Mario Bros. for the Atari 7800, released in July 1988, is a vibrant port of Nintendo’s 1983 arcade classic, developed by Atari Corporation under license. Preceding Super Mario Bros., it features Mario and Luigi as plumbers battling pests (Shellcreepers, Sidesteppers, Fighterflies) in a sewer’s single-screen stages. With ~3 million Atari 7800 consoles sold, this port shines for its co-op gameplay, praised on X in 2025 for its nostalgic charm and Atari 7800’s MARIA chip visuals ().
