All of the gibberish level names point to [2F 53](11552F). The first copy of this pointer in each world is for the Bonus Challenge slot. The isolated [2C 4A] in World 1 is for the "Welcome to Yoshi's Island" level.

TIP: Remember that most pointers are byte-swapped and in SNES format!

To correct the side effects of changing the Bonus challenge icons into levels,
make the following changes in parentheses:

Older info:

BF7DB: Midway start data
BF671: Main Start Data

1BB: Change to (Grass Graphics/Green Palette X&1)
1BC: Change to (Submarine Graphics/Sub Palette X&1)
1BD: Change to (Castle Block Graphics/Red Palette X&1)

It should read as: A9 74 01 22 64 A3 03

This requires a bit of ASM
The first loads the LDA.
The second loads the sprite that it generates
The third determines whether the Y location is odd or even
The forth is the long addressing mode
The last three are the subroutine, inverted

8C539: What the Mini-Game Bandit (Seed Spit) Shoots after comsuming a watermelon
8C576: What the Mini-Game Bandit (Seed Spit) Shoots after comsuming a red watermelon

there should be 5 bytes before the A9
the first two, if changed to A5 10, means load a random number
The next (29), means use the logical operator AND
Other Stuff:

13753: When I changed this, the monkey that spits seeds runs away all the time...
1E185: When I changed this, Baby mario was in a different location...
138F6: When I ate the monkey that threw torpeados, after changing A9 D7 to A9 63, the game crashed, when I changed it to A9 D6, the monkey, rather than sweating sweat, it sweat fire

A9 XX XX 22 31 must control what an enemy generates when it hits water, lava, or does various other things

D6 - Fireballs (As in, the ones generated when something falls into lava)
D7 - Sweat
D8 - Smoke

I've made great use out of all this info.

However, I noticed one more side effect to changing the Bonus icons to Secret levels. Whenever you exit out of the Secret level or get the goal, the green Yoshi on the map will appear in the wrong spot until you move to a different spot. Here's a screen of the issue...



As you can see, the green Yoshi gets moved to another spot after exiting the Secret level, and stays there until you move elsewhere. Is there a way to fix this?

Also, I was wondering if each level had pointers to message box text. I wanted to allow a level that didn't have message box text to point to a location that does.

It seems that I've exposed yet another thing that the programmers overlooked. Yes, the glitch Golden Yoshi described happens in the normal game too.

6F5E8-6F6F3 Ending text
7D17E-7D76D Story text

As for why the credits text can't be found--it uses the sprite Layer. For some reason, I'm having a much more difficult time finding sprite tilemaps in YI than in SMW...

Wow...amazing how I never noticed that glitch. Oh well.

It's weird that it only happens for Extra 3.

Anyway, thank you.

It happens on Extra 1, too (see Green Yoshi slightly off the level mark?). I noticed this back when I had this game on the SNES way back when. I assumed back then that thats where those levels were on the map, since when you select them, they never show what Yoshi or where on the map those levels were.

These are great offsets and info, guys. I'll dig up the info I've found back on SMW central and bring it here when I get back home.

One question though, it may already been discovered but i overlooked it. Does anyone know the offset to change Baby Mario's crying sound? I want to disable it in my project. Thanks in advance.

Hah, I never even noticed the out of place Yoshi in Extra 3 until now.

A project, B.B. Link? Are you working on a YI hack? That'd be quite nice .

Yeah. Been fiddling around with Eggvine for a while now. Mainly just moving/adding stuff on the original levels and trying to get used to Eggvine a little more. I got some ideas I want to try in SMW2, and with these offsets and info, they just might work. I got the intro and 1/3 of level 1 done. I might show some screens in the general screenshot thread later. (if they have one here)
