## Summary

Modder Sammy Hajhamid, known as “pepsipu,” demonstrated a software‑only jailbreak for the Nintendo Switch 2 that he says was built with help from OpenAI’s Codex. The exploit, dubbed “ns2jb,” runs a custom version of Mario Kart World that includes characters such as Cinnamoroll, the red Angry Bird, Peter Griffin and Steve from Minecraft. Hajhamid’s claim about Codex’s role comes directly from him, and no official comment has been provided by Nintendo or OpenAI.

The jailbreak is tethered, meaning it must be launched from a game each time the console powers on. It relies on the title SmileBASIC 4, a programming game, although another modder has suggested the game may not be strictly required. The technique appears complex for most users, and the broader impact remains unclear; discussions on the Switch 2 hacks subreddit are debating how significant the exploit is. If AI‑assisted tools continue to aid modders, the Switch 2 could see a series of similar exploits in the near future.

## Key points

- Modder pepsipu used OpenAI Codex to develop the ns2jb jailbreak for Switch 2.
- Jailbreak is software‑only and tethered, requiring the game SmileBASIC 4 each boot.
- Custom Mario Kart World demo adds characters like Peter Griffin and Steve from Minecraft.

## Why it matters

The use of AI code tools to break a new console highlights emerging security risks and could accelerate future hardware exploits.
