Modder cracks Nintendo Switch 2 using legacy game code and AI assistance

Nintendo's much‑anticipated Switch 2 appears to have been compromised, as a hacker has demonstrated a working jailbreak that runs a custom version of Mario Kart World on the device.

The exploit hinges on code extracted from an older Nintendo title, which the modder fed into OpenAI's Codex, an AI system capable of generating software snippets. By leveraging the AI's output, the hacker was able to bypass the console's security layers and load unsigned code.

During the public demonstration, the modified game featured an eclectic roster of new racers, including Sanrio's Cinnamoroll, the red Angry Bird, the animated sitcom character Peter Griffin, and Minecraft's Steve. The inclusion of these characters highlighted the flexibility that a jailbroken system can provide for fan‑made content.

This development revives a longstanding tension between Nintendo and the home‑brew community. Earlier generations of the Switch were subject to similar hacks that unlocked the ability to run emulators and unofficial software, prompting Nintendo to issue firmware updates and, at times, pursue legal action against distributors of hacking tools.

Industry observers note that the involvement of AI tools like Codex could accelerate the discovery of vulnerabilities across a range of consumer electronics. By automating parts of the code‑writing process, such systems may lower the technical barrier for creating functional exploits.

As of now, Nintendo has not issued an official statement regarding the breach. Analysts expect the company to roll out a security patch in upcoming firmware updates, while also monitoring the situation for potential copyright or trademark infringements stemming from the unauthorized use of third‑party characters.
