Wily Again, Now in Full Color Mega Man III on Game Boy is a curious beast: it blends bosses from both Mega Man 2 and Mega Man 3 on NES into a single portable adventure, with its own unique stages and story connecting them. It's classic Blue Bomber action in a compact package — and like all the Game Boy Mega Man entries, it shipped entirely in monochrome despite deserving so much more. Custom cartridge, plug and play. Compatible: GBC, GBA, GBA SP.
