The Super Nintendo Entertainment System (SNES), released in 1990 (as Super Famicom in Japan), represents a pivotal era in 16-bit computing. Unlike standard optical media, SNES cartridges contain various integrated circuits (ICs), including mask ROMs, volatile RAM, and specialized coprocessors (DSP, Super FX, SA-1).
The historical standard for SNES preservation was the "GoodTools" (GoodSNES), which focused on playability and ROM management. However, the Redump standard prioritizes bit-perfect archival images. The primary distinction lies in the retention of header data (where applicable) and, crucially, the verification of unused data areas (blank padding) and internal checksum consistency. redump snes
The process of creating a Redump-verified SNES ROM is painstaking: The Super Nintendo Entertainment System (SNES), released in
The Redump SNES project relies on contributions from the community, including: Packaging formats:
Before focusing on the SNES specifically, it’s important to understand Redump itself. Founded in 2007, Redump is a collaborative, global community project with a simple but ambitious mission: to dump every commercially released optical disc and cartridge-based game in the world, bit-for-bit, without error or alteration.
Originally focused on CD-based systems (PlayStation, Saturn, Dreamcast), Redump later expanded to cartridge-based consoles like the NES, Genesis, and of course, the Super Nintendo Entertainment System (SNES) .
Redump’s methodology is what sets it apart. They do not accept ROMs downloaded from shady websites. Instead, community members use specialized hardware (like the Sanni Cart Reader, Kazzo dumper, or Retrode 2) to read data directly from genuine cartridges. Multiple dumps of the same game are compared, cross-referenced, and hashed (using CRC32, SHA-1, MD5) before being released as “verified.”
