There are only 2 tools (to my knowledge)Thanks. That was some useful knowledge. Can you tell me what the most popular tool is right now for manipulating NSP/XCI files? Everything I find was created in 2018 so not sure if they're discontinued projects or just have no need for updates anymore. I was looking at Switch Backup Manager for instance. I have an XCI file that contains the base game and the update. I wanted to split them into separate NSP files.
