Netplay Support

Netplay does not currently work, and may not return in a future version. If you want to see it return, please upvote an existing issue or file a new issue at https://github.com/snes9xgit/snes9x/issues so we know that players are using it.

Netplay support allows up to five players to sit in front of different computers and simultaneously play the same game, or just watch someone else play a game. All the computers have to be connected to a network that allows TCP/IP traffic to flow between them; this includes a local Ethernet-style network, a direct-cable connection, or, if you're lucky and have short ping times, the Internet.

Snes9x netplay inevitably synchronizes all the computers at the sacrifice of the speed of input response. Note that netplay is not compatible between platforms - You can't play via network with Windows users.

How to Netplay

The player with the fastest Mac should act as the server. The others are clients. Server should open the port 6096/TCP.
Here is the workflow to netplay with up to five players.

• Server	If you guys want to play with Multi Player 5, choose 'Multi Tap' in 'Input Device' in 'Emulation' menu. (Clients don't need to select it.)
  Server	Open the ROM image. Pause the game and exit from the emulation loop.
  Server	Choose 'Server...' in 'Netplay' menu. The clients list appears. The first client is yourself.
  Client	Choose 'Client...' in 'Netplay' menu.
  Client	Input server's IP address and your name. Press 'Connect' button.
  Server	The clients appear in the clients list with 'Connecting' status.
  Client	A ROM load dialog appears. Open the same ROM image as server's.
  Server	Wait until all clients become 'Ready'. Press 'Play' button.
  Client	The players list dialog appears. Press 'OK' button.
  Client	Netplay starts.
  Server	The game is reset and netplay starts.
  Server	Adjust the timing by '2P-L' and '2P-R' button. If 'Show Onscreen Information' is active in 'Preferences' dialog, a value appears in both the server's and client's game screen. Increasing this value will smooth the frame rate, but also delay the input response.
  Server, Client	All functions (screenshot, etc.) are unusable.
  Client	Clients cannot stop netplay by themselves.
  Server	Netplay stops when server pauses the game and exits from the emulation loop.
  Server	SRAM file may be overwritten by this play.
  Client	SRAM file won't be overwritten by this play.
