## First public jailbreak for Switch 2
A modder published the first public jailbreak for Nintendo's Switch 2 using OpenAI's Codex.
## Software-only exploit ns2jb
The software-only exploit ns2jb works on firmware 23.0.1 and requires a separate computer to run.
## Demonstrated capabilities
It enables homebrew programs, save file backups, and modified Mario Kart World with unlicensed characters.
## Tethered nature of exploit
The jailbreak must be re-run after every reboot and requires a separate computer running Linux or macOS.
## SmileBASIC 4 pulled from eShop
SmileBASIC 4 has been pulled from the Nintendo eShop in the US and Europe, leaving only existing users.
## AI-assisted development process
The researcher used OpenAI's Codex with a JetKVM and SwitchBot to control the console's input and output.
## Two weaknesses exploited
Codex first attacked WebKit and SmileBASIC 4's numeric routines before finding a file system vulnerability.
## Mario Kart World mod
The modder created a Mario Kart World version with unlicensed characters like Cinnamoroll and Peter Griffin in a day.
## Validation and timeline
The exploit was validated on October 21, 2026, succeeding on the third attempt after a reboot.
## Key takeaway

A modder cracked Nintendo's Switch 2 using OpenAI's Codex, allowing homebrew apps and unlicensed game mods.
