I read the setup guide and searched around. I could get any problems to fix mine. This is what I did. I opened my Acekard2i I download AKAIO 1.8.5, Unzipped it. I formatted the Micro SD card with the SD formatter. I moved the _aio and akmenu.nds to the root of the sd I put ak2loader.nds in the loader folder I put Sonic Colors.nds onto the root of the SD I ejected the SD I pushed the card into the spring loaded Acekard2i until it clicked I insterted it into the Brand New DSi which was always at version 1.4.1U I selected the card on the menu which showed Alex Stormrider. A blue "Loading" appeared. Thats where I am stuck I tried a different SD card one that is 4gb but it has the same problem. I suspect it is the Acekard but i wanna get some opinon be for I return it maybe it is something i did wrong. I bought it from Shoptemp. So yea . . . any tips??
