I've started to have getting random freezes (around 30min-1hr apart) in all games. At first I thought it was just a problem with Ghost Trick, but now it happens on all the games I've tried, including those that used to work fine. I've been using the same kingston 1gb micro sd card (and the same ds-lite) for like 2 years without this issue until now. It seems short of some weird issue after updating my firmware that no one else is having, that either my flashcart or my microsd is crapping out. Is there an easy way to check if there's anything wrong with the microsd via pc?
