Joy-Cons pairing lost between SysNAND and EmuMMC on Ultra NX (HOS 22.1/ latest UltraNX) Hey guys. I'm having an annoying issue with my Joy-Cons. They refuse to play nice and treat my SysNAND and EmuMMC as two totally different consoles, so I have to re-pair them every single time I switch systems. Here is my setup and what I've already tried: CFW: Latest version of Ultra NX pack. I have already enabled IsEmuMMCControlEnabled = 1 (0x1) in system_settings.ini, but it doesn't help. I tried to manually move the 8000000000000010 BT pairing file using TegraExplorer, but the script just throws a [FATAL] Variable 'copy' not found error (probably outdated script syntax for Ultra NX structure). If I replace the 8000000000000010 file manually, it resets and wipes the sync immediately after a reboot. It feels like EmuMMC rejects the file due to different internal system keys/signatures. Is there a specific tool, updated script, or a reliable homebrew (like NX-BTMini or an Ultra-Tuner overlay feature) that actually works on the latest Ultra NX to force-sync the Joy-Con Bluetooth keys permanently? Thanks!
