MARIO BROS. — Atari ST / STE port
By TjLaZer 2026

A port of Nintendo’s 1983 arcade Mario Bros. to the Atari ST and STE. It’s
converted from the original arcade program, so the gameplay, enemies, phases,
bonus rounds and attract mode match the arcade.

Requirements

Any Atari ST, STE or Mega STE with 512K or more (runs on a 520ST)
Colour monitor or TV (low resolution)
The STE uses its 4096-colour palette and smooth scrolling; the plain ST uses
the 512-colour palette

MARIO.ST: bootable floppy image, starts automatically from the AUTO folder
MARIO.PRG: run from desktop or hard disk

Features

The game runs at arcade speed (60 frames per second) on both ST and STE
