If you use multiple keyboards/mice after the instaces finish setting up 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. If you are going to use controllers you need to have Forge and the Controllable mod installed, assign a different gamepad per instance in the Controllable mod Minecraft menu and disable it for kb instances.";
