Sprites |
Miscellaneous sprite table.
Certain powerups use this table as a blink-fall flag.
#$00 = Off; #$01 = On, powerup will blink and fall straight down.
The game stores #$01 here when it drops the reserved item from the item box. The blink-fall flag affects the Super Mushroom and the Fire Flower, but not the Cape Feather. The blink-fall flag also affects some other sprites, at least the Starman, the 1-Up mushroom and the coin sprite, but these sprites might glitch if you set the flag.
One glitch is that the blinking sprite-coin permanently occupies a sprite slot if it falls off the level, so that it might prevent the spawning of other common sprites.
Other than that, this address has many different purposes. More information can be found here. |

$7E1540

12 bytes |
Sprites |
Miscellaneous sprite table. Table decrements itself once per frame, except for carryable sprites, where it decrements every second frame (the code at $0196D7 “slows” the timer by 1/2 by incrementing it every even frames ($13), which results in a decrement every odd frames).
Various sprites use this table as a stun timer. For example, this timer controls when flipped Goombas and squashed Mecha-Koopas decide to rise and walk. This table is also the sprite spinjump death frame counter - that is, how long to show the "spinjumped" image when the sprite is killed by a jump of such sorts. More information can be found here. |

Multiple coin block timer - amount of time until the multiple coin block turns into a used block. Keeps decrementing until it's #$01, after that it stays that value until the block is hit again, at which it's turned into a used block. Then, this address gets set to zero. |

Sprites |
Sprite off screen flag table, vertical. For sprites in bank 1, if the sprite is set to be two tiles high (with $190F), then bits 0 and 1 correspond to the top and bottom tiles respectively.
The routine that sets this address in bank 2 and 3 has an error, however; this address instead does the 2-bit functionality if bit 5 of $1662 (which is one of the bits in the sprite clipping value). As a result, some sprites will register as vertically offscreen when they're actually just at the top of the screen. |

1 byte |
Sprites |
Indicates where the player is on the X axis in relation to the currently-active revolving net door sprite. If this is #$00, the player is perfectly centered on the sprite horizontally. It will be positive if the player is toward the left side of the sprite (the farther left, the bigger the positive number) and negative if the player is toward the right side of the sprite (the farther right, the bigger the negative number).
Is used to calculate the player X speed as the net is turning around sideways. |

$7E1879
|
1 byte |
Empty |
Empty. Cleared on reset, titlescreen load, overworld load and level load. |
|
$7E187A
|
1 byte |
Yoshi |
Riding Yoshi Flag. #$00 = No, #$01 = Yes, #$02 = Yes, and turning around. |
|
$7E187B
|
12 bytes |
Sprites |
Miscellaneous sprite table. Has the following purposes:
Sprite stomp immunity flag table - enables stomp immunity for sprites if the flag is set.
Additionally, the changing item sprite uses it to determine which sprite it is (#$00 = mushroom, #$40 = fire flower, #$80 = feather, #$C0 = star), the goal tape determines by this address whether it activates the normal or secret exit, the radius of rotating chain sprites is held by this address, certain Yoshi abilities are handled, etc. More information can be found here.
$7E:1884 is also used to determine what background should be used during the Morton/Roy/Ludwig battle scene. #$00 = Ludwig; #$01 = Morton/Roy.
There is also a bug with the background flames during the Ludwig battle, as they seem to change color upon this address not being #$01. This is responsible for a palette glitch in the original SMW, where the fire turns a greyish blue very briefly. Change $02:8380 to #$80 to fix the bug. |

$7E1887
|
1 byte |
Timer |
Time to shake Layer 1. |
|
$7E1888
|
2 bytes |
Misc. |
Layer 1 image relative Y position, used by $7E:1887 (shaking ground). Does not affect Layer 1 interaction. #$0000 = default value, Layer 1's image unchanged. The higher the value (positive, #$0001 and beyond), the more Layer 1 goes up. The lower the value (negative, wraps around to #$FFFF and below) the more Layer 1 goes down. |
|
$7E188A
|
1 byte |
Empty |
Empty. Cleared on reset, titlescreen load, overworld load and level load, hurt, death, and taking hit while cape flying ($00:F625 for the last three) and in the Peach Rescued scene ($03:AE39). |
|
$7E188B
|
1 byte |
Player |
Player image-relative Y position, used by $7E:1887 (shaking ground). Does not affect player interaction. Unlike $7E:1888, this is an 8-bit address. |
|
$7E188C
|
1 byte |
Flag |
Flag that determines if the game should keep updating the tile and YXPPCCCT data for the sprite background tiles in the Morton/Roy/Ludwig room.
#$00 = Keep updating; #$01 = Stop updating. |
|
$7E188D
|
1 byte |
Misc. |
Used during the calculation of the X position of the background in the Morton/Roy/Ludwig room. It starts by copying the value from $7E:001A (8-bit) and getting the lowest bit from $7E:001B by using the carry bit. So first, this address is $7E:001A (9-bit) > 1.
This address is then, after it's inverted with EOR #$FF : INC A, used for $7E:0006 (scratch RAM, used for X displacement of all tiles). |
|
$7E188E
|
1 byte |
Empty |
Empty. Cleared on reset, titlescreen load, overworld load, cutscene load and level load. |
|
$7E188F
|
1 byte |
Sprites |
Used to indicate whether the bonus game is over. It will disable the interaction and movement. |
|
$7E1890
|
1 byte |
Counter |
How many 1-Ups to spawn. (Used for bonus game.) |
|
$7E1891
|
1 byte |
Timer |
P-balloon timer. Ticks down one step per four frames.
Note that setting this doesn't make the player fly away. The flight controller is $7E:13F3. |
|
$7E1892
|
20 bytes |
Sprites |
Cluster sprite number. The pointer for those is at $02:F825. A list of possible values, as well as more information on cluster sprites in general, can be found here. |

$7E18A6
|
1 byte |
Empty |
Empty, unused RAM. Referenced at $01CF9E (Morton's code) but never actually used. Cleared on reset, titlescreen load, overworld load and level load. |
|
$7E18A7
|
1 byte |
Blocks |
This address is a mirror of $7E:1693, which holds the Map16 number of the current block that is being checked. Primarily used in the Chargin' Chuck turn/throw block detection code. |
