GOG has two overlapping sets of game IDs, IDs used in the catalogue and IDs used in the library.
For most games the IDs are the same, but not for all, primarily due to unbundling but not only.

You can get all the catalogue game IDs from MaGog. They are in the "Image + Forum + Game ID" column.

The following lists the unbundles/games for which the library ID differs from the catalogue ID.
Format: "library ID" => [catalogue ID, "sort of box title to help you identify the box in question",
Not really sorted, just compiled chronologically, so older unbundles are at the top, newer at the bottom.

P.S. The Witcher 3 already assumes the one box configuration planned for October 5 (not the current three box configuration). Hopefully they will not change the box’s ID again.

P.P.S. For all games, premium editions use the regular edition’s game ID in the library. You're lucky; until last week there were exceptions even for this.

Hope this helps.

Heya. Considering the general state of the GOG, I'd love to help in testing scripts like this. Problem is I really don't know what kind of testing you'd appreciate. What could/should I do?

Hey Agent,
More testers is always appreciated. Basically just install the script, upgrade it whenever there's an update and play around with the new features. If you find any bugs or unusual behaviour, or just think it should be done in a different way just report it here so I can fix / change it.
I try my best to check everything that I think might not work, but I frequently miss things.

Case in point, I checked the new Legacy Remix shelf worked fine, but didn't think to go into detail on the default shelf assuming it would work as planned, so I never noticed the error with the game details windows.
I've figured out what's causing that problem (if not actually why) so hopefully I'll be able to sort it.


Edit: And thanks everyone else for the help with the game boxes for a proper legacy shelf. I'll start looking into that as soon as I can fix these teething troubles with changing how the shelf looks.

This is awesome! I had no idea GOG used a higher resolution image for them, it looks great. I hope this will help Adaliabooks get the boxes back up. Since they are such a good sized resolution I wonder if it could someday be possible to change the size of the shelf for high res displays? Even at 2560x1440, there's a ton of wasted space. I know I wouldn't mind having bigger boxes and a shelf that extends out closer to the edges of a maximised browser. But one step at a time ;)

New update is here!

Just bug fixes mostly for the library style stuff. Hopefully should have sorted all the reported bugs (expect possibly Hyper's dodgy shelf alignment, we'll wait and see on that one). In the normal Default view the game details should now open correctly. The wishlist should no longer be effected (currently I've set it to just modify the game shelf and not the movies, but I may change that once I can properly test it for the movies too).
Refreshes should no longer be required when changing view or when changing style as changing style in the menu now triggers a refresh of the view itself.

As usual please report any bugs here :)

Looks good. ++.
Nothing to report.

Updated. Switched between Default and Legacy Shelf View, switched between Grid and List View, disabled and re-enabled AF:

- Game details open correctly under the game box, in both views.
- No refresh required when switching between views. Not sure what that means. I open my game collection page in a tab using the Legacy Shelf View, and then switch to List View. I change the setting in AF from "Legacy Shelf" to "GOG Default". I go back to my open tab and switch back to Grid View. I still get the Legacy Shelf.
Are you referring to a different action?

- Regarding the Wishlist. There seems to be something wrong with it, but it's more likely a GOG screw up, as it persists even with the script disabled.
The first page displays fine, but the second one is a series of blank entries with a "TBA" price tag. Interestingly, these entries allow me to add them to your wishlist (first screenshot: notice the little heart button instead of the X one).
And if I change the order while on the second page, it forces a page refresh that brings me back to the first one where the blank entries with the "TBA" price tag have spilled over to it (second screenshot).

Funnily enough, Technobabylon showed in my Wishlist (with a messed up "owned+price" tag) which I was able to remove clicking the X button.

EDIT 2: As suspected, it was at GOG's end, thankfully it's been fixed, so Wishlist works as should now. I'm happy to report that each and all game boxes are no longer misbehaving and sit nice and tidy on their shelf. ♪ヾ( ͝°ρ°)ノ♪
I've yet to log off, close Firefox, restart it and log back in to see if it'll still work as should - fingers crossed it won't make a difference.

No idea what you did, or how you did it, but thank you very much!


EDIT: typos

That's what I like to hear :)

Glad everything seems to be working.

Changing the settings in the AF menu will only take effect in the same tab (I think), so in the instance you have outlined you would still need to refresh. But if you have your account page open, go to the AF menu and change the library style, it will change it without needing to refresh (which it didn't before as I hadn't connected the setting to the action yet)

As for the library, I copied GoG's current implementation and instead of displaying one repeated shelf image behind the whole list, each row now get's their own slice of shelf which should mean that they will always align correctly.

There are still issues with different levels of zoom but I doubt that should really be a problem unless someone installs TamperMonkey for Android and uses the script from a phone...

Anyway, looks like it's all working for now... onwards to the next feature! :)

Duh, didn't think of trying this. I'm in the (bad) habit of fiddling around with both the BE and AF settings from the General Discussion page (always log in from this page).

And cheers for the different approach for the Legacy Shelf, now everything works like a charm, thanks again for your efforts!

Looking forward to the next update and feature!

No problem :)

I'll probably try implementing the proper legacy shelf next, now that I have something to work with.

Sounds great!

Do you have an ETA for hiding/disabling the search bar?

I can work on that for the next update too, it will probably take a while to figure out how to do the legacy shelf correctly anyway.

Next update should probably be by the end of the week unless something comes up in the mean time..

*big smile*

Next update is here :)

I've made a couple of small changes to the search stuff (a warning and prompt to cancel a search if it's over a certain number of pages, which you can set; and start and end page searched added to the results block) as well as adding an option to hide the advanced options, and an option to hide the search bar entirely.

Done (ish). I don't think it's a good idea to hide the first / end page boxes as they're some what necessary (particularly on larger threads where it's easy to accidentally the whole thing and freeze up your browser)

Done!
I've just set it to be turned on and off from the menu as I couldn't find anywhere to put a button to show it that didn't look cluttered and out of place.
If anyone objects or has a better idea I can change it though.
