Hi, I have an original Heart Gold cart that refuses to start. I get the following message: "The save data could not be accessed." "Please turn the power off and reinsert the Game Card." I have tried it in 3 different DS consoles with the same result. I have cleaned the contacts to no avail. I have then removed and inspected the PCB which looks squeaky clean with no signs of wear or damage. Do you think this can be fixed with something like an NDS Backup Adapter Plus? I have tried to find out if Junior did anything to it and he just starts sobbing so who knows!!
