Using sys-tweak to bypass linked Nintendo account requirements
I have no idea why this functionality was never documented, but one thing sys-tweak can do, is bypass games' requirements for a linked Nintendo account, without having to link a real or fake Nintendo account.
This is useful because 1: why link an account if you don't need one? and 2: Nintendo behavior throws a shit ton of erpt errors if you're connected to the internet while having a linked Nintendo account that can't actually connect to the servers (whether you're banned, or it's a fake/invalid account, or you're purposefully preventing connections by blanking prodinfo or blocking Nintendo with dns.)
How to do this:
1. Build sys-tweak with FEAT_NSAM_CONTROL and FEAT_NSRO_CONTROL at minimum (p-sam/switch-sys-tweak on GitHub), or download one of the pre-built files others have been sharing online
2. Rename to exefs.nsp and place on your SD card in /atmosphere/contents/00FF747765616BFF (create the folder manually)
3. Create a "flags" folder alongside it, and in that folder, create a new empty file, which you will rename to boot2.flag (creating a new empty .txt file is one way to do this.)
Now sys-tweak is set up and should automatically run at boot. From there, for every game or application that asks for a linked Nintendo account:
1. Find the title ID for your game or application, and create a folder of that title ID under /atmosphere/contents/
2. In that folder, create a text file, rename to config.ini, and paste the following in it:
Save that file, fully reboot your console to make sure the new files are being read and taken into account properly, and your game should work without a linked account.
Note: I cannot guarantee that this will work for everything. Most single-player games that ask for a linked account despite there not being a reason to require one will probably work fine, but some other games or applications need the Nintendo account and will crash if you force it to run without one. Feel free to try this with various games and reply with what worked and what didn't, so others can know if this would work for them. The only one I've tested is Bloodstained: Ritual of the Night.
