You have to ask questions in specific thread - https://gbatemp.net/threads/switch-noob-paradise-ask-questions-here.488277/page-2139wow thanks i Love you
How to use it?
Otherwise, most members won't bother to type a lengthy instruction due to time constraint and if they did, some continue to not understand to make more complicated.
I'm only able to help is find saves and fix the problems with saves, but I have no control if there is problem with tinfoil and if I know a public invitation to Discord, I would able to give a proper instruction.
Important Note: As for save sharing - you must use JKSV (JK's Save Manager) to export/import the saves. You must have hacked Switch. You must have access to computer that allow file manager to put saves in SD card. Checkpoint may works in old firmware but can't speak with newer firmware. JKSV is most preferred tool, also ACNH requires JKSV due to device save. You must run JKSV at full RAM (hold R while open the game), otherwise, JKSV can crash randomly.
Don't waste your time to ask if your Switch is hacked, patched, etc in here, so you have go to specific thread that I gave above for proper help.
