Checkpoint 4 modernizes save management on Nintendo 3DS and Switch

Bernardo Giordano pushed Checkpoint 4.0.0 to GitHub with the kind of changes that make save management feel less like a chore and more like a safety net. The project called it the largest Checkpoint update since its original release 9 years ago, and the overhaul is aimed squarely at players who move saves between original hardware, modded systems and PC backups.

On Nintendo 3DS, the headline additions are support for backup and restore of GBA Virtual Console saves and DSiWare saves. That fills real gaps for anyone trying to preserve a long playthrough before tinkering with homebrew, swapping SD cards or migrating a handheld collection to a different setup. Checkpoint already handled 3DS and DS cartridges, digital standard titles and demo titles natively, but version 4 pushes deeper into the libraries where progress can be easiest to strand.

The practical side of the update is even broader. Checkpoint 4.0.0 added a background FTP server so users can reach save backups from a PC directly through the app, plus a new in-console Settings section for editing config.json without opening the file by hand. It also brought light and dark themes, a folder browser for picking additional save folders on-device, a quick-backup toggle that skips the name prompt, a confirm-restore toggle, support for additional save folders for DS titles, multilingual support in English, Italian, French, German, Portuguese, Spanish, Dutch, Japanese and Chinese, and a way to cancel a backup by holding B.

Under the hood, the update is built to cut friction. File handling now uses async I/O in a worker thread instead of tying up the main UI thread, while cached and uncached title loading and cached text storage were tuned for faster rendering. For players juggling a console, a PC and a habit of keeping multiple copies of the same RPG save, that means less waiting and fewer chances to interrupt the process at the wrong moment. On Switch, Checkpoint still focuses on NAND saves for titles the user has played, but the update’s new graphics system and sharper docked output make the tool feel more polished where people actually use it.

One notable change is the removal of the cheats feature, which the project said was no longer sustainable to maintain because of the cheat database. That decision leaves Checkpoint leaner, but the release still reads like a major reset for one of homebrew’s most practical utilities. For a tool that exists to protect progress, the new version is built around the same idea from the first screen to the last saved file: make the backup obvious, make the restore safer, and make the path between console and computer as short as possible.
