So thank you to everyone who helped me set up my New 2DS! But there has been one problem I haven't been able to solve and that is transferring the save data of ACNL. I tried using checkpoint but it just told me my save data was corrupted and needed to be deleted. Then I had given up and just put the cartridge in the console. I gave up on trying to transfer save data to the CIA and just thought I'll play the cartridge when it also said to me my save data was corrupted and needed to be erased. Mind you I can easily load it up on my O3DS with no problems. What am I doing wrong guys? Thank you to everyone I always appreciate your help!
