Switch 2 Jailbreak: Nintendo Yanks Exploit App From eShop

By Indie Kings | October 25, 2026

Updated October 25, 2026: Nintendo has reportedly started removing SmileBASIC 4 from eShop regions after the release of a Switch 2 jailbreak that used it as an entry point, while the first homebrew footage continues to surface.

What changed on the eShop

VideoCardz reports that SmileBASIC 4, a Switch 2 programming application, has disappeared from North American and European eShops. The Japanese version was initially still available, but users now report it has also been removed. Some users claim they can still purchase the software through alternative pages accessible from the Switch 2 News section.

Why the exploit matters

The ns2jb exploit uses vulnerabilities in SmileBASIC 4. A security researcher used it to demonstrate a modified Mario Kart World with characters such as Peter Griffin and Hatsune Miku. The exploit works on Switch 2 firmware 23.0.1 and does not require hardware modifications. The first homebrew footage circulating on X already shows what appears to be a Homebrew Launcher running on Switch 2, per user AlexCVJ.

Limits of the jailbreak

Per VideoCardz, the current jailbreak is a userland level exploit, not a full kernel exploit. It allows native code execution with certain system module permissions, but it does not provide kernel access or permanent custom firmware. Removing SmileBASIC 4 blocks new purchases; installed copies are unaffected. Nintendo has not publicly confirmed the reason for the reported removal or announced a security patch.

FAQ

What did Nintendo remove?
SmileBASIC 4, reportedly from North American and European eShops, with Japan following per user reports.

Why does it matter?
SmileBASIC 4 was the entry point for the ns2jb Switch 2 jailbreak.

Do existing copies still work?
Yes, removing the app from the store does not disable copies already installed on consoles.

Is this a full jailbreak?
No, per VideoCardz, it is a userland exploit producing native code execution with specific system module permissions, no kernel access or permanent custom firmware.

Can it run homebrew?
First footage on X appears to show a Homebrew Launcher running on Switch 2.

Has Nintendo confirmed it?
Not publicly; no security patch has been announced.

Bottom Line

Nintendo is closing the gate from the store side while the exploit keeps spreading through installed copies. That is a strong move, but it does not solve the underlying vulnerability; the open question is whether Nintendo ships a firmware patch that makes ns2jb unusable.
