Well you have the PAL version right?
It does not work on PAL unless you use the NCST version of Brawl (I am sure you know how to get it), and then download some things to bypass the region lock. Of course there is a lot more too it.
If you really want it you could find an online guide
Sorry, I was gone for a little while.
They have instructions on the main site for hackless
Oh I forgot,
They don't have a PAL version yet so I guess you will have to wait till they make one or learn to hack like a boss to bypass the region differences.
It's way better than Brawl. WAY BETTER.
Playing Project M makes you feel like Brawl was a broken game.
So much more tech skill, so much faster.

It's not just a hack. It is a masterpiece used in tournaments that was made by the most passionate people who decided to not let die competitive Smash. It does not matter if it's a hack or not, it is a polished Smash game.
