I found these RAM addresses online.
So I reversed the order of the bytes in some of the above addresses, and found a few results in the rom for those values.
Therefore, I'll get back to this thread with some disassemblies and rom addresses for default values, if I can. I can't promise anything, because it's a strong possibility that finding the values in the rom was a coincidence, and that the addresses aren't referenced by out-right address.

In eggvine change objects 82 to S65.
If you want to keep all the red coins as tiles(Obj 82) you should change the palette index by -2, It works for 1-2, 1-7, right now they use the same palette as the pipes and egg spawning boxes.
I have copied the 16 bytes of memory from 0x070040-0x07004F to 0x070060-0x07006F and the green-red coins do look correct as yellow/red coins.

Yes, thanks, but at the other hand, sorry, because that has already been solved by changing the palette of the Tilemaps. I've forgot to update the GBA todo-list...  Of course I don't want to make them to sprites, because it is way handier to have them as objects, because there is no limitaion for them, then. Furthermore they cannot be differed so easily from the normal coins, so that's a good thing, too. There are two things, which must be done:
Correct 82's, 83's, 84's and X17's SFX, so they play the correct sound effect, when you take them. Another thing is, that they must turn into red coins, when the Magnifying Glass is used. For that, probably the ASM of the Magnifying Glass must be changed, so if you activate it, it changes the object palette of the coins (if there is no red as an object palette, it must be turned into sprite S65 by activating the Magnifying Glass).

The reason why the green coins sound wrong sound is that the code called when you get a green coin is run with wrong length of the index register, meaning that it leads to running some unexpected code. (This is easily fixable, though.)
Maybe Nintendo thought up the magnifying glass card later, and decided not to use, and to leave the green coin.
Although the standard palette has a red colours and it's theoretically possible to switch the tile palette to the red one by hijacking the routine which updates the BG1 VRAM when the display scrolls into the new area, I don't think it that realistic, because this might, or might not, cost some performance, as the new routine should be run almost every time you move. As for generating a sprite instead, I suppose this method is more unrealistic.
Why don't you use the sprite version from the beginning when you would compromise on using a sprite?

The thing is that the "green" coins are used for the GBA version. Since I want to make the hack Secret Of Yoshi's Island as similar to the GBA levels as possible I need the "green" red coins, because they are used in the GBA version wherever it's possible. But they are not bad in general, easily because of the thing, that they cannot be differed by normal coins this way and that's the intention of the palette. Do you think it's unrealistic to turn them into sprites, when the Magnifying Glass is in use? To my knowledge they are automatically turned into sprites, when Yoshi touches them. Well, another more "radical" way to solve the problem is to make, that the player is unable to obtain the Magnifying Glass. I think that would be a quite good idea, if everything else does not work. We could make the graphics look like the Egg-Filler and the item work exactly like it.
How do you correct the sound effect, by the way?
*Edit:*
Just in case someone tried to solve the following of my questions:
Originally posted by my profileControl Reverse Ghost
I want to use the control reverse ghost (Sprite 037) in my hack, but whenever I use him in a level, where you don't play the normal green Yoshi, Yoshi's palette ends up green or red, when you get rid of the ghost. Is there a way to fix that palette-changing? If not, the best thing would be to not change Yoshi's palette at all while the control reverse ghost sits on Yoshi's back. I have solved it. If anyone is interested: Changing the byte [BF] at 0x27D58 to [EA] will make, that Yoshi's palette remains unchanged while the control reverse ghost sits on his back. Other values like [00], [80] and [D0] do the same, but [EA] is the hexadecimal prompt to do no operation, so I guess changing the byte to [EA] is the safest solution.

@Yoshis Fan:
I found the sub routine that updates the BG1 VRAM from the main memory.

