Well, i fixed it. I'm not sure what else i did but i ended up using the US eboot.bin in the EUR rip, then that made it so it could boot. However it'd freeze at the MK logo. Sooo i figured it was freezing because of either the ASSETS folder or the movie folder. Since there was no intro and it'd just freeze at the MK logo i assumed it was the movies.
I found the intro avis and meta data in the movies folder then replaced them with the US version, that allowed it to boot fine and i spent the evening playing versus mode with friends. But then the next day i tried story mode and it'd freeze at startup. I figured it was another avi problem so i just replaced the entire EUR MOVIES folder with the US folder and everything's worked great so far.
So i guess most of my problem was corrupt files or something, seeing as neither rip would work alone but when movies and eboot was switched out everything is great. Also if you happened to grab the US version off demonoid, at some point in the game it's going to freeze on story mode. That rip is missing a AVI file that the EUR version has, i'm not sure why.
excuse me for wall of text i'm blazed ^.^
