SHA-1 CHD Calculation

Post by Proffix » Fri Jun 15, 2018 4:57 pm

Hi there

As seen in Topic is my question.

I calculated the SHA-1 of many files with Romcenter, Romulus und Hashmyfiles and a few more

All with the same Hash but Romcenter was the only one who displays an other SHA-1

Is there a tool which calculates the sha1 like romcenter do?

another solution for this problem where that you can copy and paste the value straight through romcenter..

greets

Romcenter gets the sha-1 from the chd header (see here: http://wiki.romcenter.com/wiki/doku.php?id=chd). It doesn't calculate the full file sha-1 for chd.
This chd should match those of mame. If not this is an issue and should be fixed.

Any hex editor can do the trick.

You're right about the del key. I will map the 'delete' operation like on version 3.
