Ok I have gotten my replacement Acekard2i from RHS, and I am using a DSi. I have put the AKAIO 1.6 on it. Now when I try to play Tetris DS online, sometimes when waiting to connect to someone else, it says the game card has been removed, please re-insert the game card. Sometimes it lets me play and then it says you cannot play with this Friend Code and then it freezes. Anyone else have this problem?
