1 From the main menu select "Multiplayer"
2 Chose your P1 character
3 Now hold the button and select "Switch User"
4 Select a P2/P3/P4 account players - personally I just made 3 Guest Players (Guest1/Guest2/Guest3)
5 Once you selected a guest make sure you press to join and chose any character.
6 After successfully making all 4 slots playable human players, set the "Rounds" to 1 to make the trophy unlock faster with just 1 win.
7 Select any Stage Map but do note that sometimes it might be a guest character who can select the map stage, so switch to the guest controlled player to select the map stage.
8 Switch back to your main trophy profile account and win the game.