(Not the whole routine)
Romi was on to something about hijacking the subroutine.
some where along the line this goes to a code and stores a value of 0x0E40, 0x0E41, ~ 0x0E42, 0x0E43 to the video ram.
If a custom code could read in the show red coin flag and set the data according to the following info
Current - dont want any more
0x0E40 = tile 576, palette = 3
Target value - when show red coin flag is unset
0xA40 = tile 576, palette = 2
Target when - show red coin flag is set
0x640 = tile 576, palette = 1
red coin flag is memory address 0x701E06

Wait... I thought BRK freezes the game? (Does it do something different when SuperFX is involved?)
(By the way, I can think of one major advantage of editing the green coins to look and act like red coins-- to add red coins without having to worry about the sprite limit.)

The part at the end looked like a table, so I removed it. The other two was the disassembler assuming 8bit A (correct would be 16bit).

Nice finds! Now only the sound effect needs to be fixed and the coins must be affected by the red coin flag.

For YI ROM 1.0 and 1.1 patch using the following
Edit:For roms with headers add 0x200
//For all greed-red coins yellow 
0x000CD2A3 = 0x0A
0x000CD2A5 = 0x0A
0x000CD2A7 = 0x0A
0x000CD2A9 = 0x0A
//For all greed-red coins red
0x000CD2A3 = 0x06
0x000CD2A5 = 0x06
0x000CD2A7 = 0x06
0x000CD2A9 = 0x06
//To revert to green
0x000CD2A3 = 0x0E
0x000CD2A5 = 0x0E
0x000CD2A7 = 0x0E
0x000CD2A9 = 0x0E
Now I just need to change the pointer during the show red coin flag, and the sound effects.
Cool effect - show yellow coins every where a blank tile is 
0x000C33F2 = 0x40
0x000C33F3 = 0x0A
0x000C33F4 = 0x41
0x000C33F5 = 0x0A
0x000C33F6 = 0x42
0x000C33F7 = 0x0A
0x000C33F8 = 0x43
0x000C33F9 = 0x0A
to revert to blank tiles
0x000C33F2 = 0xFF
0x000C33F3 = 0x18
0x000C33F4 = 0xFF
0x000C33F5 = 0x18
0x000C33F6 = 0xFF
0x000C33F7 = 0x18
0x000C33F8 = 0xFF
0x000C33F9 = 0x18
Rom data from 0x0C0000 - 0x0CFFFF
This is the tile attributes data
each tile is 2 bytes 8 bytes for whole 16x16 block
bit 0-9 control the tile number
bit 10-12 controls the palette
bit 13 unused?
bit 14 H-flip
bit 15 V-flip
Didn't realize this was already mapped.

This information from the previous post isn't new and part of it is inaccurate. The address range of the "tile attributes" data in an unheadered ROM is from C33F2 to CD619.
Also, we typically use PC addresses for a headered ROM here, as that's what EggVine takes. This is why the range C35F2-CD819 appears in the post I linked to.
Bit 13 controls tile priority, which makes a tile appear in front of sprites if set.

Interesting! So most of the Map16 tiles, which are used by the Snow-Tileset have the 13th bit set, I suppose? Also, the muddy ground tiles of the jungle tileset got those set.
But then, another question: How many "free" Map16 tiles exist? You used tile 0x18E for object F7 and also told me that tile 0x53A was supposed to be used for the upside-down ceiling corner tile. So, since the space they use goes from 0xC35F2 to 0xCD819, and each of them is 8 bytes, there are 0x1445 (5189 in decimal) Map16 tiles.
By the way: Am I right, when I say that 0x80 8x8-tiles are loaded by default and 0x180 special 8x8-tiles are loaded per tileset?
*Edit:*

Sigh... Forget that... Doing this will make, that Yoshi won't pass Mario to another Yoshi, but will make that he passes him to the same Yoshi again, means both Yoshis have the same color at goal...

@Yoshis Fan:
This will hijack the routine that updates the BG1 horizontally.
red-green coins will show as yellow or red if you have the magnifying glass
still needs the up-down routine hijacked and possibly an all screen tile update.
This still needs to be optimized, will be done once all update routines are found, and I will create a IPS for this hack.

