[big]Remakes[/big]

__Super Mario All-Stars__ Framerate: 39375000/655171 ~= 60.09881387708959 (SNES NTSC), ~59.824 (Wii VC NTSC), ~59.94 (Wii U NTSC), ? (SNES PAL), ? (Wii VC PAL), ? (Wii U VC PAL) Super Mario Bros. has been remade for the SNES and bundled with other games in the series. The graphics have been updated and some glitches are fixed. There is also a version which contains Super Mario World too.

Differences from the NES version The hitboxes are less forgiving, especially notable with the Piranha Plants. Luigi still accelerates less quickly than Mario, but the difference is less. World 9 does not loop anymore and you retain your life count instead of having it set to 1. You go to World A after finishing 9-4 instead. The bonus world A-D come directly after 8-4 (or world 9-4, if you play without warps) instead of having to beat the game 8 times and having to use a code on the title screen to play them as in the original. You start with 5 instead of 3 lives. Losing all lives makes you restart from the start of the level instead of the start of the world. As big Mario/Luigi, you can get your head stuck in the ceiling when breaking a brick. This brings you to a stop in the air and you lose your speed. There are new level transitions screen, which you have to skip (or wait out and lose time). There is a sound clue in maze levels to tell you, if you are on the right path or not. There are no checkpoints in the bonus worlds. The Hammer Brothers in the bonus worlds now always charge at you. The Bowsers in the bonus worlds now throw hammers. In the bonus worlds, the enemies move quickly if you beat 8-4 without using warps. If you beat 8-4 using warps, the enemies will move at normal speed. If you save and quit and return to your game, enemies will move quickly. You can finish the ending sequence of a level faster by touching the flagpole backwards (facing left). There is one less seaweed blocking your path in 3-2. The Wrong Warp in 5-2 is no longer possible. Despawning happens way less frequently.

__Super Mario Bros. Deluxe__ Framerate: ~61.17045102596282958984 (SGB1), ~59.7275005696058 (GB/GBC/GBA/SGB2/GBP) This is a remake for the GameBoy Color with both the prequel and this game. You need to beat the first game to unlock Lost Levels. It has a different engine and many glitches fixed. The graphics resemble the original Super Mario Bros. more and new elements such as the wind have been removed.
