Nintendo Switch 2 Homebrew Launcher reportedly appears as SmileBASIC 4 vanishes from eShop listings
Nintendo Switch 2 homebrew activity appears to be moving quickly after the public disclosure of a new software-only jailbreak. Fresh footage circulating online seems to show a Homebrew Launcher running on Nintendo’s latest console, while SmileBASIC 4, the app used to trigger the exploit, has reportedly become unavailable on several regional Nintendo eShop storefronts.
The exploit, called ns2jb, was developed by security researcher Sammy Hajhamid, also known online as pepsipu. According to the researcher’s technical breakdown, ns2jb can enable native code execution on Nintendo Switch 2 firmware version 23.0.1 without requiring hardware modifications.
However, this is not a full custom firmware solution. The jailbreak is limited, must be triggered again after every reboot, and does not currently provide persistent access or kernel-level control.
Videos appear to show Homebrew Launcher running on Switch 2
Shortly after ns2jb became public, videos began appearing online that seem to show a Homebrew Launcher operating on the Nintendo Switch 2. Another clip reportedly shows HBLauncher v1.0.0 running on the console, suggesting that developers and enthusiasts are already experimenting with the exploit.
A separate demonstration also claims to show Vulkan graphics support working on the Switch 2. Vulkan is a low-level graphics API often used in games and performance-heavy applications, so even partial support could be significant for future homebrew development.
That said, these videos should be viewed with caution. While they suggest promising progress, they do not prove that a complete, stable, and widely usable Nintendo Switch 2 homebrew environment is available to the public.
SmileBASIC 4 reportedly removed from multiple eShop regions
At the same time, SmileBASIC 4 has reportedly disappeared from Nintendo eShop listings in several regions, including North America, Europe, and Japan. The timing has drawn attention because the ns2jb exploit relies on vulnerabilities connected to SmileBASIC 4 when the app is used through the Switch 2’s backwards compatibility system.
SmileBASIC 4 is a programming application originally released for the first Nintendo Switch. Because the exploit depends on this app, its disappearance from storefronts could make it harder for new users to reproduce the jailbreak if they did not already purchase or download a compatible version.
Still, availability reports have been inconsistent. Some users claim the app can still be reached through alternative eShop entry points, including pages opened from the console’s News section. If SmileBASIC 4 has been removed from sale in certain regions, that would not automatically erase copies already installed on users’ systems.
Nintendo has not publicly stated why SmileBASIC 4 is missing from some listings, and it remains unclear whether the change was made because of the exploit.
How the ns2jb exploit works
The ns2jb jailbreak combines vulnerabilities involving SmileBASIC 4 and the Nintendo Switch 2’s filesystem services. By chaining these issues together, the exploit can run native code with elevated system-module privileges.
To demonstrate the exploit, Hajhamid showed Mario Kart World modified with unofficial characters, including Hatsune Miku, Peter Griffin, and Cinnamoroll. The demonstration helped show that the exploit can affect real software behavior, not just launch a basic proof of concept.
Even so, ns2jb remains limited in important ways. It is a tethered exploit, meaning it must be relaunched after the console restarts. It does not install permanent custom firmware, and it does not provide full system access. Public documentation also lists specific software and network requirements needed to reproduce the setup.
What this means for Nintendo Switch 2 homebrew
The reported Homebrew Launcher and Vulkan demonstrations show that the Nintendo Switch 2 homebrew scene is already experimenting with the new jailbreak. For developers, the ability to execute native code without hardware modifications is an important early milestone.
However, the current situation is still far from a mature homebrew ecosystem. The exploit depends on a specific application, appears to be affected by regional app availability, and still lacks the deeper access usually needed for long-term custom firmware development.
For now, the story around the Nintendo Switch 2 jailbreak has two major angles: early homebrew progress and uncertainty over access to SmileBASIC 4. Whether ns2jb becomes the foundation for broader Switch 2 homebrew development will depend on how developers expand the exploit and how Nintendo responds in future firmware updates.
