The filename doesn't tell you everything you need to know. You can run into bad dumps, overdumps, corrupt files, mislabeled files, and more.

Hashing is like a form of fingerprinting for data. Checking the hash of a file helps you determe whether you have exactly what you're looking for. provides a hash for both the whole file and the raw ROM image contained inside the file, plus some additional data, to help you figure out whether you have the right thing in the right format.
