidding.
In fact what I did was hacking the controller and not the game. So yes, you can apply this project to any other PS3 game.
