The Smash TV games are pretty tough. Mostly because you go up against thousands of enemies and your guy can only take one hit before he dies. So unless you spend lots of time mastering this game (or lots of quarters if you're playing the arcade version) you're never going to see the advanced levels.

Unless...

You go to the screen where you select 1 or 2 players

And press Right, Right, Up, Down, R, L. You should hear a voice yell, "Bingo!". Choose the amount of players, hit Start and

You can start pretty well wherever you want!

As an added bonus, if you hold Select before you enter a room, and keep holding it, the enemies won't even appear.

So you can pretty much explore the studios to your heart's content.

Double bonus!
