AI overview

Researcher pepsipu demonstrated a Switch 2 jailbreak running a custom version of Mario Kart World, leveraging OpenAI Codex and the legacy game SmileBASIC 4. The software-level exploit requires binding to SmileBASIC 4 and must be re-executed every boot; it remains an experimental breakthrough with no broader implications beyond this specific customization.

    Report first recorded Oct 23, 02:10

    The Nintendo Switch 2 has been jailbroken, allowing a modder to run a custom version of Mario Kart World featuring new characters like Cinnamoroll, the red Angry Bird, Peter Griffin, and Steve from Minecraft. This software-only, tethered jailbreak, created with help from OpenAI’s Codex, requires running from a game like SmileBASIC 4 every time the console is turned on, and its full impact is still under debate by users on the Switch 2 hacks subreddit.
