Pause the game and press:

L, A, Up, Down, R, Up

The passcode box on the screen will change to read: #PWR to indicate that the code is in place. While the game is still paused, press and hold B to get the level select to appear in the password box. With B still being held, press Up or Down to choose a stage, then release B to warp there.

At the title screen, hold R and rotate the D-pad clockwise until 7 splashes of blood appear on the screen. This will allow you to see blood when you shoot someone in the game.
