Redump ^hot^ Jun 2026

Without the strict guidelines established by Redump, thousands of rare video game variations, revisions, and regional exclusives would be lost to history. The project ensures that digital archivists, historians, and museums have access to the exact data printed on the plastic millions of years ago—or rather, decades ago.

Both groups also publish "DAT files," which are essentially text files containing all the checksum information for a given set. These DAT files are used by ROM management software (like clrmamepro) to organize and verify game collections. redump

This commitment to verification means Redump prioritizes accuracy over speed. As of 2025, the project has cataloged and verified nearly 150,000 disc images across 40+ systems, from the Sega CD and PlayStation to obscure platforms like the PC-FX and FM Towns. For each entry, the database holds not just the image but a detailed log file of the dumping process, photos of the disc and its ring codes, and the exact offsets of the data. This is archival at the level of paleography—treating each disc as a unique artifact with its own material flaws and manufacturing signatures.
