Redump Snes //free\\ -

Redump.org: A disc preservation group focused on creating 1:1 "perfect" backups of optical media (CD, DVD, Blu-ray) for consoles like the PlayStation, Sega Saturn, and GameCube.

1. Game owners: Individuals who own physical copies of SNES games contribute to the project by creating and sharing high-quality ROM dumps.
2. Validators: Experienced members of the community verify the accuracy of submitted dumps, ensuring they are free from errors and corruption.
3. Metadata contributors: Participants provide detailed information about each game, including title, release date, and technical specifications.

• Dual-chip games (DSP-1, SA-1, Super FX, CX4) — Redump dumps the ROM portion; special chip data is often handled separately.
• Satellaview (BS-X) games — Broadcast-downloaded titles that require additional work.
• Famicom Disk System (FDS) — Though not SNES, Redump has expanded into disk-based Nintendo media.

At its core, the "Redump SNES" initiative is a technical standard, not a public archive. The term "Redump" refers to a global, collaborative community dedicated to creating verified, 1:1 digital copies of optical and cartridge-based media. For the SNES, this is a uniquely challenging task. Unlike a CD-ROM, an SNES cartridge is not a stream of raw data but a complex piece of hardware. A cartridge can contain various logic chips, enhancement chips (like the Super FX or SA-1), and multiple memory mappings (banks). A simple, naive dump—reading the ROM as a flat file—often produces an incomplete or corrupted copy, missing crucial header data or interrupt vectors. The Redump methodology addresses this by demanding dumps be verified against multiple copies of the same game revision, using specialized hardware (like the retrode or Sanni Cartridge Reader) and software that accounts for the cartridge’s internal wiring. The goal is a "perfect" ROM: a digital twin that, when run through an emulator or FPGA device, behaves indistinguishably from the original silicon. Redump

4. Step-by-Step Redumping Procedure

Phase 1: Physical Preparation

1. Inspection: Open the cartridge (using a 4.5mm security bit) to identify the PCB type. Note the chip markings (e.g., "SHVC-1A0N", "GSU-1"). This is crucial for games using DSP or Super FX chips, which may require specific dumping scripts.
2. Cleaning: Clean the edge connector with isopropyl alcohol (99%) to ensure a stable electrical connection. Intermittent connections cause bit-flips, leading to bad dumps.

  1. Dump Your Own Cartridges

  Using a Sanni Cart Reader ($100-$150) or Retrode 2, you can dump your personal SNES collection and verify them against Redump’s DAT files using tools like ClrMamePro or RomVault. This is the purest legal method. Game owners : Individuals who own physical copies
