HuC-3 Mapper Curiosity#
This game (data) uses Hudson Soft's HuC-3 mapper. According to this post by endrift on Gameboy Development Forum, HuC-3 is an extension to HuC-1, based on MBC5 with an IR sensor (often branded as "GB Kiss"), a predecessor to Nintendo's built-in infrared capabilities for Game Boy Color, using sensors/transmitters from the cartridge rather than the hardware.
However, also based on Shonumi's research for the Dan Docs, this choice may not have been necessary - Pocket Family GB 2 is a Game Boy Color-only game, and does not use GB Kiss. More research in general is needed for this game and to determine whether it was always meant for Game Boy Color.
