Game Boy Color infrared communications
The Game Boy Color contains new infrared ports, allowing for infrared communications in compatible games, between other Game Boy Colors or devices, including Pokémon Pikachu 2 GS, infrared light sources in general, or third-party devices, such as television remotes, the Pocket Sakura, or the Full Changer used in Zok Zok Heroes. This was previously not included in the Game Boy/Game Boy Pocket, although it was possible with special Game Paks on a regular Game Boy (such as the Japanese version of Pokémon Trading Card Game; utilising Hudson Soft's GB Kiss feature; see non-Color Game Boy infrared communications).
The infrared feature allows players to send and receive serial data; a feature similar to the Link Cable wirelessly. However, Nintendo officially discontinued infrared communications with the release of the Game Boy Advance, which removed the infrared ports. Before wireless communications became mainstream, the popular Pokémon series also primarily used the Link Cable for trading and battling (once the only means), although the ability to trade and battle wirelessly was introduced later with the Mobile System GB (online using Japanese mobile phones; unpopular), Game Boy Advance Wireless Adapter, and Nintendo DS wireless communications; including infrared trading in Pokémon Black and White Versions.
The infrared communications were emulated in Nintendo's official Virtual Console versions of Pokémon Gold and Silver Versions, Pokémon Crystal Version using the Wireless Communications of two Nintendo 3DS systems. However, the communications were disabled for Pokémon Trading Card Game, Super Mario Bros. Deluxe.
A few games such as Chee-Chai Alien and Zok Zok Heroes are locked out on Game Boy Advance (without modifications), as they require the infrared feature.

Third-party peripherals
- Full Changer (packaged with Zok Zok Heroes; it is responsible for transmitting the player's moves to the game; registered as a "Cosmic Character", and corresponds with a hero transformation)
- Spectrum Communicator (packaged with Chee-Chai Alien; it is optional, attaches to the Game Boy Color, and is advertised as enhancing the infrared reception in some way)
- TV Adaptor (cancelled; this device would read barcodes from a television screen and convert it into infrared data to be used with the infrared port. It was discovered that there was cut support for it in Sakura Taisen GB: Geki Hanagumi Nyuutai! after data-mining the game, and through patent JP,2001-239060,A. Also, it is alluded to as an upcoming feature in the manual of Sakura Taisen for Dreamcast); "In One Long Day mode, you'll occasionally find a 'TV mark' displayed on the screen. Remember where these marks appear, something good might happen with them later.")
Technical information
It is not recommended to use the infrared feature for too long as it will drain the battery.
In the Dan Docs (an unofficial reverse engineering document); Shonumi defines four communication types:
- "1-Player Init" games (in the context of two Game Boy Colors), such as Pokémon Gold and Silver describes games which only require one Game Boy Color to initiate infrared communications, but will wait for both Game Boy Colors. The initiating game will send the pulse for the other to receive it (similar to the "master" and "slave" relationship for devices such as the Link Cable). 1-Player Init applies to most infrared compatible games.
- "2-Player Init" games will wait for both Game Boy Colors to initiate at about the same time. This applies to games such as Pokémon Pinball (for score exchange) and Pokémon Trading Card Game (for Card Pop).
- "Active Object Init", such as Pokémon Gold and Silver with Pokémon Pikachu 2 involve communications between a Game Boy Color and a non-Game Boy Color device, with the non-Game Boy Color device being capable of both sending and receiving infrared signals.
- "Inactive Object Init", such as Chee-Chai Alien involve communications between a Game Boy Color and a non-Game Boy Color source (doesn't need to be a device and can even be something like a household lamp), which is capable of sending infrared signals but not receiving them. Another example is the Full Changer for Zok Zok Heroes also falls under this category, as it can transmit data but not receive it.
Infrared communication requires the correct timing, but there is no specific way to program this; with some games relying on Game Boy Color hardware timers or hardcounted values for counting cycles. However, four particular games (part of the 2-Player Init category) by Hudson Soft share similar infrared protocols for the initial handshake; Pokémon Trading Card Game, Pokémon Card GB 2: GR-Dan Sanjou, as well as Bomberman Max: Red Challenger and Blue Champion.
The Game Boy Color uses the MMIO hardware register at FF56, known as the RP register. Certain bits are both read/write enabled, while others are read-only.
Bit 0: Write 1 to turn IR light ON, or 0 to turn it OFF (R/W) Bit 1: If 0, receiving a signal. If 1, the game considers no signal. This will also be 1 if the Game Boy Color has continually been exposed to the signal for too long, referred to as the "signal fade". The signal fade time also has an inverse relationship between the distance between the Game Boy Color and infrared signal; so fade time is longer for closer distances. (R) Bits 2-5: Unused Bits 6-7: If 0, disable reading signal. If 3 (binary: 11), enable reading it (R/W)
