Nintendo has released Switch 2 system update 23.5.0. Mod author and data miner OatmealDome stated that this version patches an OS vulnerability exploited by recent jailbreak methods, thereby restricting the ability to dump games and apply mod modifications once again.
The previous method used SmileBASIC 4, a programming application available on the eShop, as an entry point. It was a tethered jailbreak requiring the software to remain running. If the device is powered off, users must repeat the process. Despite this limitation, users were able to dump Switch 2 games and assets, and modify titles such as Mario Kart World.
Reports indicate that within hours of The Legend of Zelda: Ocarina of Time Remastered's release, its Switch 2 version was dumped and run on PC. OatmealDome stated that after installing 23.5.0, it is no longer possible to "escape" from the game environment; homebrew programs can only operate within the limits allowed by the game itself, making game dumping and modification unfeasible again.
However, OatmealDome believes that some recently released physical cartridges and certain updates may remain unaffected. SwitchTools judges that new physical games can still be dumped and game key cards are unaffected, but additional restrictions apply to handling digital games, updates, and DLCs.
These assessments come from third-party technical experts, and the actual scope of the patch remains to be further verified. Some users have stated they will refuse to install this update to preserve vulnerabilities in older system versions.
