I couldn't find any solution in the Internet so I'll present my problem here. I'm about 30 hours in the game and yesterday, after after beating N and Ghetsis and starting over at Nuvema I have done some fishing with my super rod and the game sterted to freeze at any battle's start or even wild pokemon encouter. When its an encouter it freezes giving two white screens but odd enough the music keeps playing and before a battle with someone in the game, that someone approach me and nothing, screen freezes without music. NOTE: I'm using legit ak2i with latest AKAIO on legit Kingston SDHC 4GB. I'm playing on DSi XL, I haven't experienced any problems other than that. I wanted to do some post-game but no luck. Also never used codes.
