Nucleus Coop support in Proton for Steam Deck

[ClarkDiggity]

Nucleus Coop allows split screen play for hundreds of games. This would be a great application to add support for on the Steam Deck. I personally would like to play COD Black Ops 2: Zombies with four split screen players.

Edit: I would be using the deck docked to a tv.

This sadly has already been asked of the Nucleus Coop devs and they said no

well then it's not happening

Edit: Nevermind

Not necessarily. If Proton were to add support for the Windows API calls that Nucleus Coop is dependent on, then Nucleus Coop would work, so Valve is able to make Nucleus Coop work on the steam deck.

Oh, so proton would basically have to become a windows emulator 😂
Nevermind then. I guess its back to badgering the nucleus co op devs! (im joking, dont actually do this)

it's probably way easier to recreate nucleus in Linux. launching the games is the easy part, just use various steam emulators for the fake local steam network (like nucleus does), I guess the controller assignment is the harder part.

So the reason why is because it would:

a) require a huge amount of time to rewrite their code to work with linux and hey do not believe it is worth the time and effort to do it (id imagine as a small team - especially if it has all different dependences and coding language use)

While I can get it to run in proton through compat where it drops its files after installing & I can copy my game over and it can locate the exe for the game (which is sepeate to steam, I also tried turning on spoof steam) throws an error after the loading splash screen of nucleas coop with loading player 1 of 1 - then it cant find the process and crash when I try to play/launch splitscreen with SWBF2 (og).


to put it in perspective to how proton works from my experimentation - something simple like GTA Connector works with the 1.0.8.0 patch exe but that required me to drop my game files to that same folder it is running from as it is like a sandbox.

some programs might work but its a gamble.
So unless theres a huge dedicated team to help them port to linux or someone extremely enthusiastic and determined to convert the source code to generate a Linux port - we can only do so with windows.

I would strongly suggest running windows on a fast sd card because i find i could bsod my win11 and it wanted to update. but importantly to test performance. fortunately resident evil 5 has officially added splitscreen coop but for others yeah).

The way nucleus works is it launches multiple game copies using steam network emulators. My guess it that the features that are not easily portable to Linux involve the controller support, but I never checked to know for sure.

Have you been able to find anything on this? I can't get the Linux alt to work and would like to try this aswell for borderlands 3

You do realize that the Steam Deck isn't powerful for this, right? The only games you'd have the power to do this are old emulated N64 games, which already have splitscreen built in.

I think you are both somewhat underestimating the power of the steam deck and probably very much overestimating the type of games people are gonna want to use this for. A game like Minecraft, for example, doesn’t need much processing power, so I think it would be able to pretty easily handle two or more instances of it, but yea if you try and run idk two or more instances of cyberpunk or Diablo or whatever, yea it’s not gonna work.

And my point is that even Minecraft wouldn't work. People need performance mods to get that running at 60FPS at 720p. That's *one* instance of the game. Two would be a slideshow.

Like I said, the bulk of games you'd have the power to play are older games or indie arcade couch-coop games with built in splitscreen. Stuff in general you wouldn't need Nucleus for.

The OP specifically cited Black Ops 2. Which goes back to my point: people's intentions with this are to run games that the Deck can't really run two instances of at adequate performance.

I’ve been able to get two instances of Minecraft running, and I don’t believe I was using any performance mods.

Just because the games YOU want to play require a lot of resources, there's still plenty out there that are useful. You would also be wrong about the performance.

Reddit: I Rented Out A Movie Theatre (Again) and Used my Steam Deck to Play Co-Op games!
By user: Visual_Performer1665

TLDR: Minecraft Legacy4J, Black Ops 2, and Switch emulation for 8 players at a theater.

"Minecraft with a TON of performance mods, ran at a perfect 60fps the entire time, with each instance having 6 chunks to save on memory.

COD BOII with all of the lowest graphical settings, ran at 60fps in all of the instances."
