JA2 was actually written as C, and ported to C++ at a later date, once the source became available. While it (usually) is one of the most readable codes I've seen, the documentation of it is sorely lacking...
Ah, good, because so far a first run could only identify 3 games (Syndicate, Cannon Fodder and Ultima 1+2+3), which meant that I'd have to manually enter the rest, something I'd rather not do.
Will wait before parsing the downloads then :)

Yeah, documentation sucks for a lot of code and technologies out there.

It depends the command that you type.

When I distributed your download, there were 3 games in the db (appropriately small games for testing purposes... I didn't want to wait a minute for MD5 computation on large files).

If you use the verify command, it will give you diagnostics based on what is contained in the db (in your version, 3 games), but it won't update anything in the db.

To add more games in the db, you need to use the update command with the -a flag. The last argument is either the directory of your game or "*" to process all the top-level directories in your GOG folder.

For me, it's a slow process as some of my GOG downloads are old and I have to convert the directory structure to be the same as the one generated by the GOG downloader (and make sure the setup files are up to date) first.

Also, currently, the game polls you for a title and whether or not the game requires a CD-key for each game added in the database.

This was fine when I had 100 or so games, but now I'm finding it a tedious process.

I think I'll add the possibility of file input for the update command where you can specify the titles and whether a game needs a CDkey in a file for a whole bunch of games and then you can let the "update -a *" command run in the background without getting polled for info on each new game added.

If you type the "help" command, you'll get more info on the facilities provided by the utility.

k, version 2.1 is out.

Beyond solving the installer naming problem (setup files with different version numbers will now be recognized as being the same file, just with a different version), I added a feature to update a batch of games from a text file with pre-specified titles and CDkey flags.

The file in question is "auto_update.txt".

You basically fill in the info with your games (folder, title and whether or not the game requires a CD-key), then run "update -a" and the loading of unknown games will occur in the background without prompting you for anything.

I'll use it to update the db with all my games.

However, while I own a big chunk of it, I don't own the entirety of GOG's catalog so other people will have to get their hands dirty if you want to have a db containing the info for all the games.

Thank you for the update, grabbing it now, and will start work on the db during the weekend. I do have a large part of the catalogue, so hopefully the missing entries will be easier to fill.

I've been compiling a spreadsheet database based on posts here and the GOG wiki for some time now.

Recently I setup an online repository for people to send me their MD5summer files created directly from their up-to-date collection of games and a list of anything removed since they bought the game - mainly extras.

You can find the files and instructions here:
http://sdrv.ms/10sWGfH

If you want to help, just attach your MD5 file in a post along with the game name and when you last checked/downloaded it. Simples... :)

VERY impressive! Good show!
I will continue to update my files in the original post on a monthly basis (last weekend of the month). Feel free to use it as you wish.

Thanks mate :) Awesome thread .

Over 50 updated MD5's this week.

Still a lot to verify and create hash files for - mainly the new releases.

Thanks!
Added a link to your post from the original post.

Glad to help!

Also, if you wish to add a link to my hash site http://sdrv.ms/UXVDke in your 1st post, please do - I'm sure it will help both of us. :)

Good idea. Did it.

Here's something that should help you:

There are some infos marked with 'nodump' because I don't know of anyone with the games.
Also, some values may now be out dated because I haven't received replies about game updates.
