Aside from PCs, the black and white Game Boy with its ghosting “spinach” screen was the most popular and successful gaming platform of all time. It maintained its market supremacy through a gauntlet of would-be competitors, such as the Game Gear, Lynx, and Neo Geo Pocket. The stripped-down nature of the hardware and its games, coupled with low development costs, meant that some real classics and neat curiosities were allowed to emerge that would have been rejected by their publishers as too simple or experimental for console release. Like the NES, the Game Boy has an absolutely massive library of commercial games, owing to its extensive lifespan as well as its popularity. Game Boy cartridges will play on the Gamecube's Game Boy Player, and Game Boy Advance models that aren't the micro.
