Hi, This is a semi-repost of my post on the Gog Galaxy 2.0 forum - but kinda hoping more people might see it here and use the same self-hosted services.

I've got a gaming machine but for reasons of time and work etc, I am often away from home.

I've set up Sunshine streaming service on my home PC (complete with WOL and networking/vpn etc). Its a non paid for self hosted service.
I use Moonlight streaming client on my reasonably decent laptop.

This allows me to stream games from my home pc to my laptop anywhere in the world as long as i've got power to my home pc, power to my laptop and an internet connection either side.

Great...so why are you posting this on GOG you ask.

Simple:

In Sunshine you configure apps creating a config for them.

On Epic game store (bleugh...) you can launch "Surviving Mars" from a nice gui menu inside the Moonlight client streaming right into your client with the following easy config.

Name: Surviving Mars
Command: com.epicgames.launcher://apps/d759128018124dcabb1fbee9bb28e178%3A20729b9176c241f0b617c5723e70ec2d%3AOvenbird?a ction=launch&silent=true

or in Steam:
Application Name: Surviving Mars
Detached Commands: steam://rungameid/464920

how this looks is it launches epic game store or steamand then launches the game with no messing about in the launcher but you benefit from the full features of havig launched it from within the platform (cloud sync/saves etc)..

Now i can run some games directly by calling the binary:

Application Name : Surviving Mars
Command: MarsSteam.exe
Working Directory: "C:\Program Files (x86)\Steam\steamapps\common\Surviving Mars"

my Gog version of NWN:EE works with this:

Application Name: NWN:EE
Command: nwnmain.exe
Working Directory: "C:\Program Files (x86)\GOG Galaxy\Games\Neverwinter Nights Enhanced Edition\bin\win32"

But it doesn't display quite correctly in terms of resolution - nor am i certain cloud saves would work as i haven't launched it from Gog Galaxy... The game itself works great however.

So is there anyway to launch Gog Galaxy from Sunshine itself and then launch a game (such as the steam example above with a URI). This would be idea to get the full features of gog galaxy whilst still running the game.

Thanks for all your time and patience those that have read, this is not a criticism of gog or gog galaxy - i love the platform and have quite a number of gog games, many of which i am more likely to play if i can get this to work - so i simply want to know if this is possible to do and if anyone has done it if they could provide a sample config for a gog game or the gog app.

Thanks. :)
