Super Mario Advance 4: Super Mario Bros. 3

Super Mario Advance 4: Super Mario Bros. 3 is a faithful GBA remaster of the NES classic, sending Mario and Luigi across eight worlds of the Mushroom Kingdom to reclaim the kings turned into animals by the Koopalings and ultimately face Bowser to rescue Princess Toadstool, all built around the original's overworld map structure that let players choose paths and skip levels.

The GBA version adds enhanced visuals and audio over the NES original, plus e-Reader card support that could unlock bonus levels and rare power-ups by scanning special cards through a Game Boy Advance e-Reader peripheral — content that's preserved in ROM dumps even though the physical e-Reader hardware is long out of production. Classic power-ups like the Super Leaf's Raccoon Mario, the Frog Suit for underwater levels, and the Tanooki Suit's statue form are all present, alongside the series-defining airship levels.
