A modder has jailbroken the Nintendo Switch 2 using an old game and OpenAI’s Codex, showcasing a custom Mario Kart World with new playable characters.
A modder has announced the first jailbreak for Nintendo’s newly released Switch 2, demonstrating the console running a custom‑built version of *Mario Kart World* that adds characters such as Cinnamoroll, the red Angry Bird, Peter Griffin and Steve from *Minecraft*. The exploit, dubbed “ns2jb”, was assembled with the assistance of OpenAI’s Codex, which generated portions of the code needed to bypass the system’s security checks.
The breakthrough matters for several reasons. First, it proves that the Switch 2’s protection mechanisms can be subverted, raising concerns for Nintendo about potential piracy, unauthorized software distribution and loss of control over its ecosystem. Second, the involvement of an AI coding model underscores a growing trend: generative tools are increasingly being repurposed for security research and, in some cases, malicious activity. As we reported on 21 October, OpenAI’s models have already been used to uncover significant software vulnerabilities, and this jailbreak adds a concrete example of AI‑driven exploitation in the consumer‑hardware space.
What to watch next includes Nintendo’s official response—whether the company will issue a firmware update, pursue legal action against the modder, or adjust its security roadmap. The home‑brew community is likely to test the limits of the new jailbreak, potentially expanding the range of custom games and features. Meanwhile, security researchers will monitor whether other AI tools, such as newer versions of Codex or competing models, are being leveraged for similar console hacks, which could prompt broader industry discussions about responsible AI use and device protection.
