drop any ROM file to compute its hashes
how to use
· Drop your ROM — CRC32, MD5, SHA-1, and SHA-256 are computed locally in under a second for most ROMs.
· Compare the CRC32 or SHA-1 against No-Intro, Redump, or GoodTools database entries to verify ROM integrity.
· SNES ROMs with a 512-byte copier header (.smc) get a second set of hashes after stripping — the No-Intro database uses the stripped version.
· Click any row to copy that hash to clipboard. "Copy all hashes" copies a full report.
