Preserve ROM hacks
without the upload.
Hash a hack in your browser, submit the fingerprint, and let the community verify it. A No-Intro-style DAT built on trust, not anti-cheat.
Select or drop ROM files
Hashes computed locally — the ROM file never leaves your browser
Privacy guaranteed. ROM files are processed entirely in your browser. Only the resulting metadata — filename, file size, CRC32, MD5, and SHA-1 — is submitted to the database. The ROM binary itself is never transmitted.
From local hash to verified entry
Hash locally
Drop a ROM in your browser. CRC32, MD5, and SHA-1 are computed client-side — the file itself never uploads.
Submit metadata
Attach hack name, author, version, and source. Only the generated hashes and details are sent.
Community verifies
Other holders of the same ROM confirm matching hashes. Trust-weighted votes build a verification score.
Admin approves
Once thresholds are met, an administrator merges the entry into the master DAT for export.
