NOW the most important part, the online play. By now you should have set up your video settings, your input, and have the ROMS in your ROM list. Now let’s head into the battlefield. From the emulator main menu bar, go to Utilities-> SupraClient (NetPlay). This will bring up the online client where you connect to the server where you make your online game. If everything is ok then you should see this:

This is the main client window, here you enter your info like username, connection type(leave good unless playing Mario Kart where you should use LAN type). In the highlighted area, enter a username by which you will be recognized when you join the server. The rest of the stuff leave alone for now.
Next, click the “Servers” button to get to the server list, and right-click where it says, then hit refresh. pic here
After this you will get a list of the Kaillera servers available. The one where almost all the N64 emulation goes on and where you will almost always find GoldenEye players is in the server “Emularena Grounds – {Unit X}” server (IP: 69.90.34.14:27888). To login to this server, just copy that IP into the empty box above username, then click “Login”. Now the server will appear in your “Recent List” tab in the servers list next time you use it.
After you connect to the server, you should see something like this.

Heres is where all the fun takes place. The host of the game being played will create the game room here and other players will join him here. Notice the different emulators and games being played, you cannot play with them since you are not on that emulator and don’t worry, all the Project64k 0.13 players usually play is Super Smash Bros. which can be played in Mupen64++ 0.1.3.12 as well.
