Notes from the Checkpoint64 team.

📌 Pinned
Counter-Strike has no save file; it still has four hours of your settings. Checkpoint64 now backs up game and server configs
A competitive shooter keeps your progress on the publisher's servers, so there is no save to back up. What sits on your disk is the config, and that is the part you rebuild by hand after a reinstall. Checkpoint64 now stocks configs for 67 games and 16 dedicated servers.

Ditch the dedicated server; your co-op group is probably paying for empty hours
A 24/7 rented box is great when ten people play every night. For the average co-op group, it's $120–$240 a year of idle uptime. Here's the math, and how Checkpoint64 covers ~90% of the use case for a one-time payment.

Where Steam Deck game saves actually live; inside a Proton prefix nobody can guess
On a Steam Deck, a Windows game's save doesn't sit where the game's own documentation says it does. Proton hands every game a private, Windows-shaped filesystem buried under a numeric folder, and the save is somewhere inside it. Here's the exact shape of that path, why the number is the hard part, and how Checkpoint64 finds it without being told.
-
A Version History App for Saves Gone Sideways
A version history app keeps every game save change, so a corrupted mod, bad boss choice or co-op overwrite cannot erase a weekend of progress outright.
-
Moving a save between your Steam Deck and your PC; the path re-resolves itself
Back up a save on Windows, restore it on a Steam Deck, and those files have to land somewhere completely different — a Proton prefix instead of %APPDATA%. Checkpoint64 works the destination out on whichever machine is doing the restoring, so you never carry a path across. What it deliberately won't do is move your save behind your back.
-
Co-op on the couch; taking the shared world to your Steam Deck without stranding the group
A co-op world lives on one machine at a time, and the moment you want to play it on the Deck instead of at your desk you've become a host with two PCs and a coordination problem. A server-enforced lock turns the Deck into just another seat — take it, play, push it back — without anyone having to ask whose save is current.

The Steam launch is going great; what we're building next
A few days in, wishlists are climbing and the playtest is full of strange, wonderful saves. Thank you. A quick note on how it's going and what comes next.
-
Checkpoint64 is on Steam! Wishlist it and join the playtest
There's now a Checkpoint64 page on Steam. You can wishlist it, follow for the launch, and get into the playtest — and yes, the irony of a save-backup tool living next to Steam Cloud is the whole point. Here's what the listing means and what it doesn't change.
-
Back up the whole folder; the save files your game writes later won't slip through
Picking save files by hand has a blind spot — it never notices the ones your game writes after you set it up. A new farm, a fresh profile, an extra slot. The next build can watch the whole save folder and keep catching whatever lands in it. Restoring got safer too. Here's what's new.
-
Anatomy of a save corruption; what actually happens on disk
Corruption sounds like bad luck, but it's usually one of a handful of very specific things going wrong at the byte level — almost always during the write. Here's what a save file really is, the three ways it gets mangled, and why a single save slot is a single point of failure.
-
The free plan just grew a team; try co-op without a card
Free accounts can now create one team — invite your co-op partner, pass the lock, read the logbook, all without paying. Lifetime quietly went from 2 teams to 3 while we were at it. Here's what changed and why.
-
Cloud saves aren't backups; sync will happily overwrite your good save
Steam Cloud, GOG Galaxy, and console cloud saves keep one copy in sync across your machines. That's not the same as a backup. The moment a save corrupts or a bad autosave fires, sync does its job perfectly and pushes the broken file everywhere. Here's the difference, and why versioning is the thing you actually wanted.
-
The perfect companion for emulators; real version history for save states
Emulators already let you save anywhere. What they don't give you is a history. Checkpoint64 watches the save folder your emulator writes to and turns every save into a versioned, restorable timeline — a rewind button that survives across sessions, machines, and emulator updates.
-
Community servers; host a world, share it with a crowd, keep it pristine
A creator can now host a save and hand out a join code that lets an audience download the world without being able to touch it. No write access, no accidental overwrites, capped and revocable. Here's what read-only members are and when you'd want them.
