Golden Egg- the main editor

YI Sprite Sheet Editor

Y.I.P.E.S.- to edit the messages and level names

YCompress- if you want to insert the graphics after you edit them in YY-CHR or something.I on't know if there are better ones, but YCompress is a command prompt so you have to extract and insert graphics.

A text editor or Midring and Entrance editor.

I don't know if there are any more, but these are the main programs that can help you get started. I hope that helps.
I'll expand Lespna1's response a bit

I've been making a hack and I can't use the 3x9 falling block. I'm using them in the grassy area outside of the cave in 1-3 and have the right sprite set so I do not know why this is happening. It's no great issue but any help would be appreciated.
These Sprites' locations in the editor do not represent the top-left corner of the Sprite in-game as one might think they do. Try moving the Sprite around a bit and see if it works afterwards. Maybe there are also too many surrounding Sprites.
If it still doesn't work after moving it around several times, please post a screenshot of the level in the Editor, so I get a better idea about what is going on in the level.
As for suspecting the Sprite Set could be the reason: That's not possible; the Sprite Set only determines which tiles to pick for each Sprite, so you'd have glitched graphics instead of no Sprite.

Thanks! It worked after I placed it with 9 spaces above.
Is there a way to change the sprite sets in Kamek's room? I don't need to use this in my hack but I was curious if it could be done. When using Golden Egg before changing the sprite sets didn't change which sprites would be correctly displayed. (A sprite set that had Bandits had broken sprites for the Bandit)
How do you resize object BE (the sewage coming out of the pipe in the BG of the sewer tileset)? I see different sizes of it in the second room in 3-8, but when I select it and move the mouse all around it the cursor never changes from the 4 directional to the bi-directional.

Yeah, you have to adjust the size without the mouse. You can do so by pressing Shift + Up/Down Arrow key, or in the menu Edit > Increase/Decrease Height.

I was just playing around in the sprite set editor and I think I found that the zeus guys need to be in the second slot down and the boo guys carrying the bombs are in the fourth slot down. Don't know if anyone has found this out but I just wanted to toss it out there.

There are some sprites that need specific "positions" in the sprite set
Here are all of them(counting up to down!)(also included the ones you mentioned)

Zeus guy: 2nd slot

Tap-tap: 6th slot

Boo guys carrying bombs: 4th slot

Huffin' Puffin(Small duck): 1st slot

Flamer Guy: 6th slot

Baseball guys: 4th slot

Lantern Ghosts : 6th slot

Grunt : 6th slot




edit: huh? I didn't noticed that typo when posting...

EDIT: I just tried inserting sprite 1D4 in an otherwise unmodified 1-4 (The sprite is named Slow auto-scroll in Golden Egg) and the screen kept scrolling until screen 7E. It stopped there. I'm not sure how your auto-scroller goes back. That's kinda weird!


It turned back around after going left from 0F and reaching screen 01. Afterwards once it started scrolling right it did in fact stop at 0E. As for what you said about the hex-editing I don't think I have the time or patience to do that so I'm just going to tinker with the special auto-scrolls until I can decipher exactly which screens I'll need to place things in.
Yup, the scrolling is hardcoded and the first and last scrolls are special scrolls, because the Y-coordinate is not fixed. All the other scrolls have both coordinates hardcoded and you can freely edit them.

Hey I was wondering if there is a way to change the sprite sets in Kamek's room. I tried using different sets like those with Bandits or Flower Pots but they wouldn't work even with a proper set.
There should be a way, but I haven't found it, yet...
Setting the Level Mode to Kamek's Room pretty much pre-determines everything for you. I've found a matching Sprite Set, which is Sprite Set 0x79 at (headered PC) 0x350F: [67 3C 55 1A 1A 29]. Now, one might be tempted to think, that this Sprite Set Index is referenced when a Level is Kamek's Room, but that is not the case; I've tried and edited it and nothing glitched. I assume the Sprite Tileset is hardcoded and loaded differently from a normal Sprite Tileset.

Darn#ab{:(} I had hoped to use it in 2-8 with flower pots and Boos but I guess that idea will have to go, just like many others...
One more thing. Can the pond water be used outside of the Pond tile-set? Like could you use it in a flower garden? Just asking so that I won't have to redo any levels due to an error.
The subroutine responsible for loading the sprite graphics in Kamek's Room begins at 36D3 in a headered ROM (SNES $00:B4D3).

Points of interest:
36E2 [67] Value for 1st graphics file (Kamek)
36E7 [3C] Value for 2nd graphics file (Boo Guys operating rotating spike bar)
36EC [55] Value for 3rd graphics file (Lantern Ghost, Sluggy, Fang)
36F1 [1A] Value for 4th graphics file (Hookbill hills)
36F6 [1A] Value for 5th graphics file (Hookbill hills)
36FB [29] Value for 6th graphics file (Milde)

Thanks for that info! It's good to know what I'll be able to use. I've never hex edited but I think I may just give it a go to at least fill those two slots with other sprites. If this was done do you think that the potted ghost boss could be used in Kamek's room? I've seen videos of people editing the area with this boss so I am curious.
Speaking of hex editing, what would it require? Is there a certain program that is used to edit Yoshi's Island and related games? If I hex-edit the rom will it still work if I later want to use the sprite set or message editor? Sorry if these questions are elementary to you all but I've never hex-edited before and so I don't know what to do.
