Super Mario Bros

Super Mario Bros is the 1985 NES cartridge that turned side-scrolling platformers into a genre — 32 levels across 8 worlds, four stages each, with a fire-breathing Bowser (or a Hammer Bro doppelganger) waiting at the end of every castle. It's also the game that taught a generation the shape of a warp pipe meant "there's more here if you look."

The three secret warp zones in World 1-2, 4-2, and — for the truly precise — the famous Minus World glitch accessible from 1-2's warp room, turned speedrunning into a thing before speedrunning had a name. This ROM is the PRG1 revision, the one that fixed the original PRG0 build's audio bug where stomping certain enemies could cut out the background music.
