anybody can confirm that this works?
this works the same with calling nintendo support to remove your account from current system right?
also the page states
"Your Nintendo Switch will no longer be registered as the primary console for your Nintendo Account."
so that means it won't deregister 3ds and wii u from your account, only the switch right?
Here's how it works since 6.0.0
ScenarioA:
If you have Console A with registered account as primary, you can setup your account on another Console B and download all your purchases again without deregistering. The only caveat is that you have to be logged in online to play any of that content (technically you can share your collection and you can both play at the same time as long as ConsoleA is offline while ConsoleB is connected online, since ConsoleA doesn't need internet access to play the content because it's the primary console).
ScenarioB:
You diregister ConsoleA as primary and set the ConsoleB as primary... then the same as Scenario A happens except you substitute ConsoleA and B in the example above.
Back on topic: Now here's my experience so far.
I have my primary console with NNID where I have purchases and play my legit games online. I've booted into RCM a few times so far, the first time was to back up my NAND, then i booted again into RCM to backup my saves with checkpoint. The first time I tried it, it crashed, restarted console, retried and it worked, afterwards I restarted and played normally my games, no bans. Last week I did the same thing again restarted into RCM amd backed up my saves with checkpoint and now I'm still able to boot into my system, access eshop and play online.
For my second console, I never setup my NNID on it, first thing I did was a NAND backup, then I started running xcis and nsps through sx-os. It has been connected to Wifi and able to update all my games through wifi, no bans so far either. I never hacked saves or anything like that but I did restore some saves from ConsoleA to ConsoleB.
For my ConsoleA and B, everything mentioned above has been done on 5.1.0, but now both consoles are on 6.0.0 and no issues so far.
So not sure if any telemetry report gets sent if you don't have an NNID otherwise i don't know how I'm not banned yet. I'm waiting for Emunand on mSD to use my console the same as my second Obviously if eventually I do want to take this second console online, I would do a NAND restore before hand as I'm sure my report is full of flags at this point.
Make of that what you will, but everything above is true.
Pro tip: for anyone with hacked console offline. Sometimes I have friends that come over with their switch and they've never connected online and we want to play a game through local multiplayer. But our game versions don't match, what we do to ensure we all have the same version is use the offline patch sharing feature, it works wonders and no need to be connected to WiFi, its awesome as we don't have to mess with NSP or RCM or anything else.
