Handler notes

Requires version 1.29 or earlier versions of the game (the ones before battle.net launcher) .

Watch the Video guide, or read below.

PCGamingWiki page.

Download and extract the latest version of Nucleus Co-op, and run it as administrator. Download the Game Handler through Nucleus Co-op, and assign the keyboards and mice how you see fit (if you're only 2 players I recommend vertical split).

Warcraft III: Reign of Chaos classic is also playable if you select yes in the Nucleus UI option to launch it. Make sure you only have one Warcraft III .js file in Nucleus handlers folder.

Press the END key to lock the input after the instances have finished setting up so that all instances have their own working cursor. You need to left click each mouse to make the emulated cursors appear after locking the input. Press the END key again to unlock the input when you finish playing. You can also use CTRL+Q to close Nucleus and all its instances when the input is unlocked.

To start a split-screen game, click "Local Area Network" on all instances. Then "Create Game" on one of the instances, choose the map you want to play and create game. Now the game should show up on the other instances, if it doesn't simply go back to main menu (click "cancel") and go back in. Join the game, depending on the map, you can choose game rules and teams. Once all instances have joined, start the game, and let the fun begin! :D

If you get a firewall popup asking for permission to communicate on the network, click END and CTRL+T , accept the prompt, then click END and CTRL+T again. If your mouse gets locked to a small part of the screen, simply left-click and it should work fine. If not click CTRL+Q to exit. Then relaunch through Nucleus, and it should work just fine.
