I gave my younger nephew an up-to-date flashcart for his upcoming 3DS. As siblings are prone to do, now his elder brother is moaning he wants a flashcart too for his DSi, despite the fact he rarely games and as a consequence is not so great at it. I've got an Acekard, an Ace3DS Plus and an R4i 3DS Gold to hand. How do I go about finding which are compatible and updating them as necessary?
It's for 3DS, but the ones working on the 4.5.0-10 will work on the DSi 1.4.5. http://pongupdates.wordpress.com/flashcards-working-on-3ds/
