It seems this project died . Does anybody have hashes now ?

Easy enough if you have the files. Alas I don't have the files.

Hmmm... I COULD easily create a hashfile of all my gog games that I currently have, although it doesn't include a lot of older versions, and the zips are recompressed to be better optimized so they can't be relied on...

I am looking them for check my library between my computers .

Data integrity usually is.

Something you could do... is use the GoG downloader... Having the game in your GoG downloads folder and telling the game to download, it will skip files it verifies have no problems.

However that isn't a hash/source you can check later if for some reason the internet is down.


You'll probably be stuck waiting on someone who has the files and knows how to md5sum the files.

Doesn't GOG provide md5 checksums to at least most of its games (the installers, extras don't have them but then you can check their zip file integrity by other means...)?

At least gogrepo.py is somehow able to get md5 checksums from GOG servers for the games. When you run "gogrepo.py verify", it will check all the GOG game installers in your collection against their md5 checksums. For extras it checks the zip file integrity instead, and for those few installers that don't have md5 checksums for some reason, it merely checks that the size is correct.

On the other hand, if you just need to check that a set of files/subdirectories are identical in two different places, you could also use some small utility like dvdsig.exe or rhash.

I've run the md5sum on my gog library. Maybe if you have another you wanted to check you can do a quick confirmation.
