Nintendo has introduced another restriction targeting the first known Nintendo Switch 2 jailbreak, making it more difficult for users to exploit the console through SmileBASIC and Civilization VII. According to Switch 2 hacker OatmealDome, both games now require the latest system firmware before they can be launched on consoles connected to the internet.
The change means that Switch 2 owners who have not updated their systems will lose access to these games once the update requirement is triggered. Both titles previously served as entry points for the software-based jailbreak discovered in late October 2026.
OatmealDome explained that once the system update prompt appears, users can no longer access the jailbreak through either game without updating their console.
At that point, users must either install the latest firmware or find another game that can serve as an entry point for the exploit.
The restriction follows Nintendo’s release of Switch 2 firmware version 23.5.0 on November 9, which patched the operating system vulnerability that made the jailbreak possible.
According to OatmealDome, the update effectively prevents users from dumping and modifying games through the previously available method, although certain cartridge games and potentially some game updates released in the near future may remain exceptions.
The underlying game-level exploits in SmileBASIC and Civilization VII have not been eliminated. However, firmware 23.5.0 prevents those exploits from escaping the games’ restricted environments, commonly known as sandboxes.
As a result, homebrew software can only operate within the limited capabilities already available to those games, significantly reducing what developers can accomplish.
The Nintendo Switch 2 jailbreak first appeared publicly in late October 2026, becoming the console’s first demonstrated software-only exploit.
Modders subsequently used the vulnerability to dump game ROMs and introduce custom modifications into Switch 2 exclusives, including Mario Kart World. Developers involved in the scene also highlighted the growing use of artificial intelligence tools to help identify console security vulnerabilities.
Nintendo Switch 2 originally launched worldwide on June 5, 2025, for $449.99. Its retail price increased to $499.99 in September 2026, and the console surpassed 23 million units sold during its first year on the market.
