Click Play to watch a 90 seconds screencast of GitUp in action
GitUp lets you see your entire labyrinth of branches and merges with perfect clarity.
Any change you make, large or small, even outside GitUp, is immediately reflected in GitUp's graph. No refreshing, no waiting.
Highlight a commit and hit the spacebar to quickly see its message and diff.
GitUp gives you full, transparent control over your local checkout, so it's easy to back out from unwanted changes.
Margaritas, tattoos, sudo rm -rf / …some things in life can't be undone.
But GitUp makes undoing your latest changes as easy as cmd-z.
GitUp's Snapshot feature builds a Time-Machine-like history of every change made to your repo, allowing you to step backwards to any point in time.
Rewrite, split, delete, and re-order commits, fixup and squash, cherry-pick, merge, rebase—It's all here, and it's lightning-fast.
GitUp puts the power in your fingertips.
Surf your repo, make changes, and rewind it all back with a few short keystrokes.
You're here to write code, not meditate on arcane Git incantations.
These tools automate what would otherwise be an impossible manual task: ensuring that thousands of ROMs all match Redump's strict specifications. They can scan a user's folder, identify missing or incorrect files, and even rebuild corrupted ROMs if enough reference data is available.
The easiest options are devices like the or the SN Operator . The Retrode 2 mounts as a USB drive, allowing you to dump ROMs without special drivers. The SN Operator is a more modern device that can dump games, back up save files, and play original cartridges on a PC.

Whether you choose a pre-built Retrode or enjoy the challenge of a DIY Arduino project, the effort to dump your games to the Redump standard is a rewarding way to become an active participant in the history of video games.
Preservation Through Verification: A Comprehensive Technical Guide to Redumping the Nintendo SNES/SFC Library These tools automate what would otherwise be an
Unlike older projects that focused on making a game file as small as possible for early emulators, Redump’s goal is absolute data integrity. The project aims to create a digital "blueprint" of the original media, striving for a copy that is as close to a 1:1 duplicate of the original cartridge as technically possible. This is achieved through community collaboration: multiple users dump the same game, and their checksums (cryptographic hash values like SHA-1) are compared. Only when several dumps match perfectly is a game marked as "verified".
This extension dates back to the 1990s, named after an early floppy-disk-based copier device. .SMC files often contain an outdated 512-byte header. While many modern emulators can still read them by automatically stripping the header in memory, they will fail verification checks against modern preservation databases. How to Verify Your SNES ROMs The Retrode 2 mounts as a USB drive,
As the progress bar reached 98%, the hum of the drive changed. A "read error" flashed. In the world of Redump, an error wasn't just a glitch—it was a tragedy. It meant the data had been "hacked" or corrupted over decades of storage.
Redump.org is a disc preservation project and database dedicated to archiving video games. Its core philosophy is simple:
