I've tried it out and most games work...but for some odd reason super .Mario 64 ds doesn't? I've check and i have did everything correctly. Or unless I'm missing some steps for mario.
Are you near sea/salt water, or in general they just don't last. Sounds like if you driving a mercedes, you need a garage. I get snow n ice here so nothing worse than clearing that shit off at 6am rushing to get to work.
