Game Rerun review
Overview
Nintendo dates the original Famicom release to September 13, 1985 and identifies it as the beginning of the Super Mario series. The version running on this page shows the English Super Mario Bros. title screen while the player labels the platform Famicom, so this guide uses NES/Famicom without claiming a specific regional ROM revision.
Each course asks Mario to move through platforms, pipes, enemies, and hazards before reaching the goal pole, while each world's castle ends with a boss encounter. Small Mario loses a life after one hit, a fall, or running out of time, so preserving a power-up is often more useful than chasing every coin.
A Super Mushroom changes small Mario into Super Mario, a Fire Flower gives Super Mario fireballs, and a Starman grants brief invincibility. One hundred coins award an extra life, but stage position and time still determine whether a risky pickup is worth taking.
Cheat Codes
NES/Famicom version: Continue after Game Over: After losing all lives, wait for the title screen. Hold A and press Start to resume at the first course of the world where the Game Over occurred.
Controls
- W / A / S / D
- The player maps these keys to the D-Pad; D was verified moving Mario right. The original D-Pad also handles crouching and pipe entry.
- J (emulated B)
- The player maps J to B; in the original controls, hold B to run or press it as Fire Mario to throw a fireball.
- K (emulated A)
- The player maps K to A; in the original controls, A jumps and swims.
- Shift (Select)
- The player displays Shift as Select for title-menu navigation.
- Enter (Start)
- Start the selected game; Enter was verified entering World 1-1.
Before you play
- Use a short walk for narrow platforms and hold the B mapping before longer jumps. Running adds distance but also leaves less time to correct the landing.
- Treat the first Super Mushroom as protection, not just a way to break bricks. Keeping Super Mario through a crowded section creates room for one mistake and makes a later Fire Flower available.
- Before kicking a Koopa shell, check the full lane in both directions. A rebounding shell can clear enemies, but it can also return while Mario is committed to another jump.
- At moving platforms and Fire Bars, wait for a readable cycle before jumping. The course timer matters, but one safe cycle usually costs less than losing a life and restarting the area.
Known limitations
- The player labels this release Famicom but displays the English title screen; the exact regional ROM revision is not identified on the page.
