This card corrupts any SD card I put into it. The firmware is not upgradable. I got the latest kernel for it from the official site here. It looks exactly like the picture below only it is version 1.4.3. Is there anything that can be done to make this card work right? Is it defective? It works fine for a while, but after I save a few NDS games, the SD card becomes unreadable on any PC. Tried three different cards, formatted them all SLOW, using the SDFormatter application.
