Things You'll Need
Instructions
Connect the broadband adapter to your router, then open "Network Connections" on your PC. The new connection should have an "X" next to it because it isn't connected yet. Go to "Properties," then change the IP address and preferred DNS server to "192.168.1.100" and change the subnet mask to "255.255.255.0" as well.
Start PSO I &II on GameCube with the blank memory card inserted. Choose "Online Game" at the start menu, then select "Network Setup." Name this connection "LAN" and choose "Set up manual address." Change the IP address to "192.168.1.32" and the subnet mask to "255.255.255.0" and change the primary DNS server and default gateway to "192.168.1.100" as well.
Click "Next," press "Connect" on the "Start" menu and enter your authentication code from the game box. Create a simple password, then click "Next." On your PC, install PSUL v1.1, then go to "Start," then "Run" and type "psul -s" into the appropriate box. PSO will disconnect, but save your settings to the memory card.
Install Cubesoft's Phoenix on your PC. Connect to the lobby again in PSO on the GameCube, then run Phoenix from the Start menu of the PC. You can load a ROM or ISO to run backup GameCube games or emulated games and they will stream to the GameCube via the broadband adapter.
