The classic Konami Code works in this game! Instead of using it at the game intro, however, you'll want to use it after pausing your game. Using it will give you the best version of certain weapons. In case you've forgotten the Konami Code (or never knew it), it's the following: Up, Up, Down, Down, Left, Right, Left, Right, B, A, Start.

Here's a step-by-step way to get 99 lives in the game.

• 1.) - On the first stage, get to the stage's mini-boss, die, and lose one continue. This will start you back off in the middle of the stage.
• 2.) - Perform the "Konami Code" here on IGN Cheats.
• 3.) - Get back to the mini-boss and kill him. Then, work your way to the stage's final boss.
• 4.) - Kill the sniper enemy above the boss, and shoot the red center of the boss 49 times.
• 5.) - From here, die until you have "00" lives left.
• 6.) - Stand in front of the red center of the boss, shoot at it (for the 50th hit) and press start immediately after (practically simultaneously).
• 7.) - Perform the "Konami Code" one more time.

If this is done properly, you should now have 99 lives!
