I purchased a AK2i from 4coolday.com it was one the AK4i that came in a cardboard box with the orange sticker. I popped it in and it does not even see that there is a cart placed in the dsi. I am using a Micro SD 4 gig HC. I tried using official firmware and AKAOI the dsi will not show anything. I am using the latest loaders,the ones after April 19 2009. I tried making the cart thicker to see if it was a contact issue, but still nothing. My question with or without an SD card in the cart it should be able to recognize that something is in the dsi. If anyone has any ideas I am all ears, thanks .
