I ordered my Acekard 2.1 from DX and received it almost a month later. I'm using a genuine Kingston 8GB Micro SD which has been formatted to FAT32. I have downloaded the official firmware [Version 4.18. Fixed 3966 and 3665.] from the Acekard website. I have also tried the AKAIO firmware, and older official Acekard firmware. I have unzipped the file into the Micro SD. My DS Lite loads genuine cartridges fine. Whe I put the Acekard 2.1 into the DS and turn it on I get the following: On the touch screen where you select the DS cart to load I get the screen you would normally get with the little icon to the left in the little square and the cartridge info to the right in the rectangle. However both these are blank. When I select this "cartridge" the DS makes a noise acknowledging I have made an input on the touch screen and then displays two blank white screens, they remain no matter how long I leave the DS on. I get the same result whether my Micro SD is in or not. I have tried a little spacer behind my Micro SD in case it wasn't making contact with the pins in the Acekard, this did not help. My Micro SD works find with my PC. Is there something obvious I have not done, or is my Acekard 2.1 D.O.A. ? Thanks.
