Online Multiplayer (Netplay)

Port Forwarding (Host Only)

• If your internet operates through a router (Wi-Fi, etc.), and you wish to Host a netplay session outside your local network, you must configure port forwarding for your chosen port.
• The default port is 5394
• Instructions for specific routers can be found here
• If you are unable to port forward, you can try alternatives such as Tunngle or Hamachi
  
  

Starting a session

• (1) Start Spelunky, then Frozlunky. (Make sure Spelunky is in windowed mode.)

• (2) In Spelunky, enter the main menu (NOT the pause menu!) and set your selection to Achievements

  • 

• If you are host:

  • (3) Click the Host button in the Netplay window. If you wish to have your own camera (i.e. the camera is not focused on Player 1) check the "Enable own camera" checkbox.
  • Give your partner the IP and Port (default 5394), and wait for a connection.
  • Netplay window will tell the ping when connected.

• If you are the client:

  • (3) Enter the host IP and Port (which your Host should give you) into the respective boxes. Click Connect. Check the "Enable own camera" checkbox if you wish to have your own camera.
• (4) Once connected, both players must click back into Spelunky and the Host will be able to control the menus.
• (5) The host, who is Player 1, can then navigate to Play Game and start.
  
  

(Host: Important) Buffer Size

• It is best to minimize Buf as much as possible
• Higher values of Buf will result in more input delay, but less stutter.
• Lower values of Buf will result in less input delay, but more stutter.
• The Host can specify the netplay buffer size by entering a number next to Buf, then clicking Set
• Each increment of Buf is approximately equal to 16 ms of ping.
  • For values of ping < 30 ms, you can probably specify a buffer size of 2, 3, or 4.
  • For values of ping > 30 ms, less than 60 ms, 5, 6, or 7 should be safe.
  • Ideally, this is a value you want to determine through testing, and strike a balance between input lag and game stutter.

Mods

• Mods are additions to Spelunky via Frozlunky.

• Current Mods:

  • All levels are dark

    Forces all levels to be dark

  • Dark levels are possible on hell / ice caves.

    Makes it possible for hell and ice caves to be dark.

  • End Timer is not set to 99 minutes

    By default, Spelunky considers runs faster than 1:30 
    to be invalid, this mod removes the limitation.

  • Display precise timer

    Creates a more precise timer at the bottom left corner of
    the screen (milliseconds thousandths)

  • Hybrid AI Mod

    Combines together enemy AI.
    
    - Adding AI:
        - To add an enemy AI, select an enemy from the drop-down
          and press "Add"
    
    - Removing AI:
        - To remove an enemy AI, select it on the added AI tree
          and press "Remove".
    
    - Piranhas Unaffected Option
        - This option will prevent crashes caused
          by large numbers of piranhas in the Jungle. 
          (useful for Orange Frog, Big Frog, Tank, etc.)

Score Submission

• Score submission is disabled when Frozlunky is enabled on Spelunky.
• To re-enable score submission, Spelunky must be restarted.

Possible Errors

• Failed to initialize Frozlunky, try restarting Spelunky. This error generally means Frozlunky can't find the necessary hooks in the running Spelunky instance. First, try restarting Spelunky and launching Frozlunky again. If you continue getting this error message, try reinstalling your copy of Spelunky.
• Spelunky is not running, please start it and then launch Frozlunky. Frozlunky depends on Spelunky being active, please start Spelunky and then launch Frozlunky!
