PS3 Disc Dumper is an open-source utility for creating decrypted copies of PlayStation 3 game discs. It helps users extract disc contents into a format suitable for use with compatible emulators, including RPCS3. The application requires a compatible Blu-ray drive capable of reading PlayStation 3 discs. Decryption relies on matching disc keys available through the Redump database, IRD Library, or user-provided files. Users can launch the application, insert a supported disc, and follow the guided dumping process. Extracted files are saved to a configurable output directory. The utility also provides settings for custom decryption keys, local key caching, and diagnostic logs. Built with .NET and Avalonia UI, it supports Windows and Linux environments.
