I took my m3i zero flash cart and updated it to the newest firmware for the 3ds firmware 3.0.5 and tested it in the DSi to make sure everything works. The system and sakura have also been updated. When I put it in the 3DS, it shows up as the chessmaster icon, but when I select it I get an error and it asks me to power down. I'm using a micro sd 8gb card. Any help would be great. Thanks.
