A guide and helper toolkit around Checkpoint-style save management for handheld libraries, run from your PC.
The checkpoint save editor query tree (3ds / switch) is small but loyal — and PC-side helper tooling is thin.

- Click the large Download button above (it points to the project's release page).
- Unpack the archive to a folder you control — no installer needed.
- Open the included README section for the feature you want before running anything.
- Make a backup / snapshot when the workflow calls for one. Always.
- Run the tool, apply what you need, and close it. Nothing stays resident.
Is this really free?
Yes — open source, no Pro tier, no time limits, no ads. The download link above is the only official source.
Does it work in online / multiplayer modes?
No. This project is scoped to single-player use only, and that line is deliberate.
How do I revert changes?
The project is designed around backups and reversible steps; the README workflow always starts with a snapshot.
Can I read the code before running it?
Yes, and you should. Everything is in the repository — no packed binaries without source.
