computing a checksum?
Another one of my endless ideas (that I never seem to get around to actually doing). I believe I have access to a full PINMAME ROMset. I'd like to create a checksum file to incorporate into ROMIDENT. Except I don't know how to do that. Is there any easy and straightforward way to create a checksum from a ROM binary file? The only way I know is reading a ROM on my EPROM reader/burner and then having the burner compute it. (Sorry to show my ignorance on all this!). Any guidance/help much appreciated. Thanks, Joe _______________________________________________ Techtoolslist mailing list Techtoolslist@flippers.com http://seven.pairlist.net/mailman/listinfo/techtoolslist
Download ROMSUM from the ftp.flippers.com/TTL site. Does what you need! Thanks to Bill Ung for that DOS based program... Do it like this: ROMSUM *.* >>checksum.txt Then you will get the checksums of all the files in that directory checksums in the file checksum.txt (or call it what you want...).

Hi John, Can you identify where on the ftp site ROMSUM is located? After going to the /ttl site, the only directory (no files) was /test equipment (with no files there either). But there were 19 sub directories. Much appreciated. Thanks, Joe
