First flash card to work on Any 3ds and firmware! This card is for if you just want to play the game. if you're looking for home brew, ar code support, and custom crap get a gateway 3ds flash card
(the cheapest legit place to get this card is modchipdirect)
this DS card is the best thing for playing DS games on your 3ds! its also capable of playing gba games and snes games too! this is also the only game card to have a 400mhz cpu and extra ram to help increase speed for faster emulation.
Much like the acekard 2i it can also do homebrew and many customization's.
For best response time use a class 10 micro sdhc card.
