What Does the No-Intro Online Database Catalog?

No-Intro.org's online database catalogs the best available copies of ROMs and digital games, serving as a reference for identifying and verifying game dumps. It is a cataloging and verification resource, not a download site: No-Intro states it does not help or encourage users to download or otherwise obtain any of the listed dumps.

What the database contains

• Entries for the best available copies of ROMs and digital games. The catalog focuses on identifying which known dump represents the best available version of a given game.
• Verification information. Each entry exists so a user can check a file they already have against the cataloged reference data.
• A companion to the DAT files. The online database and the DAT files distributed for ROM managers cover the same cataloging purpose; the database is the browsable, online side of that reference.

What it does not do

• It does not host or distribute ROMs or game dumps.
• It does not provide P2P sharing or download assistance. No-Intro explicitly notes it is not part of the console scene and is not involved in P2P sharing.
• It does not tell you where to obtain a game. The catalog only describes and identifies dumps.

How the database is meant to be used

1. You already have a game file.
2. You look up the corresponding entry in the No-Intro database (or match it with a DAT file in a ROM manager).
3. You compare your file against the cataloged reference to confirm whether it is the best available copy.

The practical value is verification and organization: knowing whether a file matches a known, documented dump rather than an altered or unknown one.

Where to go next

The site points to its Wiki for documentation and its community channels (forums, Discord, Twitter, email) for questions and contributions. If your goal is managing a collection rather than browsing, the DAT files are the relevant part of the project; if your goal is looking up a specific title, the online database is the entry point.
