As long as you type a ":" instead of the ";".
Is supposed to work like this, yes.
Should be irrelevant, as long as PATH or LD_LIBRARY_PATH aren't set to include locations where incompatible binary/library versions exist, and are found first.

Here goes nothing, then.

I don't know how to check whether the "486/586/686 files" are in place or not, but I worry about it later if the movies still don't work with the game. At least it told me "gstreamer-32bit" is already installed, when I tried to install it. In case that is the package/libraries needed by the WMV videos in that game.

"Ancient" Debian here:

Version 0.10 is REALLY old, and might in fact cause errors if still present; you should have something > 1.0.

There should be a directory for AMD64 files and another for 32-bit files below /usr/lib.

On Debian type systems those are called:

/usr/lib/x86_64-linux-gnu
/usr/lib/i386-linux-gnu

Note that the name "i386" hasn't been changed on Debian, but is not true any more, most distributions require at least a 586 type processor nowadays, if not 686, but that doesn't matter, because you have a 64-bit system anyway. I'm writing this, because your RPM system might have another naming scheme.

I guess it would have been to easy if it had worked just like that. The game launch aborts with an error, backtrace (which doesn't really tell anything to me, not sure what to look for):

Unhandled exception: page fault on read access to 0x00000000 in 32-bit code (0x0064553d).

I guess I need to google how it is set up in OpenSUSE.

I don't see similar directories under /usr/lib/, but I noticed I have both /usr/lib/ and /usr/lib64/, not sure what that means...

I do have e.g. this:

ll /usr/lib/gstreamer-1.0/
total 688
-rwxr-xr-x. 1 root root 577216 Oct 16 20:56 libgstcoreelements.so
-rwxr-xr-x. 1 root root 124460 Oct 16 20:56 libgstcoretracers.so

Gemini AI claims:

"On openSUSE,
/usr/lib is for architecture-independent or 32-bit libraries, while /usr/lib64 specifically holds 64-bit libraries. This separation allows for the coexistence of both 32-bit and 64-bit applications on the same system, which is often handled by multi-architecture development toolchains. Some older distributions may have symlinked /usr/lib64 to /usr/lib for compatibility, but openSUSE uses the dedicated /usr/lib64 to clearly separate the two, with /usr/lib containing architecture-independent components."

To "uninstall" the WINE game, is it enough to just remove that prefix directory, and any shortcuts in the desktop the installer may have created? Since it is the only game under that prefix anyway.

Yes, since the registry is just made of text files inside that prefix, deleting a whole prefix removes almost everything of that particular "virtual Windows installation". Apart from shortcuts on the desktop, there might exist files in ~/.local/share/applications or in the menu: ~/.config/menus as well. If the installer is a normal Windows one, and not specifically made for Wine on Linux, it won't put anything into /usr/local or /opt, for example. If the Windows installer wants to put something onto the Windows desktop, or the start menu, those files will normally be "redirected" to the analogous locations of your desktop environment. %TEMP% and similar folders are normally left in their normal locations inside the prefix. The details depend on the setup of the Wine package you are using.

You can call "wine winecfg" "from inside" the prefix, there should be a "desktop integration" page, where you can look up the "redirected" folders (EXCEPT the menus, on my Debian installation there's a "Wine" entry for the start menu of the default Wine prefix at least).

Please keep generative AI crap out of this thread.

The AI techbros have been actively trying to kill ./play.it for months (good thing they are dumb as bricks, or we would no longer be online), there is no way they could be welcome here.

I tried the same manual Sacred Gold wine installlation steps on a Linux Mint system.
There at least the game runs, but still without the videos. So basically the same story as in OpenSUSE, installing the game with either Lutris or Heroic. So yeah, something is still missing specifically for the WMV videos.

Is there some generic GOG Linux thread? I'd rather not spam the play.it or Adam Wrapper etc. discussions with generic discussion about getting GOG games to run on Linux.

