are those NDS roms i see on sites for you to download for emulators or can you actually put those games on your DS, because i know DS take catridges but im just curious because you do have a link cable on the DS.
Those DS files can be put on your DS, using certain Hardware, like the M3, and Passcard 3. This lets you run emulators, homebrew, and backups on your NDS.
On the NDS roms when it has a J, U, E at end of roms does this mean its the Japan version, USA version and Europe version. Thank you in advance.
