I bought a Supercard DS One SDHC several months ago and used it primarily for Homebrew stuff. We took a car trip to my relatives for new years, and I decided to load a bunch of my DS games onto my SD card so I didn't have to keep track of all the games. My problem is that games freeze up all the time. For example, Yoshi's Island DS freezes whenever I go through a door, Final Fantasy IV freezes whenever I win a battle, and Custom Robo Arena freezes whenever I start a battle. I'm using a Sandisc 8gb class 6 (40x) micro sdhc card. I ran the self test and it didn't find any problems. There was 1 day during the trip where it didn't freeze at all, but now it is freezing again. It has no problems doing homebrew stuff, but I figure it must be a bad Supercard. Any suggestions would be greatly appreciated.
