A reported jailbreak for the Nintendo Switch 2 has surfaced, with a user claiming to have used a SmileBASIC-based exploit to run homebrew and game mods on the new console.
According to online reports, the discovery comes a little over a year after the Switch 2's launch and was posted publicly by a user operating under the handle "pepsipu." The claim has drawn attention because it references both SmileBASIC and AI tools in the development process, and because it targets Nintendo's current hardware.
The reported exploit, as described by the discoverer, involves SmileBASIC version 4.4.9 and requires access to a Switch (referred to as Switch 1 in the report), a PC, and the Switch 2 console.
The process is described as involved and must reportedly be repeated each time a user wants to enable the hack.
Per the report, the technique allows the injection of homebrew, game mods, and save-file backup operations on the Switch 2.
In a Twitter post dated October 22, 2026, the user "pepsipu" wrote that they had jailbroken a Switch 2 and used the exploit to mod Mario Kart World, claiming to add characters such as Cinnamoroll, Peter Griffin, and Hatsune Miku to the game.
Paraphrasing the post in journalistic terms: the user stated they successfully modified a Switch 2-exclusive copy of Mario Kart World to include non-standard characters, posted demonstration footage, and shared a link they said led to the exploit.
SmileBASIC is a BASIC-based programming and development environment historically associated with SmileBoom, and it has been available on Nintendo platforms in prior generations.
Multiple outlets and user reports indicate that SmileBASIC was removed from the Nintendo eShop following these disclosures; those accounts attribute the removal to Nintendo or to eShop storefront changes.
These removals and the original exploit report are being circulated in developer and modding communities.
Security commentary within the community notes that exploits operating at the software level are often mitigable through firmware updates and storefront changes; however, no official statement from Nintendo addressing this specific report has been published at the time of these reports.
The original discoverer also claimed assistance from AI tools in crafting the exploit, a detail they included in public posts.
This story remains driven by first-party posts from the discoverer and subsequent reporting on storefront availability.
Readers interested in broader context on Switch platform security, homebrew development, and Nintendo's historical responses to exploits should follow official Nintendo communications and established technical analysis from recognized security researchers for confirmation and guidance.
