1 byte |
Blocks |
A flag that is set when the player is on a note block that is currently going down, i.e. the bounce sprite is moving downwards. If this wouldn't be set, the player would be pushed away from tile 152 (the tile that temporarily comes into place of the note block). |

1 byte |
Flag |
If "vertical scroll at will" is enabled, then this flag controls if the screen should scroll up to the player. If you set this to a non-zero value every frame, it can be seen as a temporary alternative to setting $00:F878/0x7A78 to #$80, since the latter is permanent. |
|
$7E1405
|
1 byte |
Flag |
Indicates that the player is just about to warp to another level via a pipe, and whether or not Yoshi should be drawn at that point. It is set as soon as $7E:0088 reaches zero, and if Yoshi is inside the warp pipe too, his graphics will be hidden. |
|
$7E1406
|
1 byte |
Camera |
This is set to #$80 if you bounce off of a springboard or a purple triangle (while on Yoshi, that is), and is cleared when touching the ground.
The game uses this, along with some other RAM addresses, to determine if the screen should scroll up with the player or not. |

#$F8: the stage when not holding the right or left button
#$F4: Partially aiming towards floor
#$F0: Almost completely diving
#$C8: Diving completely, the stage where you cause an earthquake where you land.
When set to #$C8, the player will gain the large upwards boost (instead of the little normal boost) when cathing air. |

1 byte |
Flag |
Keeps incrementing in the Reznor battle room. It is used as a flag to determine that a different OAM index needs to be used for a smoke sprite or a puff of smoke, to make sure there's no conflict with the platform tiles.
However, since this keeps incrementing and thus sometimes hits #$00 again, it can occur that a platform tile disappears for one frame when a smoke sprite is shown. |
|
$7E1410
|
1 byte |
Flag |
Yoshi has wings flag #1 (the other is $7E:141E). #$01 would mean that the player with a fire flower powerup can shoot fireballs while on Yoshi (never occurs in the game), whereas #$02 indicates Yoshi has wings.
Note that this one only handles graphics of the wings (value #$02), and that it disables the Yoshi tongue action (value #$01).
The value from $7E:141E is stored here each frame. |

Camera |
The base vertical offset of Layer 2 from Layer 1, when vertical scrolling is enabled for it. This is calculated based on the type of vertical scrolling set in $1414, using the initial FG/BG positions stored to $1C and $20:
If $1414 is #$01 (constant), then this is: $20 - $1C
If $1414 is #$02 (variable), then this is: $20 - ($1C / 2)
If $1414 is #$03 (slow), then this is: $20 - ($1C / 8) |
|
$7E1417

2 bytes |
Camera |
The distance to scroll layer 2 vertically if that kind of scrolling is enabled. This is calculated based on the type of vertical scrolling set in $7E:1414. The scrolling is calculated as follows:
If $7E:1414 is #$01 (constant), then $7E:1417 is: $7E:0020-$7E:001C
If $7E:1414 is #$02 (variable), then $7E:1417 is: $7E:001C >> 1 ^ #$FFFF + 1 + $7E:0020
If $7E:1414 is #$03 (slow), then $7E:1417 is: $7E:001C >> 3 ^ #$FFFF + 1 + $7E:0020 |

1 byte |
Yoshi |
How Yoshi should go inside a pipe.
#$01 = Duck a little (horizontal pipe).
#$02 = Face the screen (vertical pipe).
#$FF = Don't change image, only go behind layer (shooting out of slanted pipe). Note that this will probably work with all values #$03-#$FF.
An immediate effect of this is that Yoshi goes beyond layer 1 with any non-zero value. Also, Yoshi's tongue isn't shown either. This is still set even if the player isn't mounted on Yoshi, it also affects the position of carrying sprites through pipes. |
|
$7E141A
|
1 byte |
Counter |
Counter that increments every time a new level is entered (with a door or pipe) - this enables you to distinguish the 'mother'-level from sublevels, as this always is zero at the start of a level. Note: Don't enter a sublevel within a level 256 times, or a glitch will occur. |
|
$7E141B
|
1 byte |
Flag |
Determines if you have played the bonus game before in the same level before. If it is non-zero (meaning you've played the game before), all blocks in the coin game will always be incorrect.
Note that if you don't hit a single block the first time playing the game, then this will be zero, and you can play the game again. |
|
$7E141C

Yoshi |
Yoshi has wings flag. The only possible value for this address in the original is #$02, but setting to #$01 will allow the player to throw fireballs if on Yoshi, even if he is not fiery. This will, however, disable flight as well as Yoshi's tongue attack.
It's recalculated each frame. |

