Sonic 2 Dynamic Palettes (GitHub/Hg disassembly)

Let's see how to use different palettes in act 1 and act 2 of sonic 2.
 
Search PalLoad1, PalLoad2, PalLoad3_Water, PalLoad4_Water.
Replace every "lea (PalPointers).l,a1" in this:




move.b (Current_Act).w,d1 ;Check  Current Act

cmpi.b #0, d1  ;Is it act 1?

beq.s @act1      ;Load Act 1 Palettes

cmpi.b #1, d1  ;Is it act 2?

beq.s @act2      ;Load Act 2 Palettes

@act1:

lea (PalPointers).l,a1

jmp P* ;Continue

@act2:

lea (PalPointers2).l,a2

jmp P* ;Continue

P*:

;[the continue of PalLoad]



Now copy and paste the array "PalPointers" and name the copy "PalPointers2".

Rename every palette in PalPointers2!

Create palettes for Act 2:




Pal_EHZ2: BINCLUDE "art/palettes/EHZ2.bin"



and config SonED2 or SonLVL for act 2 palettes.

 

This guide is similar to PsychoSk8r's one... How about Xenowhirl's disassembly? Most people use it. But anyway, tutorial will be useful to some people.
