I got some TTDS cards and I have problem with most of them. I load firmware and games to my micro sd kart then I open my ds. i can c the menü without any problem. after opening any game I have an error "THE GAME CARD HAS BEEN REMOVED. PLEASE POWER OFF YOUR DS AND REINSERT THE GAME CARD" I suppose I do something wrong. someone help me pls. Im telling every thing that I do step by step. I format my micro sd card as FAT32 I download firmware 1.16 from the site then I put it on to micro sd card. I put games on micro sd card. and I open my game. Must I do another thing?
