Someone hacked the Switch 2 by using an old game and AI

A modder known as "pepsipu" (Sammy Hajhamid) has apparently jailbroken the Nintendo Switch 2, demonstrating the console running a custom version of Mario Kart World with added playable characters including Cinnamoroll, the red Angry Bird, Peter Griffin and Steve from Minecraft. According to Hajhamid, OpenAI's Codex helped create the jailbreak, published as "ns2jb" on GitLab. The work matters because it is an early claimed break of the Switch 2's protections, achieved with an older game and an AI coding tool.
