Hello, I'm not sure what the problem is. I have an Acekard 2i and it will not read on my friend's nintendo dsi (firmware 1.3u). It works perfectly on my nintendo ds lite and even on my nintendo 3DS. But when I put the cart into the dsi, it will not even read. It says no cart is inserted. The dsi works perfectly with real cartridges. I don't think it is a contact issue either. Should I update the dsi? Will that work? I'm using an acekard 2i with all the latest updates (i'm pretty sure, got it from acekard's front page) and I even use the panasonic formatter on the microsd. Any help would be appreciated, thanks!
