I've tried to show this game to a friend on Discord. Unfortunately, the app doesn't recognize the ScummVM window.

Is there a solution where I could somehow stream the fullscreen game - like all other games?

I have never streamed a game using Discord, but maybe you have luck if you tried with a recent version of ScummVM?

GOG Blade Runner ships with ScummVM 2.1 but currently ScummVM's latest version is 2.6.1 (stable) and 2.7.0git (daily development).

Since a few releases ago, ScummVM started using an OpenGL rendering mode by default, whereas in version 2.1 it used SDL Surface mode which might have complicated video capturing(?).

I use OBS Studio to capture video from ScummVM these days and at least with the latest versions (both OBS and ScummVM) I don't have any issues.

Discord seems to have an issue with this particular game window. I know in OBS I can choose the target .exe from the game capture, but in this instance I want to show the game in Discord - which wouldn't allow me to choose that window as a valid source. :/

Edit: I've found a workaround. Enabling the Discord Overlay for Blade Runner seems to force it to choose the game window for streaming. Works for me now

Good to know you got it working.

I would still suggest playing the original or restored content mode with the latest ScummVM version possible (currently 2.6.0) since it includes bug fixes, improvements and (some) content updates. Plus, we could use the feedback to improve it even further :)

How would I do that? Unti lnow i was basically just clicking the shortcut on my desktop to launch the game. ScummVM starts alongside but i haven't interacted with it before

ScummVM can be installed centrally on your PC like other applications and you can add multiple games to it by pointing to their respective installation folders.

Or, it can operate like on GOG's ScummVM bundled games, which basically have ScummVM extracted in a "scummvm" folder inside the game's installation folder.

So, one simple solution would be to:
1. backup the current "scummvm" subfolder of Blade Runner (ie. rename it to "scummvm-2.1"),
2. download the zipfile for the 2.6.1 stable version of ScummVM for your system (eg. "Windows zipfile (64 bit)") from the ScummVM website,
3. extract the zipfile inside the Blade Runner folder; it should create a folder like "scummvm-2.6.1-win32-x86_64" which you then have to rename to "scummvm" just as GOG expects it to be.
4. Run Blade Runner from the GOG shortcuts just as before. It should now use the new version of ScummVM.

Basically, this is like overwriting your old "scummvm" folder with a newer version of it. Which is why I suggest keeping a backup so you can switch back if you want to -- for which you could always re-install the game, but that's more of a hassle.

Another suggestion would be to make a central installation of ScummVM, for which you'd need the installer for ScummVM 2.6.1. (eg. "Windows Installer (32 and 64 bit)"). This would require a bit more interaction with ScummVM, though, since you then will have to add your games to the ScummVM launcher, optionally customize the configuration options for them, and also optionally use other ScummVM features (game engine options, cloud saving, and soon (in the next version) graphics shaders). It's not hard to familiarize yourself with ScummVM, and there's lots of documentation for it -- and a forum and a discord if you need more help -- but you can always choose the first suggestion if this one sounds complicated.

I should also note that if you're using subtitles, we periodically update and fix those too. Currently they are at version 8. I believe when GOG released Blade Runner, we had them at version 2.

I tried the new version and it launches flawlessly as you described in the first method - including streaming on Discord (after manually toggling game overlay to on). Subtitles seem to work nicely as well!

I wasn't aware about any bugs in the previous playthrough, but that might have been me being lucky.

Thanks for you support and I'll check out the ScummVM project more closer!

Ps: I checked out the .ini and stumbled upon "sitcom" mode. Checked ScummVM documentation and found some hillarious settings for BR :)
