Just recently with Batman Brave and the Bold, my DS turns off during the first minute of gameplay. I thought it was a bad file so I tried Spiderman Shattered Dimensions and I get the same thing. My older games like Picross 3D still work fine. I am using a Cyclo Ds flash cart and a 2 GB SanDisk SD card. Any help would be appreciated. I've read a little about the Universal Game patch but I am unfamiliar with it. Any suggestions.
