Nintendo Switch 2 cracked: First jailbreak opens the door to mods
A first partial jailbreak for the Nintendo Switch 2 has appeared. Through the use of AI, it has been possible to partially bypass the security systems. This enables the first mods in games and could soon lead to further exploits.
First hack for the Switch 2
A first partial jailbreak for the Nintendo Switch 2 has appeared. A little more than a year after the console’s market launch and the discovery of the very first exploit in 2025, system restrictions should be able to be circumvented without a hardware modchip. This potentially opens the door to the modding, emulation and homebrew communities. A video demonstrates the exploit using the racing game Mario Kart World. The developer has integrated running versions of characters such as Peter Griffin, Hatsune Miku, Cinnamoroll and Red from Angry Birds into the title. The software hack called ns2jb is intended to grant access to the file system and allow native code to be executed on consoles with firmware 23.0.1.
i jailbroke the nintendo switch 2 so i modded cinnamoroll, peter griffin, hatsune miku, and more into Mario Kart World, a switch 2 exclusive now watch my friends and i get cooked by bots learn more and get the exploit https://t.co/ykjgyfrFRp https://t.co/BOcFhejRz1— pepsipu (@pepsipu) October 22, 2026
As pepsipu on X reported, the jailbreak was created using the AI model OpenAI Codex. The language model is said to have analyzed the code for vulnerabilities. A setup was used that sent controller inputs to the console and, in the event of crashes, triggered a restart via a Bluetooth switch. According to the report, a first attempt using the WebKit browser engine only provided limited rights.
Vulnerability in old game
The Switch game SmileBASIC, which runs on backwards compatibility, ultimately served as a gateway. The AI is said to have found an error there that was based on an integer overflow. A buffer overflow could be used to redirect cached data. The system is said to have allowed access to protected files and circumvented security checks. However, the jailbreak still has technical limitations. It is a so-called tethered solution. This means that the hack will not survive a console restart and will have to be re-run afterwards. In addition, complete access to the kernel level should not yet be possible. Custom firmware or pirated copies cannot be run using this method.
Rapid development thanks to AI
Nintendo has always taken tough action against software piracy. Since the game required for the exploit is known, the Japanese company is likely to remove it from the eShop promptly and close the gap. However, exploits, ports and mods for consoles have been on the rise recently. Thanks to current AI models, a number of PlayStation games now run on the Xbox and the PC and vice versa. The current partial jailbreak of the Switch 2 could lead to a similar flood of hacks and ports on the Nintendo console. With the previous model, users were able to run PC games like Final Fantasy VII Remake on the hardware.
