Bubble Bobble 2 cheat codes (for NES)

[final kaoss]

Different diamond colors

To get the different diamond colors, the "colorized" enemies must fall in certain parts of the screen. For example: an enemy that's item falls on the extreme right of the screen has a good chance of giving you a purple diamond, and one on the right should give you red. Use this information to your advantage!

Character trick

The characters in world 8 look strange, but they appear throughout the game. I noticed that when you "colorized" or killed an enemy in one of the 7 main worlds, the little blob that spins (before it turns into an item) is one of these creatures. (To get a good look, pause the game when you kill an enemy.)

Level 70 and 80 bosses

Face the wall and jump while shooting for the best attack. When fighting the three ghosts, kill one of them and wait until the red one is on your half of the screen before killing another. If you do this right, using the wall strategy, the final giant red boss won't have a chance to do anything to you before it dies!

Level select

When the Title Screen appears and the message "Press Start" is flashing, press Left, B, Right, Up, Down, Left, Right, B. The message "World 1" will appear, and you can change the Level by pressing A. You will not be able to get the best ending.

Gems tip

Collecting all of the gems in the correct order of color (from left to right on the gem counter - Red, Orange, Yellow, Green, Light Blue, Dark Blue, and Mauve) not only awards you the life and Bonus Gem, it also grants you access to a magical secret room. When you reach the end of the level, a silver door appears. You don't have to fight the Boss.

Skip from Level 5 to 7

On the fifth island you'll find a box in the secret room which you should collect. There's also a gate with a '7' on it, leading to Island 7.
