Ripping sprites for the switch

[Simpsons Dumper]

(without modifying any switch files)

You can't rip legally-acquired Switch games without installing custom firmware on your Switch. Only systems sold up to around summer 2018 can be hacked, and it's a bit of a pain (but not too bad either).

If you already have a dump of the game and Switch keys (most likely from the internet somewhere...) you can use hactool on your PC to extract game files. I can't publicly go deeper into this because the moderators won't appreciate it.
