This game has a hidden level select.
A licensed port of Battletoads in Battlemaniacs with an interesting backstory which eventually led the game to be released only in Brazil (and in an unfinished state, at that).
In the short period before the opening text appears, press Up, Down, Up, Down, Left, Right and listen for a sound. Start the game for the Level Select.
