未使用的对象#
可攀爬物体#
马里奥可以像藤蔓一样爬上或爬下的物体。 当你爬上去时它会发出“嗡嗡”的声音，就好像马里奥不断地用头撞什么东西一样。 它仍然可以通过关卡编辑器放置在游戏中。 虽然它看起来像一个棕色的旗杆球，但实际上 16×16 使用的 metatile 对该对象是唯一的。

未使用的火焰类型条#
敌人对象 1E 是一个短的火条，逆时针快速旋转。 但是，这种类型从未在任何有效关卡中使用过； 它的顺时针方向 1C 仅在世界 5-4 中使用。
这种火焰棒类型也存在于 Game Boy Color 重制版。
不同于无效的敌人（例如故障火栏 20, 21, 和 22）， 此类型在设置表中具有有效条目：
FirebarSpinSpdData:
.db $28, $38, $28, $38, $28
FirebarSpinDirData:
.db $00, $00, $10, $10, $00
这个设置以这种顺序保存: 顺时针 (1B), 加速顺时针 (1C), 逆时针 (1D), 加速逆时针 (1E), 以及 长火焰棒 (1F). 这种火焰棒 (1E) 还有着更快的版本 ($38) 和逆时针旋转 ($10) 。

未使用的计时器设置#
The upper 2 bits of the first level header setting byte determines the starting timer.
Value |
Bits |
Starting Timer |
|---|---|---|
0 |
00xxxxxx |
000 |
1 |
01xxxxxx |
400 |
2 |
10xxxxxx |
300 |
3 |
11xxxxxx |
200 |
The timer starts at 200 if this setting is set to 3 (11xxxxxx), though no valid level actually uses it.
Likewise, the timer starts at 000 (causes instant death on normal levels) if this setting is set to 0 (00xxxxxx). While this setting is used by intros (such as the beginning of World 1-2), the game doesn't actually use the setting, since it completely disables the timer in these levels.
未使用的刺球行为#
The Spiny eggs are thrown by Lakitu in a simple straight-down way, with no horizontal movement whatsoever. However, this is not the intended behavior, and is actually the result of a bug! The eggs are supposed to be thrown out relative to the player's speed, Lakitu's speed, the player's position, and a pseudo-random value, as well as bounce off of any blocks or walls that they hit on the way down. This behavior is left unchanged in the Japanese Super Mario Bros. 2, so the same fixes can be applied.
The following patch will fix the bug:

This patch is intended for the US version of the game. The Bugs page has more information on the nature of this bug.
In Super Mario Maker this behavior has been restored and the Spiny eggs are thrown as though this patch is applied.

未使用的管道行为#
The L-shaped pipes used in the intro leading to underground and underwater levels can be entered from the top like a regular pipe. However, it is impossible to experience that behavior during regular gameplay, since Mario automatically enters the side of the pipe, and as such this behavior goes unused.
An L-shaped pipe appears in World 9-3 of the Japanese Super Mario Bros. 2, and it is possible to enter this pipe from the top.
奇特的东西#
未使用变量#
内存地址 03F0 用于跟踪砖块击中的数量，虽然从未有程序读取存储于此的值。
Unused Pointer#
Map 01 (Worlds 2-2 and 7-2) has a third level pointer for World 3, which leads to the same place as the normal World 2 and 7 level pointers.
Duplicated Scroll Stop Object#
There are two identical scroll stop objects: 46 and 47. Only the latter is used by the game's valid levels.
已移除的图块#
The bricks and Bowser's bridge may have each used four unique tiles at some point in development, judging by the arrangement of existing tiles in the CHR data. The second and fourth tiles in each highlighted group are pieces of the block behind the title logo.
Piranha Plant's stem animation#
The Piranha Plants' heads have a two frame animation. Interestingly, this also applies to the stem, however the two graphics used to "animate" it are completely identical, resulting in the stem being completely stationary. It should be noted that the Piranha Plant in All Night Nippon Super Mario Bros. (Or Japanese DJ Tamori, to be exact) does use this bottom half as part of the visible animation.
Above-Ground Bloopers#
Although Bloopers normally appear only in water levels, they can be placed in non-water levels just fine and will award a whopping 1,000 points when stomped. Most other "impossible" ways to kill enemies, like hitting a Podoboo or Bowser with a Starman, only award the default 200 points, though Podoboos also have the stomp code defined.
Given that Bloopers appear in non-water levels (such as World 1-3) in the Japanese Super Mario Bros. 2 and award 1,000 points, this behavior was likely intended all along.
5-1 Starting Castle#
For unknown reasons, most likely an oversight, World 5-1's starting castle is not the 3-tiered one as seen in every other world. This was not fixed in the SNES and GBC remakes.

- Just like in Vs. Super Mario Bros., Super Mario Bros. 2 and Super Mario All-Stars, in all underwater areas (Worlds 2-2 and 7-2 plus the underwater sections of 5-2, 6-2, and 8-4), a block was added in the European version over the exit pipe to close the one-tile-high gap. In the Japanese and US versions, it is possible to clip into that gap in Super/Fire form and get stuck in the wall with no way out other than letting the time run out.

- In World 8-2, the starting positions of the Koopa Paratroopas were changed.
- The Japanese and US versions had a bug where if a lot of enemies were on-screen, the Springboard sprite could load into a piece of memory normally used to load power-ups or the flag at the end of the level, allowing these to overwrite each other. The European version added a check to prevent this from happening.
- In the European version, the lowest position a Blooper can reach onscreen was lowered by 4 pixels, allowing them to, unlike other versions, hit Super or Fire Mario if he's standing on the ground.
- Originally in the Japanese and US versions, the branch of an enemy object would add 12 pixels to the player's vertical position. In the European version, it decides whether Mario stomped or got hit depending on the enemy branch of the enemy object.
- Mario's initial downward acceleration at the start of the level is higher.
- Mario's vertical acceleration on springs is now defined.
- The movement function for Cheep Cheeps was drastically simplified.
- In the European version, the vertical difference deciding whether Mario stomped or got hit depends on the enemy.
- Rather than doing an ASL (Arithmetic Shift Left) on the injury timer, the value is set explicitly.
- On water stages, Mario's vertical speed is set to 0 after nullifying.
- Some enemies (more specifically: Piranhas, Bullet Bills, Goombas, Spinies, Bloopers, and Cheep Cheeps) have a larger hitbox.
- The second tone of the coin grab sound effect is different.
