My friend recently ordered an Acekard 2i and he's having issues with it. When he got it out of the box, I made sure the first thing to be done was get the AKAIO firmware. So right now, the Micro SD on the system has the __aio folder and akmenu4.nds on it, and nothing more (Firmware AKAIO 1.5.1). However, the issue seems to not come in with the SD, but the cart itself. He tried the 2i on his DSi (unsure of the firmware), and it didn't detect the cartridge--it acted as if nothing was in the system. He then attempted to try it on his DSLite, and again, it acted as if nothing was inserted. He had another friend who tried his 2i on both of the systems, and his 2i cart read just fine on both... I'm not really sure what to do about this, perhaps somebody could shine some light on the matter?
