Redump SNES — A Practical Treatise

This document explains what “redump SNES” means, why it matters, legal and ethical considerations, tools and workflows, best practices for archival-quality dumps, verification, metadata, preservation, and community resources. It’s written for preservationists, retro collectors, and technically minded users who want to create accurate, verifiable Super Nintendo (SNES/Super Famicom) disc/cartridge images for long-term archival and research.

How Redump Dumps a SNES Cartridge

The process of creating a Redump-verified SNES ROM is painstaking:

  1. Hardware Acquisition – A dumper like the Sanni Cart Reader (open-source) or INL-retro-prog is used. These devices read the cartridge’s ROM chip directly via the cartridge slot. redump snes

  2. Initial Dump – The dumper reads the entire ROM address space (e.g., 4 Mbit for Super Mario World, 48 Mbit for Tales of Phantasia). It does this multiple times to ensure consistency.

  3. Hashing – The dumped file is run through SHA-1 and CRC32 algorithms to create a unique digital fingerprint. Redump SNES — A Practical Treatise This document

  4. Verification – The dumper submits their hash to Redump’s internal database. If the hash matches a previously verified dump (from a different physical cartridge), the ROM is confirmed good. If not, at least two more independent dumps from separate cartridges are required.

  5. Release – Once verified, the ROM is listed in Redump’s datfile (an XML file containing names, hashes, and sizes) but Redump does not host ROMs — they only distribute datfiles. Hardware Acquisition – A dumper like the Sanni

Using Redump SNES ROMs

Because Redump does not distribute ROMs, you have two legal options:

6. Submitting to Redump

To contribute to the database, the following data packet is required:

  1. Disc Image: The .sfc file (zipped).
  2. Clrmamepro Dat: The DAT file containing the hash info.
  3. ROM Info String: The internal header info (extracted via uCON64).
    • Game Title (ASCII)
    • Maker Code
    • Game Code
    • Region (NTSC/PAL)
  4. Physical Scans: High-resolution scans (300-600 DPI) of:
    • Front of Cartridge
    • Back of Cartridge
    • PCB (Printed Circuit Board) – Front
    • PCB (Back, if applicable)
    • Box and Manual (for metadata completeness).
