I checked this out, but it does a chexsum on the complete ROM image, not on
a single data line of a ROM, so it doesn't give 8 results per ROM, that are
the same as the Atari published ones.
Similarly, it doesn't tell you what algorithm it uses. It looks to be a 16
bit one, though. ROMIdent uses 32 bit, which pretty much does the same
thing.
