So, I've found my old ds flashcart (acekard 2) and I'd want to use it on my 3ds. However I'm unable to get into the flashcart's menu. I know that there is already a method for that but I can't find it. I have cfw, I'm just looking for a .cia app that enables the old ds flashcarts. Thank you for taking your time to read this post, Have a nice day.
