Colour-emphasis games

The following is a list of games which make use of PPU register $2001's colour emphasis bits (D7 to D5):

Commercial

• Bubble Bobble for the Famicom Disk System uses red emphasis to tint the screen throughout the game, which is absent in the cartridge releases.
• The Fantastic Adventures of Dizzy uses it in the beginning when the scroll is unfurled.
• Final Fantasy and Final Fantasy II rapidly sets and clears all 3 emphasis bits to flash the screen when going into a battle screen, also rotates colors when entering the status screen.
• Super Game's Aladdin uses red emphasis to tint the screen during gameplay, and all 3 emphasis bits to dim when paused. The official version of Aladdin, released only in Europe, also uses the emphasis bits to tint the screen green during gameplay (as the PAL console flips the red and green emphasis bits), but does not dim the screen when paused.

The following games set all 3 emphasis bits at once to dim the screen:

• Cliffhanger
• Cybernoid - The Fighting Machine on the top part of the difficulty select and better luck next time screens. Also uses red emphasis when the screen changes in-game.
• Dragon's Lair
• Felix the Cat
• Fun House for fading out
• The Immortal
• Indiana Jones and the Last Crusade (Taito), story scenes and some action scenes.
• James Bond Jr
• The Jungle Book
• Just Breed
• Lagrange Point uses colour emphasis, in some frames combined with grayscale bit to do a very cheap fade-out effect when switching to and from the menu on the playfield, and also when entering into battle
• Legend of Prince Valiant, The (E) uses full emphasis on the title screen, green emphasis for gameplay and red emphasis for status bar
• Lethal Weapon
• The Lion King (E)
