Unlock 30 Lives at Start:
This code is done at the title screen. Put in a code ‘similar’ to the old Konami Code with some slight differences. Enter Up, Up, Down, Down, Left, Right, Left, Right, Click Left Stick, Click Right Stick. This will get you 30 extra lives at the start.
Contra Stage 1 Music:
While the loading screen is loading up, enter the classic Konami Code Up, Up, Down, Down, Left, Right, Left, Right, B, A. This will queue a “Let’s Rock!” voice and it means the code worked. You need to put in the code before you get the prompt to start the game.
