Valve's Proton downloader for bottles

[tiziodcaio]

We will keep the Proton runner as we still offer both wine-ge and proton-ge. Also, we are working looking for a way to implement and tweak steam proton prefixes directly from Bottles.

I create this issue as reminder, bc it would be useful... I've tested the implementation made into https://github.com/SteamRE/DepotDownloader and it works with the following command after compiling, but it should implement a lot of other libraries and I don't think it would be intersting to us. I write anyway the command used:

# I used Arch Linux, so I simply installed deopotdownloader-git from the AUR, which it pulls the built into /usr/bin folder

depotdownloader -app 1493710 # The proton experimental id dumped from steamdb.info

# Or for the bleeding edge proton with latest implementation of everyone

depotdownloader -app 1493710 -beta bleeding-edge

That's all! I think it would be an intersting implementation even if it takes a bit to download everything and it requires dotnet.

Thanks for reporting, I’ll evaluate this

Sure ^^

I don't know if it would be legal... But I want only try to suggest an idea... a github repository with a workflow that periodically pulls proton from steam servers and pulls them compressed? It would violate the license or can be something that make sense

[mirkobrombin]

It is illegal for sure

[tiziodcaio]

It is illegal for sure

Maybe, its licence is binary redistributable, so maybe if you put valve's credit could it work... But I'm not a lawyer

@mirkobrombin @tiziodcaio Is there a reason to use Proton? GE-Proton builds use Proton as a base already, I think you should get all features of Proton in there, plus some more

I think the only one would be intersting in fact would be proton experimental...

Discovered https://github.com/ValvePython/steamctl , which is much better for our purpose!
