*caps........ :( *clean the contact part of the cart with a cutip to get the dirt off of it. this helped me when i wanted to play some sega genesis games. just make sure not to press that hard on it though or you may brake it...then blow (not spit) into the ds slot to ensure that there isn't any dust or dirt in there too.

Do not use all caps please. Make sure you have the latest firmware http://linfoxdomain.com/ds/
