Hi all, I'm pretty sure the answer to this is no, but did anyone ever work this one out? Ie how to calculate the sigs from ROMs? It's never really been a show stopper for me since I check against the CRC32 sigs first thanks to a script that Andy Welburn posted up some years back (with assistance from Chris Hardy I believe?) and then when I know a ROM matches and the fluke can read it in-circuit ok I then use the 9100 to get the 9100 sig. It's a bit of a drag though as the CRC32 calculation is kinda slow (even on the FT) so it would be nice to have the 9100 sig up front.

Hi Martin, Yes, that was worked out and made into a nice utility program that you can download from Quarterarcade (a big THANKS to James Bright for this work!) @ http://tech.quarterarcade.com/tech/Fluke/9010A/ The FIDE software allows you to input your files that you want ROM Signatures and it does the rest.

Hi John. Unfortunately that's all for the 9010. I'm talking about the 9100 and the sigs are different. Martin On 26 Aug 2010, at 00:49, John Robertson <jrr@flippers.com> wrote:

Ah, right - didn't the 9100 just use regular checksums for its 'Signatures'? In which case there is RomSum.exe that will generate checksums for individual files or entire directories, printing the results to screen or piped to a file. John :-#)#

It doesn't seem so, no. I just went and read in 'galtest.bin' the (or a) galaxian test rom. Here's what I get (the first ones are various CRCs my programmer can produce): The layout will probably be messed up so sorry about that. Sum Neg. Suppl.

I grabbed RomSum from a link on the flippers site so I assume it's the one you're talking about? Apologies to those on the list who are not here from the arcade world! I'm going to go investigating further. Martin.

I did a dump of the signature Rom generation code (using an Arium ML4100 as I recall) to help figure out what the Fluke 9010 signature was...check the archives back in 2002 - Oct and later first under "Signature" then under "Cracking" for the subject line. John :-#)#
