You must do this:
- Choose 'SNK Football Championship'
- Win 3 matches. (*)
- When you are going to play level 4, you'll see this message: 'Here comes a challenger'. The name of that team is 'SNK Superstars'.
(*) It appears if you are unbeaten (for example: 4-0, 2-0, 1-0).
If you aren't, that team can appear if you humillate your rivals (for example: 5-0, 5-0, 5-1).
