Things You'll Need
Instructions
Plug the wireless receiver into the USB port of the PlayStation 2 console.
Plug the microphone into the second USB port of the PS2. It does not matter which port is used for the receiver or microphone.
Plug a PS2 controller into the first controller port. This controller is used by the player using the microphone to navigate the game menus. The guitar, bass and drum players use their instrument controllers.
Turn on the console with the "Guitar Hero: World Tour" disc inserted.
Press any game mode from the main menu, except for Solo Career or Battle modes. Those two modes do not allow four players at the same time. This step can be performed by any player.
Press the green button on the three other controllers in the "Band Select" screen. The drum and vocal player automatically get assigned to the appropriate instrument in the band. Players using a guitar controller can choose between the guitar or bass role in the band because both use the same controller. There must be one guitar and one bass player. If one player chooses to play the guitar, the second player is automatically assigned the bass.
Pick a song from the song list that appears after the "Band Select" screen to start playing.
