I don't know why this is so confusing for me because I've been able to open up the the .nds launcher before in the GW fake RPG game. I've hacked all my other portable devices but between all this new stuff like NAND EMUNAND SYSNAND etc I could really use some step by step instructions to figure out how to get to back to that menu instead of watching you tube videos forever which seem to kind of run in circles. I basically formatted a new a micro SD card in FAT 32 and dropped my .nds games along with everything for the r4i OMEGA folder. I tried opening the Labyrinth game in my 4.5 3DS and 9.0 XL and got that error message Cannot Open DS_menu.dat in both of them where before I got SD/TF error... I don't know if I was supposed to drop something in my SD card as well? Can anybody give me precise step by step instructions on what exactly to do to get my 3DS to run DS games or provide a link or else I'm probably going to mess up and accidently delete my 3DS backup game saves or something experimenting lol. Thanks ahead guys.
