I have a hacked o3ds in bad condition and want to transfer to another 3ds. The current 3ds doesn't use a9lh, only emunand booted by menuhax. I'm going to buy a new one and put a9lh on it. I want to keep all my cia and cart save files of course. How do I do this? Also are all firmwares hackable or do I need to buy a specific version?
