Switch 2 gets its first software jailbreak: ns2jb
Researcher pepsipu (Sammy Hajhamid) showed ns2jb. It runs custom code on Switch 2 firmware 23.0.1. The demo added new characters to Mario Kart World. It uses bugs in the SmileBASIC 4 app and in the system's file module (fs). It is research / proof of concept: it doesn't work on the console alone, is gone after reboot and has no kernel access.