Timer |
Used to determine whether or not the victory walk should display the number of collected bonus stars. If it is zero (see also $7E:1900), the amount of collected bonus stars is not displayed. Otherwise, it is. $7E:1900 is stored to it, causing this address to decrement as well. Also note that this value does NOT have any effect on the rest of the bonus text. |

Sprites |
Layer 1 X speed used in the scrolling codes.
#$0001-#$7FFF = move left; #$8000-#$FFFF = move right. #$0000 means there is no movement.
Effectively, it's the X speed to give the player when he's touching the side of a screen, during a level which does not have regular Layer 1 scrolling. Values are different depending on the type of (auto-)scroll.
This value divided by #$10/#16 is stored into $7E:007B.

2 bytes |
Sprites |
This is used internally by the scroll sprites for updating the layer 1 X position. In particular, the routine at $05:C4F9 uses it to add the current speed to.
Furthermore, $7E:144E is used on the overworld to determine after how many frames the player should face the screen again after settling on a level tile.
$7E:144E is also used in the credits, as a timer that is set to #$06 and decrements every frame. If this is zero, bit 0 of $7E:144F will get flipped, causing Peach's image during the walking phase to bounce.
$7E:144F is a flag that makes Peach bounce during the time she walks in the credits.

This is more notable in auto-scroll commands, for example, if $7E:1462 were to remain static while there was a Layer 2 auto-scroll going, the image would stay, but the level would move.
Is also used for temporary storage to determine how much the screen has moved horizontally in the current frame. ($7E:001A - $7E:1462 = $7E:17BD) |

Layer 1 Y position, next frame.
Much similar to $7E:001C.
Is also used for temporary storage to determine how much the screen has moved vertically in the current frame. ($7E:001C - $7E:1464 = $7E:17BC) |

Layer 2 X position, next frame.
Much similar to $7E:001E.
Is also used for temporary storage to determine how much the screen has moved horizontally in the current frame. ($7E:001E - $7E:1466 = $7E:17BF) |

Misc. |
Used to determine how much layer 3 has moved horizontally in the current frame. This address is only used during the credits while displaying the enemies for the windowing HDMA.
Also used by Lunar Magic to hold the Layer 3 Initial X position/offset. |

Flag |
Carrying something flag. Very similar to $7E:148F, with the difference that, if this flag is set, the player's graphics don't change, and throw blocks can still be picked up as long as $7E:148F remains zero. If used in a carryable custom sprite to check if the player is already carrying something, definitely combine it with $7E:148F to assure there are no exceptions.
#$00 = Carrying nothing; #$01 = carrying something. |

Misc. |
Whether the player is on top of a solid sprite, and what kind of sprite that is.
#$01 = Standing on top of a floating rock, floating grass platform, floating skull, Mega Mole, carrot top lift, etc. This one calculates the player's position based on the next frame.
#$02 = Standing on top of a springboard, pea bouncer. This one calculates the player's position based on the next frame.
There's a check at $00:D60B so that the player can hold the jump button pressed for a longer while to jump higher.
#$03 = Standing on top of a brown chained platform, gray falling platform. This one calculates the player's position based on the current frame. |

Sprites |
Left window X position of the extreme bottom of the spotlight.
Please note that this position is for the imaginary scanline #$FF, whereas there are normally only #$E0 scanlines on a screen.
That means that the value here is never equal to the left window X position on the very bottom of the screen, unless $7E:1476 is equal to $7E:1472, forming a straight vertical line. |

In the spotlight code, the left window X position of each scanline is calculated and temporarily stored here, after which this address stores its value to an even byte of $7E:04A0.
What is left at the end of every frame is the left window X position on the very bottom scanline.
This is used once in every four frames, probably to reduce lag. |

1 byte |
Sprites |
Used by the spotlight to calculate whether or not to move the left window on a particular scan line into the direction of the resulting X position on the bottom left.
It works by adding the width from $7E:1480 to itself (starting at #$00 initially), and if the resulting value is higher than #$CF (or even overflows, setting the carry bit), the left window moves a pixel into the direction of the resulting X position on the bottom left. |

Sprites |
Used by the spotlight to calculate whether or not to move the right window on a particular scan line into the direction of the resulting X position on the bottom right.
It works by adding the width from $7E:1481 to itself (starting at #$00 initially), and if the resulting value is higher than #$CF (or even overflows, setting the carry bit), the right window moves a pixel into the direction of the resulting X position on the bottom right. |
