You remember the ol' Konami Code, right? In case you've forgotten, it's:

Up, Up, Down, Down, Left, Right, Left, Right, B, A

And it's used in lots of Konami-branded games.

Like the arcade game compilation Konami Collector's Series: Arcade Advanced, which has five old-school arcade games for you to test your mettle in. Complete with original graphics and sound!

But, go to the title screen of your favorite game and put in The Code and you'll hear a sound

And when you start the game, behold!

Better Graphics for you! And this works for all the games in the compilation.

Except for Rush 'n Attack, the graphics stay the same, but you get more lives to play with

Which is probably more useful in that game anyway.
