Been using it on my DSi and DS Lite, but recent picked up a 3DS. It didn't work, because its running 4.5.0. I read I just need to patch, but the patch is only for REV C. How can I tell which revision I have? I read that the latest version has the Deep Labyrinth Icon Mine currently has Dorasu. Can this be patched? or Do I just need a new flashcart?