Gstreamer is modular, it doesn't do much on its own unless you have the right plugins for playing media installed. Wine bug thread says to make sure you have correct 32 bit plugins installed, which is not the same as having 32 bit Gstreamer installer.

I'm on Debian 13 and just checked that 32 bit plugins are not installed by default with Wine. I would guess it's no different on Mint. Try installing i386 versions of these packages:
gstreamer1.0-libav
gstreamer1.0-plugins-good
gstreamer1.0-plugins-bad
gstreamer1.0-plugins-ugly

Though first two should make you covered in 99% cases. If this works, find how to install analogue packages on Opensuse.

Thanks, I'll try that first on the Linux Mint system.

Is there some error that points to that solution, or is this something you just have to know, like:
"WMV videos don't play" => "they need gstreamer libraries and specifically plugins" => "this particular game needs 32bit versions of those, not 64bit" => "to install 32bit thingamalings for 32bit gstreamer, you must install the aforementioned plugins manually" ?

I am also wondering that if the solution turns out to be that easy, why the Lutris installation script etc. doesn't install those needed plugins, or at least mention that they are needed?

When I tried to google for this, it was very hard to find any concrete information. There were certainly reports of the videos not playing in this game but no clear solutions for it, which lead me to believe that's the way it just is, it is impossible to get them to play on Wine.

Some comments claimed the game wprks perfectly in WINE or ProtonDB or whatever, but no idea if that meant the videos played fine too, since many people seemed to have much bigger problems than mere skipping videos, like that the game would not launch at all but they'd get only a black screen.

This is all still quite confusing to me, getting right libraries for some old 32bit Windows games (in WINE), and getting Geforce drivers to install correctly, always seem to be the biggest hurdles for me in Linux. Everything else seems so easy compared to those.

It's been pretty much the standard way of making videos in Windows applications play for years. Nowadays it might be less obvious since I believe Proton has some most common or tricky codecs for games baked-in, and many people are shifting to that.

As for Lutris, I wouldn't give them too much credit frankly. I recall trying their script once for some problematic game years ago, and it didn't work either, I had to tinker myself. Possibly they are just using a generic install script nobody ever looked into to fine-tune it, or it was never updated after the supposed fix in Wine. After all, this is a rather niche game these days I imagine.

If it still won't work though, perhaps the bug should be reopened. There could be a regression along the way.

I found the solution to Sacred Gold (GOG-version) videos not playing: install WMP9 with winetricks. WMP9 = Windows Media Player 9 (codecs).

I did this within Lutris since I already had the game installed with it. Sorry if someone already mentioned this in this discussion too, I didn't even know before this the meaning and importance of winetricks.

I am unsure though if that alone is enough because in the meantime I've been installing every 32bit gstreamer plugin to Linux, thinking they were the culprit, so now I am unsure if they were needed in this case or not. I practically ran "sudo zypper install gstreamer*32bit" (for OpenSUSE) so that it installed everything where it finds strings gstreamer and 32bit. It sure installed a bunch of stuff, not sure now if in vain. Doesn't matter because I am thinking of replacing this laptop's 512GB SSD with a 1TB SSD that I have lying around unused, and re-install both Windows 11 Pro and OpenSUSE Tumbleweed to it from scratch, so I will test again whether those additional 32-bit gstreamer plugins are needed in this case or not.

Anyway, at least that missing WMP9 codecs within the Wine prefix was one of the reasons the videos didn't work within the game. When you run the GOG installer with wine or Lutris, at the end the GOG installer apparently tries to install WMP9, but fails with a generic error. So i guess now winetricks installed what the GOG installer couldn't, in Wine.

It’s to avoid that kind of problem that all ./play.it scripts are lovingly hand-crafted, and my work in recent years had a focus on preventing them from falling behind regarding maintenance.

Of course it comes at the cost of a much smaller number of supported games, but this is always going to be a downside of artisanal work. I try to compensate that by making it as easy as possible to add support for new games, so the step from ./play.it user to ./play.it contributor is not a big one.
