My Acekard 2i works in a regular ds but in my DSi won't read it unless I keep it held down a little further in. I'm thinking maybe I could use some glue or something to help it stay down far enough. Just to make sure everyone knows this my Acekard 2i DOES work and has the firmware update needed for (1.4). The only issue is that it doesn't get proper contact for my DSi to read my card. Any ideas or help you can give me is greatly appreciated.
