So, I recently got an acekard from a friends which was working great, and it was functioning properly. But, my sister tried to update my DSi's system, and then the Acekard stopped working. When I put the cartridge in, it still shows "Danny Phantom", but once I click on it, it says there is an error. I have tried inserting paper, but to no avail. I also tried to update the cartridge for 1.4 using an old DS Lite, but although the update is fine, it has no effect on what happens on the DSi. I have also tried to reset the DSi, but that also did nothing. Could someone help me figure out what I need to do?
