Done! At launch the game was without achievements, so I added it to the list, but since there are now so many games on the list it's very easy to forget to update some of them.

Is this a bug that only occurs during pop-ups? Anyway, yes, let us know if you notice anything strange.
Excellent, surely there are games with broken achievements among them, but we need official proof because they may simply be very difficult or unlocked by so few people that they don't even reach 0.1%.
Thanks already done, see previous posts.
A Hat in Time had a similar bug, but they fixed it fortunately. Do you know if other people have reported the same problem?

When I mentioned it the first time, someone told me that on Steam it acted the same way and restarting Steam would help. That didn't do the trick however.

But nvm, it seems that it has been fixed with the last patch.
I'll just have to replay everything :s Seems I have use for that handheld after all.

EDIT: The achievement was removed.
Legends of Amberland II has an achievement for killing 10,000 monsters, which is equivalent to killing all monsters in about 5 playthroughs. The dev has admitted on Steam that the achievement is not coded into the game and is unachievable.

Ghostrunner 2 Demo had Features: Achievements on the store page. Is it true that it never had any?
Shame. Shame!

It's one of the many errors of GOG game tags unfortunately, the demo never had achievements, even on Steam or other stores.

its interesting

Okay, after investigating, there should be a simple fix for the broken achievements for The Dream Machine. I took the SteamWrapper.exe from The Gateway Trilogy, and used it for The Dream Machine. I also added some information to the SteamWrapper.ini file that was missing. You can download the two files below, extract and replace the ones in your installation directory, and they should work. I'm going for a 100% run to test it, but I am confident all achievements for The Dream Machine should be working after this.

Edit: BTW, it's 75% off right now, I recommend buying and playing it, it's probably my favorite adventure game on GOG. :)

That's a spam bot. It duplicated SCPM's post.

Edit: typo.

This is great, I had given up hope when the developer completely stopped caring about the issue despite many requests. Thank you!

I'll still try to point out this solution to him in the remote case that he wants to implement it officially.
Damn, this forum is getting really ridiculous with the omnipresence of bots of all kinds. Forestwen above is another one of them.

I already did this on Steam.

Perfect, thank you!

The latest update for Soducats broke achievements. I already told the devs but since I also noticed that they are using the same GalaxyConfig.json file the devs from Beautiful/Sexy Mystic Survivors are using and they were able to fix the problem by editing the config. I decided to try the same "fix" here as well and it worked. Achievement popped even retroactivey.

Edit GalaxyConfig.json and first add "," at the end of the last line in the config. Then coply the following lines

the following line:
"is_unity": true"

Achievements should work now :)

Edit: Should have been fixed with the recent patch. So this workaround should not be needed anymore.

As promised here's my report:

1. Broken Images
If you check my unlocks, you could notice only one broken image, but there are more, they are hidden behind Secret achievement (a stupid concept btw) icon, but they are visible when I look at my unlocks (check attached pic).
Anyway, the following GOG achievements have broken images:
- I'll Be Back
- Thermal BOOMing
- Look At You, Snacker

This is a GOG thing, these chivos don't have broken images on Steam.

2. Bugged Achievements
- The Inside Scoop
This one pains me greatly...it's for collecting all Audio Logs and Data Sticks. I collected them all but didn't get the achievement and here's way (99% sure). The total amount of media you can collect is 150, used to be 151 before the patch, but there was a duplicate Audio Log in Flight Deck that they removed. The fuck up is, once they removed the duplicate this achievement (that was working before) stopped from triggering at 150. I even collected a bugged Audio Log that's hidden behind a wall(!!!) but alas, didn't do me much good achievement wise. :(
- It's Over
Some sources say that this one should pop up after watching the end credits, but that's bollocks, this chivo has been broken from the release and nothing you could do in-game can change that at the moment.
- I’ll See You Again, Hacker
This one is for getting all other achievements, but since the above one could never be obtained, that also makes this one unobtainable.

If it's any consolation, these bugged achievements are not a GOG thing...the exact problem exists on Steam as well. So, if they ever decide to fix the chivos there with a patch, they will probably do so here as well.

Recent Sudocats update name says it all:

"Download changed: Installer, Sudocats, Windows, en
Version 1.1 (random puzzles, with GoG Wrapper) ⇒ 1.11 (json achievements fix), Size 212.9 MB ⇒ 212.9 MB "

I guess it is safe to say that Sucocats achievements are working again :)

Nice. The devs are really great. I sent them in the past an email because the daily puzzles were broken and they fixed it very soon and also sent me some cat wallpapers as an apology. I recommend people to support them because they have some nice interesting games which are also not very expensive. :)
