Nucles Co-Op is a tool for Windows that allows split-screen play on many games that do not initially support it. Its purspose is to make it as easy as possible for the average user to play games locally.

Support its development by helping on my Patreon! https://www.patreon.com/distro Subscribe to our subreddit: https://www.reddit.com/r/nucleuscoop/

Currently Supported Games:

• Borderlands 1
• Borderlands 2
• Borderlands: The Pre Sequel
• Don't Starve Together
• Left 4 Dead 2

Working but not with all features:

• Borderlands ALPHA 8: Everything works if you're using gamepads, but not with a keyboard + mouse player

So close but not there yet:

• Saints Row 3 Working: All instances open correctly using SmartSteamEmu, can control all instances freely Issue: Can't find the game on LAN. If from the Shift + Tab menu, the game says the session is no longer available.

Starting from Alpha 4, all games use a generic handler that can handle pretty much all situations. To add a new game, you can just create a new *.js file on the games folder, and describe what your game needs to run. Now, what the GenericHandler actually does?

When the user hits play:

• If the game needs modifications to the save files, we backup them so when the splitscreen session ends we can return all the configurations back to normal.
• The app symlinks the entire game folder to the Data folder, so we can launch each instance of the game with custom DLLs.
• Runs the JavaScript engine, so any custom code that needs to be executed by player ID runs
• We copy a custom xinput dll specific for each gamepad: Each xinput passthroughs a specific gamepad input to the 1st gamepad (xinput1 just passtroughs, xinput2 passes to 2, i.e).
• If needed, we extract SmartSteamEmu and start the game using it.
• Now we keep track of the processes, looking for the launcher and the actual game window, so we can position it correctly on the screen.

Next on the List:

• Left 4 Dead 1
• Portal 2
• Call of Duty: Black Ops
• Call of Duty: Modern Warfare 2
• Saints Row 3
• Saints Row 4
• Team Fortress 2 (support for 64 players on 1 machine FTW)
• Unlimited Power mode (multiple keyboards + mouses + gamepads)

Games I want to add but I don't own:

• Call of Duty: World At War
• Call of Duty: Modern Warfare 3

A ton of games will be supported thank for the godsend tool called SmartSteamEmu, developed by syahmixp, grabbed from http://cs.rin.ru/forum/viewtopic.php?f=10&t=62935 Awesome application that emulates Steam and even enables LAN connections, so we can play everything easily!

If you want to truly code, here follows a somewhat summup of what you need to begin developing:

For the application: - Visual Studio 2015 or 2017 (Community works fine)

For the games's Javascript files - Visual Studio Code - Node.js (not yet) - ProcessExplorer
