This is a list of cancelled Game Boy Color video games. The Game Boy Color (GBC) is a handheld video game console released by Nintendo in 1998. The color-screened successor to the monochrome Game Boy, first released in 1989, the GBC's time on store shelves was comparably short, being succeeded by the Game Boy Advance (GBA) in 2001. During this time, several games being developed for the system were cancelled for reasons such as technical limitations, financial difficulties, and the forthcoming release of the GBA, with a number of games being moved to that system instead. Many of these games were not known about in detail or in any capacity until 2020, when ROM images of several game prototypes were leaked onto the internet as part of a larger Nintendo data leak.[1][2] This list documents all known games that were confirmed to be announced or in development for the Game Boy Color at some point, but did not end up being released for it in any capacity.
