Trying to change the palette of the SMB3 Brown Platform...please help - ASM & Related Topics

Hello,

Among the new custom sprites I recently inserted into my hack, one of them was the brown platform from SMB3 that moves to the left (usually) but falls when the player jumps on it.

Anyway, I'm having some difficulty changing the palette of this custom sprite, since it uses palette 8, the sprite seems to be refusing to let me change its palette in the cfg editor, no matter how many times I change it and save.

The reason I wanted to change its palette is, I'm making a new level where it has these platforms, and the SMB3 moving clouds (from 6-2) in one of the areas, and I want to have them looking the same (basically, a moving cloud which stays in the air, and one that falls if it's jumped on), just so that even an alert player will be unable to tell the difference without jumping on one of the moving clouds.

I'm wondering if the palette of the brown platform has to be changed in the ASM file in order for it to be changed? If so, could someone point it out to me, please?

Thanks in advance.

It's possible that it's hardcoded into the sprite.

First off, what do you mean it won't save when you change the palette in the CFG editor? Does it stay 8 when you open the CFG again?

If the sprite stays palette 8 in-game regardless of what the CFG editor says, then the palette is hardcoded. Not hard to fix if you know where you're looking. Each tile can have a different palette, and it's set in the GFX routine. It will look similar to this, but not necessarily exactly the same.

Code

               	LDA $15F6,x             ; get sprite palette info
              	ORA $64                 ; add in the priority bits from the level settings
             	STA $0303,y             ; set properties

The LDA $15F6,x is what's important. That pulls the palette value from what's in the CFG. If that's not there, then the palette is determined somehow else. Do you know enough ASM to change it yourself? If not, you'll have to post the code in the sprite so we can fix it for you.

I guess I should have worded things slightly better, anyway, the cfg editor saves the palette change whenever I save the cfg, even if I close the cfg editor and re-open it up with the cfg file for the brown platform, so I'm starting to think it must be hardcoded, as it seems that changing its palette in the cfg editor has no effect in LM unless I manually change at least one of the colours in palette 8.

Usually I'm good at minor tweaks with sprites in their asm files, but in this case, I'm going to have to post the contents of the ASM file. On a side note, I did find something similar to the small bit of code you mentioned.

SUB_IS_OFF_SCREEN LDA $15A0,x ; \ if sprite is on

screen, accumulator = 0
ORA $186C,x ; |
RTS ; / return

Sorry if this is too big for anyone, but I'm thinking the area I need to make the palette change is somewhere where it says PAL/GFX page.

Usually the palette of any sprite is in the GFX routine, like the one from your sprite:

;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
; sprite graphics routine
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;

FallingPlatDispX dcb $00,$10,$10,$20

FallingPlatTiles dcb $85,$86,$86,$88

Changing most of those values only affect the positioning of the GFX and the graphics of the moving platform itself. So, I'm guess it's somewhere I or anyone wouldn't look.

I'm certain the area I'd have to change is within that smaller bit of code there, anyway, since Koyuki made this sprite, hopefully I'll be able to get some input from her on this one.

Extras

I should have something witty to put here (even if it's just to update dated info), shouldn't I?

After looking at the sprite, I assume that you don't want the palette to be 9. So the value you would want to change should be $x2 or $x3 (grey palettes, 1st and 2nd page respectively), which is usually placed near the tilemap info in the ASM.

But I can't exactly find the damn thing myself, thanks to my limited ASM knowledge. However, the following list are values you can replace the x in $yx, for example to change its palette in the case something is hardcoded.

0 = Gold palette (first page)
1 = Gold palette (second page)
2 = Grey palette (first page)
3 = Grey palette (second page)
4 = Yellow palette (first page)
5 = Yellow palette (second page)
6 = Blue palette (first page)
7 = Blue palette (second page)
8 = Red palette (first page)
9 = Red palette (second page)
A = Green palette (first page)
B = Green palette (second page)
C = Palette E (first page)
D = Palette E (second page)
E = Palette F (first page)
F = Palette F (second page)

Also in the case with some sprites, you may need to change the hardcoded palette value and it's CFG palette. I hope that info is of some use to you.

LDA #$01 ;Sprite PAL/GFX

I think you need to change that. It's YXPPCCCT in binary.

Y = Y Flip.
X = X Flip.
PP = Prority (00 being lowest, 11 being highest).
CCC = Palette;

Palette 8 - 000
Palette 9 - 001
Palette A - 010
Palette B - 011
Palette C - 100
Palette D - 101
Palette E - 110
Palette F - 111

T = Sprite graphics page. 1 makes it use SP3/SP4.

So you finally get your 8-bit value, e.g.:

01010010

And convert that to hexadecimal using your Windows Calculator. You would then add that instead of 01. For example, I would use 52.

If you don't want it to be hardcoded though, make it load $15F6,x instead.

Thanks MrDeePay and IceYoshi, with your combined help, I got the palette I wanted for the cloud I tweaked that falls when jumped on. Even though the grey areas are slightly different than that of the SMB3 equivalent moving cloud, I think these two platforms will work well for the element of surprise.
