  3. Take a seat

    Each player presses a button on their own controller to join and takes a spot on the screen. Pick a layout that fits your players.

    Playing with several keyboards and mice? Press End once everything is in place to give each window its own cursor.

  4. Launch and connect

    Press Launch: Nucleus opens one copy of Castlevania: Harmony of Despair per player and lays the windows out on your screen. Then link them in game, usually one player hosts a LAN or online session and the others join it. The handler notes say how.

Handler notes

  • Requires the x64 Castlevania: Harmony of Despair Unity PC Port, get it from their discord server or from here. Kudos to the devs for their great work.

  • Split-screen setup.

  • When the game launcher opens quickly tick windowed and click play for the windows to resize correctly.

  • If your gamepads do not restrict correctly make sure the xinput indexes option in Nucleus settings-players tab is unchecked, you will have to maintain a button pressed in your gamepads to make them show in the Nucleus UI.

  • If you use keyboards and mice after all the instances have launched, resized and positioned correctly, press the END key once to lock the input for all instances to have their own 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.

  • Set the game to English in the option before the last one if it is in Japanese.

  • Create a multiplay team game in one instance and join in the others, select a different character per instance. If you have issues connecting the instances try what it is shown in this video, also try using no in-game names and a different color per player.

  • Read the FAQ if you have any further questions and want to know more about Nucleus Co-op.

  • Known issues: Xbox One/Series gamepads could have issues with background input/focus because of this. You can use the app reWASD to covert them to xbox 360 gamepads or follow this guide.

  • Handler by Talos91. Please support the Nucleus Co-op team if you like my Nucleus handler work.

  • UI fix in ultra wide and vertical resolutions by czarman from the WSGF discord.
