On the character selection screen, type in "WHAT A GREAT LOAD OF B*******S" (NOTE: It might be "WHAT A GREAT LOAD OF BULLOCKS"). Another magazine says type in "WHAT A LARGE SET OF BOLLOCKS". Be creative with the asterisks (think about another term for cow manure) and the border will change color. Use the main keyboard keys: '1' - '5' and press 'Fire' to skip to the corresponding level.
