There are very few instances where you actually get to test something before it comes out, and with nintendo's ridiculous download stations showing old demos for games you can actually go out and buy it doesn't make much sense. Really though i stumbled across this demo while looking for something else, and the game is just about as good as they say it is. I have tested it on my m3 cf of course, and it's working fine....im not even sure it needs to be on 4x even though i selected that just i case.
