Note, this is a copy/paste from Pure ZC:
This is a tutorial to show you how to get a working connection between 2-4 players on any GBA game.
The game I'm going to choose to play with some friends is TLoZ: Four Swords.
What you'll need:
Windows Users
� VBA Netplay Emulator
� Hamachi Client
� The game you want to play.First, download and install Hamachi for the OS you have and install.
Once its installed, press the Power Button which should prompt you for a user name.
Once you have your username, press the "Create or Join Networks", join this:
Network: PureZC
Passowrd: purezcOnce you have joined, install VBA Link.
Be sure to set your controls, and make a save state at the "Press Start" screen for Four Swords.Once you have made your characters name and have your emulator settings at a ready-to-play state, we can begin.
Have your emulator loaded with Four Swords at the Start Screen and press "Options> Link> Wireless Adaptor".
Now press Ctrl+M, it should bring you to Link Options.
[QUOTE]Link timeout: 2000
Network: Checked (Not Single Computer)
Advanced: Faster
Port Number: 5738
Now select the "Server" tab, you were origionally in the "General" tab.
Server is for hosting the game, others will join you through "Client".
Once you join the PureZC Hamachi server, you'll automatically be given a Hamachi IP, use the Client feature to join your friend who's hosting the games IP.
If their are any problems, reply to this post.
Feel free to play any games you want to play, it doesn't have to be just four swords.
Also, do not ask for rom sites or rom links.[/QUOTE]
