Modern emulators (like bsnes) require perfect, un-mirrored dumps to function accurately, particularly for games with specialized enhancement chips. 4. How to Verify a Redump SNES ROM
Preservationists use specific burning software and hardware to dump a disc multiple times. If the cryptographic hashes (like CRC32, MD5, and SHA-1) match across different dumps from different users, the dump is verified as a "perfect" copy of the retail retail disc.

The SNES utilizes a 16-bit checksum stored in the header. Historically, "Bad Dumps" occurred because the ROM on the cart did not match the checksum due to bit-rot, or conversely, the checksum was calculated incorrectly by the developer.
Many SNES games had subtle, unadvertised changes during their production lifespan (e.g., bug fixes, changing the "Nintendo" logo, or removing flash-memory save bugs). Redump catalogs these variations, assigning each unique dump a specific hash. 3. Emulation Accuracy

To redump correctly, one must understand that the SNES does not address memory linearly like a PC.
