So I'm in the same, exact situation as OP. My goal is to have game backups, like game card dumps, and play Smash Ultimate online. (I'm a tournament go-er. Online is a MUST.) Sounds like if I even want to get anywhere close to having a hacked Switch, but remain undetected; I'll need a secnd Switch? What about dongles like SX OS and the new R4 that was dropped? Don't that have any bearing on keeping the Switch anonymous to Nintendo? Are they achieving anything further than what's current for CFWs?
