hi i have bought a dstt card and a sd card and have dragged and dropped games onto the memory card but when i put it in my ds it just says menu and wont load. i have formatted the sd card using fat 32, but i have heard that i may need to download ttmenu onto the sd card to make it work. is this right and if so what exactly do i need to download and where can i download it from. im not very clever with these gadgets so could someone please help me with step by step details. thanks, julie.
