mac2jb v0.8.0 expands CivSwitch tools with an experimental ns2jb-modloader port
mac2jb v0.8.0 adds a CivSwitch filesystem jailbreak path and an experimental ns2jb-modloader port, according to the project’s November 11, 2026 release notes. For readers following Switch 2 modding, the experimental label is a key qualification: the notes describe a port within this toolchain, rather than establishing broad compatibility or reliability.
CivSwitch gains more launch options
The release describes a CivSwitch filesystem path that opens a held session for SaveKit, OunceCake and the experimental modloader port after what the project calls “4/4 verification.” The supplied notes do not explain that verification process or specify supported firmware versions.
For a verified CivSwitch loader, mac2jb also adds CivHomebrew and Moonlight options. Those additions come with a guided first-time transfer and saved boot trigger controls, bringing setup and launch controls into the release’s list of changes.
A separate Seedsow Lullaby filesystem path is also marked experimental. Its stated prerequisite is an Artemis HTTP launcher that is already running.
Save handling and bundled tools change
Beyond the launch paths, SaveKit gains support for larger save writes and verification after writing. The update also bundles Balatro RCE v1.1.0 and GravCirc save installers with verified backups, and adds WebDAV and FTP choices for OunceCake.
The bundled Artemis launcher saves move to v2 for Seedsow Lullaby, Nora Princess 2 and Hamidashi Creative. Other additions include the Nora, Princess and Stray Cat HD demo, a Seedsow full-game installer, Seedsow Lua Editor Pro v0.4.0 and NXFormat in the developer tools.
The release therefore spans both experimental launch work and changes to the accompanying save-management tools. Its notes leave the experimental paths’ wider compatibility unresolved.
