Game Boy Color
The Game Boy Color is the fourth model to the Game Boy and, in some ways, the handheld counterpart of the Nintendo 64. It is similar to its predecessors, the most notable differences being that it is lighter, it is capable of displaying multiple colors, and the processing power is twice as fast. It is the final handheld to feature 8-bit graphics.
Some games made for the original Game Boy display more colors if played on a Game Boy Color. Other games were made exclusively for the Game Boy Color. The older versions could not play these, but the Game Boy Advance, the Game Boy Advance SP, and the Game Boy Player could.

Mobile Adapter GB
Only available in Japan, the Mobile Adapter GB allowed certain games to connect to some Japanese mobile phones.

There is an infrared LED, indicated by the black rectangle on top of the unit, that a Game Boy Color can use. This was the primary method in which Mystery Gift worked in the Generation II Pokémon games, but Super Mario Bros. Deluxe can make use of this feature by sending high scores and other data to other copies. This feature is exclusive to the Game Boy Color and is not present in later Game Boy devices.
The Game Boy Color will display a unique hardware-coded palette of colors for some titles using an internal list of original Game Boy games. Two such instances are Super Mario Land and Super Mario Land 2: 6 Golden Coins.
