Nintendo reportedly removes vulnerable app after Switch 2 jailbreak
Nintendo is reportedly taking SmileBASIC 4 off its eShop following the first public jailbreak shown for the Nintendo Switch 2. The tool had been used to exploit vulnerabilities in the new console, according to user reports and prior coverage.
What has disappeared from the eShop
The North American and European eShop listings for SmileBASIC 4 have reportedly vanished. The Japanese store initially still appeared to offer the software, but users are now saying it has been removed there as well.
Some reports suggest the app may still be reachable through alternative pages linked from the console News section, which could mean the removal has not yet been fully cleaned up across all storefronts.
How the exploit works
The jailbreak, referred to as ns2jb, abuses vulnerabilities in SmileBASIC 4, a programming application that originally launched on the first-generation Switch. It was demonstrated by running modified game content, including added characters in Mario Kart World, on firmware 23.0.1 without any hardware modification.
Early videos show what appears to be a Homebrew Launcher running on the Switch 2, marking an important step in the console early homebrew ecosystem.
Limitations of the current exploit
Despite the attention, the current method is still a userland exploit, not a full kernel exploit. It can execute native code with some system module permissions, but it does not provide direct kernel access or enable a permanent custom firmware solution.
Why the removal matters
Pulling SmileBASIC 4 from the eShop would stop new buyers from easily obtaining the app through standard purchasing channels. It would not automatically remove or disable copies already installed on devices.
Nintendo has not publicly confirmed why the app disappeared or disclosed a security patch for the exploit.
