No-Intro DAT Matcher
No-Intro DAT Matcher is a free Linux script for organizing ROM files against No-Intro or Redump DAT files.
What No-Intro DAT Matcher is
No-Intro DAT Matcher is a free Linux script for organizing ROM files against No-Intro or Redump DAT files. It hashes files and compares the hashes with DAT entries, then copies or moves matched ROMs into an output folder using the DAT filenames. It can skip files already in that folder and writes missing ROMs and unmatched files to a text file, which can help identify gaps in a collection. The README directs users to get DAT files from DAT-o-MATIC or Redump. The instructions require Python 3 plus the xmltodict and tqdm packages. For NES files with an iNES header, the filename must end in .nes; the script skips the first 16 bytes when matching. N64 collections may require both Byte Swapped and Big Endian DATs, and the README mentions tool64 for converting ROM formats. The maker warns that hashing large disc-based games can take a long time and suggests moving rather than copying when disk space is limited. The repository provides the software under the MIT License, as is and without warranty.
Good
- Matches files by hash against DAT entries.
- Can copy or move renamed files.
- Reports missing ROMs and unmatched files.
- Can skip files already in the output folder.
Watch out
- Requires Python 3, xmltodict, and tqdm.
- Hashing large disc-based games can take a long time.
- NES iNES files must end in .nes.
- N64 users may need two DAT variants.
Who it suits
This script suits Linux users organizing ROM collections against No-Intro or Redump DATs. It is for users comfortable installing Python packages and working with DAT files.
Verdict
No-Intro DAT Matcher provides hash-based ROM matching and file renaming for Linux collections. Account for its Python dependencies and the maker’s warning about lengthy hashing of large disc-based games.
