Unlike cartridge-based systems, optical media degrades. A scratched or deteriorated disc will dump with errors. Redump ensures:

Note: Redump does not crack or remove protection; it preserves the protection as it exists on the original disc.

Your final 1G1R set should have no "duplicate" titles (e.g., you shouldn't have both Tekken 2 (USA) and Tekken 2 (Europe)). The total count should hover around 1,400–1,600 CHD files depending on your filter strictness.

| Tool | Purpose | PS1-friendly | |------|---------|---------------| | ClrMamePro | Rebuild set from DAT + files, apply 1G1R via “Fix DAT” with region masks | Yes, but complex | | RomVault | GUI + 1G1R mode (fixes missing sets, removes dupes) | Yes | | igir (Internet Game Rom Manager) | Command-line, fast, excellent 1G1R filtering by region/revision | Recommended | | RetroBat / Skraper | For frontends, less precise for pure 1G1R | Not ideal |
