Edit:
@Yoshis Fan
The extra flowers should count as long as you change:
0x0EB4C3 = Limit
0x01D183 = MaxFlowers * 2
0x01BB92 = MaxFlowers
0x01B82E = MaxFlowers * 2 + 0x50
The max score is still 100
and the goal does requires a FX modification.

The Y-axis carries over from the battle before.

@Yoshis Fan
Im working on 3 sprites,
One will add 0xFFD8 instead of 0x0010 to Kamek's Y-axis,
a Kamek blocker
another Kamek blocker that allows one more pass.
There is a difference of 56 pixels for the Y-axis, in secret 6 on the GBA.

@Yoshis Fan
Yes I am using the 0x1BA-0x1FF sprites, Kamek's sprite is being modified to work with the blockers. The first one will stop Kamek and with no final pass,
like the GBA one in secret 6 just above the area in the screenshot below

To get a 1-up(non bubble)
Change 0x0F8EAC from 0xB7 to 0xBE
To prevent it from moving, either change:
0x03C1B0 from 0xF0 to 0xD0 -swaps X type movements
or
0x03C1AE from 0x10 to 0x00 -Both X types don't move

Originally posted by Yoshis FanWorld Maps' Tilemaps
Where are the tilemaps of each world map stored? They consist of Layer 1 and Layer 2 tiles. For example in World 1 the Level Points, the paths, the chomp sharks, some hills, some clouds, the cave mushrooms, the white flowers and the 1-4 and 1-8 castle are Layer 1. Some clouds and hills, some tulips, small hills and rocks are Layer 2. I think they have got different tables for each world, one for Layer 1 objects and one for Layer 2 objects.
The map tile data uses the same compression as the sprites,
If you already decompressed the sprites using Ycompress, then all you need to do is open the ALLGFX.bin file in a hex editor.
World 1 compressed data starts at SNES 0x5B2BAB ROM 0x1B2DAB and decompressed data at ALLGFX 0x11DE00
World 2 compressed data starts at SNES 0x5B35C3 ROM 0x1B37C3 and decompressed data at ALLGFX 0x120E00
World 3 compressed data starts at SNES 0x5B3C69 ROM 0x1B3E69 and decompressed data at ALLGFX 0x122E00
World 4 compressed data starts at SNES 0x5B457B ROM 0x1B477B and decompressed data at ALLGFX 0x124E00
World 5 compressed data starts at SNES 0x5B4D88 ROM 0x1B4F88 and decompressed data at ALLGFX 0x126E00
World 6 compressed data starts at SNES 0x5B561D ROM 0x1B581D and decompressed data at ALLGFX 0x128E00
All data gets decompressed by the FX Chip, SNES 0x08A980 is the address of the decompressor.
Data gets decompressed to 0x705800, then a DMA copies from here to VRAM

If you want I can also find the all the Yoshi positions.
Edit:
Now a overworld editor needs to be created.

Here are all 1024 tiles and what they look like for all 6 worlds
palettes are not correct in image.
I was also thinking about adding tiles after the X-8 Castles for the extra and special levels.
|
|
|
|
The first 2 bits of the second byte are used with the 8 from the first for 1024 tiles.
Byte 1 Byte 2
TTTTTTTT-VHLPPPTT
T = Tile, 1024
P = Palette, 8
L = Layer priority
H = Horizontal flip
V = Vertical flip
The icons differ in all worlds, there are two slots used for them shown in the image.

SRAM modification
Here is a xkas patch that allows YI to save the number/type of eggs, lives and coins you collect per file.
You only need to complete a level to save the values.

I have tested it, haven't seen any side effects, it works well per file.
You can test the SRAM manually by changing values in the .sav file
File 1
0x7F80 <- [0C 00 25 00 25 00 24 00 24 00 23 00 23 00 E7 03 63 00]
File 2
0x7FA0 <- [0C 00 24 00 24 00 24 00 24 00 24 00 24 00 64 00 63 00]
File 3
0x7FC0 <- [0C 00 23 00 23 00 23 00 23 00 23 00 23 00 32 00 32 00]
File 1 should have 6 eggs, 2 green, 2 yellow, 2 red, 999 lives, 99 coins
File 2 should have 6 eggs, 6 yellow, 100 lives, 99 coins
File 3 should have 6 eggs, 6 red, 50 lives, 50 coins

Getting the eggs the right color and amount was the hardest part.
There was no check for a new file, now there is one.
The way to determine if a file is new or has a save is to check these
SRAM 0x7C02 File 1
SRAM 0x7C6A File 2
SRAM 0x7CD2 File 3
If the value is >= 0x80 the file is new other wise it has save data.
Edit:
@Zeldara109
Here is how to make the intro play music from the header
change:
SNES 0x01B0D7 ROM 0x00B2D7 from [8D 4E 01] to [EA EA EA]
Or you could change the hard-coded music:
Prologue -still works with 0x01B0D7 NOPed
SNES 0x10DB70 ROM 0x085D70
Level part
SNES 0x01B0D6 ROM 0x00B2D6
Here is a patch that will stop Kamek
For Kamek to stop attacking 2 conditions must be met:
1). You must be in the normal Yoshi form.
2). Kamek must pass sprite 0x1FF.

Here is the progress on the overworld editor I've been working on
Supports:
Editing BG 1 Layer
Editing BG 2 Layer
Editing Yoshis positions
Imports/Exports world tile data
Toggle BG1/BG2/BG3/Sprites
Does animations
Grid boundaries
I would like to know what features others want to see in the overworld editor, so I can put them in before I release it.
Can anyone confirm that there is a missing tile on the world 1 BG 2 layer?
I have checked several versions, and even have seen this in YI walkthroughs on Youtube 5:38

You can use Tile Molester for that, use codec 4bpp planar, composite (2x2bpp)
Then for the palettes, you can import from a ZSNES save state
Here is a link Tile Molester 0.16

Yes, In addition to the overworld editor I am also adding a editor for the rotating 3D stuff in the title screen back ground
Title Screen 3D BG editing
Here are the addresses for the sprites/ rotating objects

Some objects are hardcoded like the Yoshi, Seagull, Volcano Smoke, Y-Flags, and ruble, but are still easy to edit.
These are the addresses for the ground tilemaps
Light
ROM 0x1F9A00
ROM 0x1F9DFF
Dark
ROM 0x1F9E00
ROM 0x1FA1FF
Edit:
Here are the tile map sets, these can be found in the ALLGFX 0x144E40, using codec 4bpp linear, reversed-order
and in ram at 0x7E8BBE, using codec 8bpp linear.
Light
Dark
I took the time to put the maps together
Light
Dark
As for the overworld map editor
Right now it supports:
BG 1 Editing
BG 2 Editing
BG 3 Editing
Yoshi position Editing
Hacks:
Fix green Yoshi offset bug
World limitation hack -support for easy 1-5 world setup
Change event triggers like the darkword and others
Can edit the Mini-Game code button sequence
Not done yet:
Yoshi walk paths.
Assign different palette indexes to Yoshis
Add icons to blank buttons
Add preview to world selector
Make GUI better looking
And others as I think of them.
