So i followed Mr. Hanky's guide and when i put my cartridge in my ds lite i get "couldn't find_DS_MENU.DAT" I have everything I need to work the m3, but it doesn't want to work. I downloaded the firmware, I downloaded some roms, and then I downloaded winrar. Whne I extract them I extracted to my microSD card (I don't know if that is to the root of the microSD card or not) and then I extracted the roms as well to the microSD card and when I go to play them in my DS I get the message i mentioned before. If anyone can help me I would be greatly appreciated. Thanks!
