It's the one from r4igold.cc. I know it works because I've used it on my 3DS (b9s'ed) several times. I left my 3DS to my sister before moving because she uses it more, lmao. So now I've ordered a used DS Lite and ironically, it is not recognized on this unit! It says "There is no Game Card inserted." on the main menu. I already tried the paper trick (even slid cardboard between the cart and the slot) wrapped tape around it and it still won't work. I honestly need all the help I can get, please.
