Hi, I bought an Acekard 2i from someone secondhand, and both my old and new 3ds cannot recognize it. The metal "connector" part is quite dirty, so I suspected that this flashcart has simply died of old age, but the seller claimed that the problem lies with the flashcart's "ROM". I assume he meant that the cart's old firmware is in the blacklist of the 3DS, but both of my 3DSes has CFW and should be immune to the flashcart blacklist problem. Can anyone shed some light on what is really going on? Is the seller lying?
