Okay first of all i just got my M3 Real yesterday. I'm kind of a noob. And for some reason every rom i have gives me bugs and horrible glitches. at first i thot it was the website i was downloading from (romulation) so then i tried a new site (nds-roms) and the games still all have bugs and freeze and stuff. especially with the world ends with you, it always freezes at the same part. is it my m3 cart, my sandisk 4gb microsd? do i need to re download the firmware? please please help
