Okay what the fuck. I was willing to put up with the random freezes, so I played the game, saving whenever I got the chance. It was going ok (with a few random freezes every now and then) until I beat the first sister (by herself). I went to save my game, then I went into the menu to equip things (like I normally do after save). After leaving the menu, the game froze. No big deal, I was used to it. So I turn off the DS and back on. Hey what do you know.......SAVE FILE CORRUPTED! This is the first time I got a corrupt save file after a freeze. I give up. I was willing to deal with the freezes, but I'm definitely NOT willing to deal with two hours of game time lost. Good bye.
If it still does this shit after I buy the legit version (as I've seen happen with some people), I'm demanding my money back, regardless of return policy. Konami just plain sucks for releasing a buggy legit game.
