Mario on Game Boy is a puzzle game that stood the test of time — drop colored capsules, match three in a row, eliminate the viruses. Simple to learn, endlessly replayable, and utterly merciless at higher speeds. The only thing it was missing? Color, and a few more doctors. Mario DX by marc_max (v2.1) solves both problems at once. This GBC hack doesn't just add full color to every capsule, virus, and Custom cartridge, plug and play. Compatible: GBC, GBA, GBA SP.
