Makes the sprite background used in the Overworld border use 4 16x16 tiles instead of 16 8x8 tiles, saving some OAM slots (slots $10-$3C in $0200) at the cost of using a bit more sprite GFX space for it.

Upsidedown Slope Tiles work in Normal 1 and 2 Tilesets
Pretty much what it says on the tin. Allows the map16 tiles that are used in upsidedown slopes to work in the Normal and Normal 2 tilesets. Note that this breaks the slanted pipe object, as it uses those extra slope tiles.

Makes layer 1/2 priority against sprites work in vertical levels.
Details
Enable Continuous Yoshi Flight
Makes winged Yoshi continuously ascend when jump is held, as if Mario has cape, even if he doesn't.
yoshi
Details
Remove Score Sprite Delay
For some reason, there is a small delay between a score sprite appearing and the score actually registering. For example, if you have a goal tape in a vertical level and you get the 3-up prize from getting 50 bonus stars, the 3-up won't actually register. Same thing if you die while collecting a 1-up shroom or 3-up moon at the same time. This hex edit should remove that delay, thus fixing this bizarre issue. However, if you collect a fishin' Lakitu's 1-up in the death animation, the 1-up still won't register.
Details
Change "Nintendo Presents" Timer
Changes how long the Nintendo Presents screen will remain active. Timer is given as the number of frames, and a value of 0 will last for 256 frames instead.

Throw Block Splash Fix

Details
Change Exits Count
Changes the number of exits required to display the "☆96" tiles on the file select menu.
Details
Sprite Interaction on Left Edge of Screen Fix
Causes sprites to retain interaction with Mario even while marked horizontally offscreen. This is only needed for sprites which don't already interact with Mario every frame (like platforms).

This is especially noticeable for large sprites, like Banzai Bills, which will be marked offscreen and not interact with Mario when their left edge is offscreen, even though much of the rest of the sprite is still visible.
bugfix sprite
Details
Remove "TIME UP!"
Removes the "TIME UP!" message when Mario dies after timer reaches zero.

Amazing Flyin' Hammer Bro Throwing Hammers on Lava Fix
This fixes a bug that if you defeat an Amazing Flyin' Hammer Bro and it falls into lava, the sprite will still throw hammers.
bugfix
Details
"S" Letter with Misplaced Palette Fix
This fixes a bug where the letter "S" in the "MARIO/LUIGI START!" message uses palette row 8, instead of palette row A like the other letters. As you might guess, this will make the "S" also use palette row A. Note that newer versions of Lunar Magic already fix this.
bugfix
Details
Remove Bonus Star Timer 1-UP
Removes the weirdly specific feature where if the tens digit of the player's bonus stars matches with the timer's tens and ones digits when finishing a level, they will be rewarded with a 1-UP. This can and will also happen if the player has less than 10 bonus stars and they clear a level that has no time limit (since the tens digit of the bonus stars matches with the timer, 0 - 00). This tweak removes this feature, fixing the issue mentioned earlier.

Change Dragon Coin Worth
Changes how many coins the player gets from collecting a dragon coin.

Carriable Sprites Through Pipes Fix

bugfix
Details
Change Starting Lives
Changes the amount of lives the player will have when the game starts. Note that values greater than 100 will cause the lives counter to show glitched graphics.
Details
Double Key Jump Fix
This mitigates a very niche glitch that prevents Mario from jumping when interacting with the top of two keys at the same time.

More detailed explanation: When $1471 is set to #$02, it will force a specific behavior used by the Portable Springboard and Pea Bouncer sprites, which lets the player stand but be unable to jump. This is because those sprites are intended to "release" Mario automatically.
When Mario steps on a Key/P-Switch, it doesn't force $1471 to a static value of #$01 like other rideable sprites; it increments the value instead. So if two Keys are simultaneously touching Mario, the value is set to #$02 instead and locking Mario's jump.

These modifications force the behavior to apply to negative values of $1471 instead, and then forces the Portable Springboard and Pea Bouncer to write a value of #$FF instead of #$02 to $1471. This may require some tweaks to disassemblies or sprites based upon the Springboard/Pea Bouncer sprites. If you wish to detect this hijack within custom resources:
Code
if read2($00D60E) == $0E30
	;; hijack detected
endif