Thank you very much, tehaxor69!
If you can't get the palette inversion to work, you could make, that Yoshi's colors don't change at all. At the same time it should not affect the Yoshi at goal. Also, how is the sound effect changed? Romi said it would be a very easy thing to do that, because it's probably only a sound pointer, which must be changed. So hijacking Layer 1 is not the only problem, but it is the bigger problem. When it works once, it will be so great to be able to use the objects!

*Edit*
If you just want to disable the palette changes just set change the byte at 0x221B0 from 0x02 to 0x00.
Both codes will not effect the 2nd Yoshi at the goals.

Whoa, thank you a LOT!!
One question: Is there a fast way to apply the patch? The patches I get from Mattrizzle and Romi are Xkas patches. Yours are similar, but somehow they got more than just the opcodes and addresses and stuff. For the long code with the inversion: Are the .ORG 0x..... the PC addresses? Since I don't know how to apply the patch I hex-edit the ROM.
*Edit:*
Sorry, it's even harder to solve the problem: I use 16 different Yoshi-colors in my hack. The indexes 0 to 7, which normally use the palettes stored from 0x1FA240 to 0x1FA32F, then use the palettes of the Yoshis in the intro-scene, which go from 0x1FEFEC to 0x1FF03B. Doing this, indexes 8 to F use the palettes from the former indexes 0 to 7, then. 8 to F are freely editable then, because the palettes are the same, except the palettes of the intro scene got 16 colors each and the ingame palettes got 15 colors each. It might be useful to know how to do that tweak in order to make a patch:
This must be pasted from 0x79A7
| EC 4D 6C 4D | 8C 4D AC 4D | CC 4D 4C 4D | 0C 4E 2C 4E |
| 40 00 5E 00 | 7C 00 9A 00 | B8 00 D6 00 | F4 00 12 01 |
| 08 4E 88 4D | A8 4D C8 4D | E8 4D 68 4D | 28 4E 48 4E |
| 5C 00 7A 00 | 98 00 B6 00 | D4 00 F2 00 | 10 01 2E 01 |
At 0x003C73; 0x003D86; 0x026566 and 0x081D36
you must replace the [14 BA] with [A7 F7]
At 0x012E58 and 0x027D51
you must replace the [23 FB 04] with [C7 F7 00]
Oh, and another problem: Replacing the byte [02] at 0x221B0 with [00] will make, that Yoshi's palette becomes green, as soon as the ghost sits on his back.

I'll create IPS patches to make it faster. I'll create a Xkas patch if thats what you prefer.
The .ORG are the same as the offsets in eggvine.
The extra data is the oppcode size and hex code.
Change values at 0x221B5 [0x22 0x41 0xFB 0x04] to [0xEA 0xEA 0xEA 0xEA]
Would prevent the game from updating Yoshi palettes when touched.
The value at 0x221B0 changes the XOR value but the initial value is Green so that won't work, 0x221B5 would work fine.

Thank you very much for that! This one works! In case you still want to get the palette-change to work: Please make it so, that I can use it, because my hack got 16 Yoshi-colors. If you don't want that or you don't go for it anymore, then you don't need to make this patch, the main thing for me is, that the grim leecher works bug-free for any Yoshi. But I also don't want to spoil creating the patch for you and I appreciate it, when it finally works.

@Yoshis Fan:
Simple code is always better, and now you can use up to 128 Yoshi palettes that won't glitch.
*Edit* I might have under estimated that number, if all the indexes are 16 bit - 32768 would be possible(the palettes alone would be 1MB), 128 is enough to have a Yoshi palette for each level.

@tehaxor69:
Even 64 colors would be sufficient to have a single Yoshi-color for each level. However, thank you for it! But how do I apply it? I pasted the hex-code you noted at the end of each opcode from 0x1FFE7A into a clean ROM, but doing this, changes nothing. Do I also have to apply the former ASM tweaks you posted? And is there a way to apply it the fast way, other than hex-editing?
