Do Switch cartridges save on cart or system?Well, telling from the photos, It could be the saves saved onto cartridge, and digital into System Memory, because like a 3DS, saves are on carts. Not entirely sure because I have 1 Switch console, not 2. Anyway it could be exciting to see BOTW and MK8D and Splatoon 2 save editors. I think personally the first homebrew should be the launcher and then save managers like JKSV, I wouldn't care if the save manager was in text mode or not.
On the Wii U it was in system, but maybe because those were disks, I'm not sure about Switch games.
