Super Mario Bros.:The Lost Levels/Version Differences

Super Mario Bros.:The Lost Levels was initially released for the Famicom Disk System. Due to its similiarity with Super Mario Bros. and high difficulty it was not released outside Japan in its original form until the Wii Virtual Console release, but a remake of it made it into the SNES Super Mario All-Stars game collection.
The framerate of the Famicom is 39375000/655171 ~= 60.09881387708959.

Differences from the NES version

• 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 andh aving 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 due to the slightly changed physics of the characters. 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.
• The springs in world B are less powerful.
• It does not happen anymore in C-2 that 2 Bullet Bills fire in rap succession.
• You can finish the ending sequence of a level 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.
