The No-Intro project is the modern gold standard for ROM archiving.

Many people think they have a full set, but they don't. Here are the most common issues:

No-Intro's mission statement is simple: They focus primarily on cartridge-based media and maintain a strict database (DAT) of what constitutes a perfect, verified ROM dump. This has become the gold standard for SNES, NES, Genesis, and Game Boy collections.

Start small. Take your personal cartridge collection, dump five games, verify them against the No-Intro DAT. Once you master that workflow, you’ll be ready to scale up to the full verified library. Happy archiving.

: For users specifically looking for North American releases, the SNES USA Complete Collection provides a single compressed archive of the ~717 official regional titles.

Verified ROMs ensure the game works perfectly on accurate emulators, preventing glitched graphics, audio issues, or random crashes. What is Included in a Verified SNES Archive?

When a cartridge is dumped, software calculates its hash value. This value is compared against an official database. If the numbers match perfectly, the ROM is verified. A basic checksum used for quick error detection.

A stronger cryptographic hash widely used in older databases.

When building an archive, you will encounter two primary standardization systems. They use completely different philosophies for organizing games. The No-Intro Standard (Recommended)

: Standard SNES ROMs use .sfc (Super Famicom) or .smc (Super Magicicom) extensions. The .sfc format is preferred by modern emulators.
