BB4CPC (shorthand for "Bubble Bobble for CPC") is a retro remake of "Bubble Bobble", Taito's unforgettable 1986 arcade game hit, for the Amstrad CPC 8-bit home computer series. It was developed with the purpose of running on any CPC machine, regardless of RAM size or CRTC model, while staying as faithful to the original game as it could be done in 48 kB of code and data.

BB4CPC was developed by César Nicolás González, "CNGSOFT".
