Okay, credit to this guide goes to Cinossu, from SWS2B, as well as Shadow Fire, for adding a bit of extra information, seeing as Cinossu forgot some information needed, as well as writing it up.
You need to have some ASM knowledge to do this. You will also need to have individually edited palette files from SonED 2. Make sure to have them labelled correctly.
*****GUIDE STARTS HERE*****
Make copies of "Pallet pointers.asm" and rename them to "Pallet pointers2.asm" and "Pallet pointers3.asm". Make sure they're all in the "_inc" folder. Now, it's time to edit them. Open "Pallet pointers2.asm".
Change:
...into:
Save and close. Open "Pallet pointers3.asm" and do the same edits, only replacing 2 with 3. Save and close. Now, we move onto editing the main ASM file, called "sonic1.asm".
Open "sonic1.asm" and run a search for "Pallet pointers" (without the quotes), and replace the following lines...
...with...
Now, just below that, you should see a routine labelled "Pallet data". Move down to where "Pal_GHZ"'s routine ends. (After incbin pallet\ghz.bin) Create a new line and add the following...
The next line will show "Pal_LZ". Copy that data twice and paste underneath, being sure to rename it accordingly. In the end, this is how it should read...
Now, you need to navigate to the subroutine labelled "Subroutines to load pallets". Simply run a search to find this. You should then see the following...
Now, where the line "PalLoad1:" begins, replace the following line...
...with the following...
Note: "PalLoad#_Continue:" must be changed to whatever palette number you have pasted under. In this first case, it should be "PalLoad1_Continue". Do the same for the other PalLoad routines, only changing the PalLoad#_Continue numbers. If you did it right, you should see the following for all subroutines...
If that's all correct, save your ASM files and copy your new palette files into the "pallet" folder.
Now, you should be able to load dynamic palettes, but hold on, we're not done yet. I'm assuming you'd prefer to be able to edit the palettes in SonED2, depending on which zone's act you load. In this case, open up the following files in a text editor:
Now, locate the following line in each file:
We are now going to make a minor change. After <zonename>, simply place "2" for all act 2 project files, and "3" for all act 3 project files. To show an example, here's the contents of my ghz2.sep file:
Then, build your ROM and test. If you run into errors, you obviously made a mistake and forgot to do something. However, assuming you followed the guide properly, you should have dynamic zone palettes. Congratulations. You ownz!

If that's all correct, save your ASM files and copy your new palette files into the "pallet" folder.
Now, you should be able to load dynamic palettes, but hold on, we're not done yet. I'm assuming you'd prefer to be able to edit the palettes in SonED2, depending on which zone's act you load. In this case, open up the following files in a text editor:
project\ghz2.sep
project\ghz3.sep
project\mz2.sep
project\mz3.sep
project\syz2.sep
project\syz3.sep
project\lz2.sep
project\lz3.sep
project\slz2.sep
project\slz3.sep
Now, locate the following line in each file:
File: ..\pallet\<zonename>.binwhere <zonename> references which zone the palette belongs to.
We are now going to make a minor change. After <zonename>, simply place "2" for all act 2 project files, and "3" for all act 3 project files. To show an example, here's the contents of my ghz2.sep file:
Type: 1 Zone ID: 0 Act ID: 0 Object Def: objdef\s1obj 8x8 Tiles: ..\artnem\8x8ghz.bin 16x16 Tiles: ..\map16\ghz.bin 256x256 Tiles: ..\map256\ghz.bin FG Layout: ..\levels\ghz2.bin BG Layout: ..\levels\ghzbg.bin Objects: ..\objpos\ghz2.bin Palettes- Number of files: 2 Palette 1- Start index: 0 Number of entries: 16 File: ..\pallet\sonic2.bin Palette 2- Start index: 16 Number of entries: 48 File: ..\pallet\ghz2.bin Angle Array: ..\collide\anglemap.bin Collision Array: ..\collide\carray_n.bin Rotated Collision Array: ..\collide\carray_r.bin Collision Index 1: ..\collide\ghz.bin -EOF-Pay no attention to "..\pallet\sonic2.bin", as in my hack, Sonic's palette is also loaded dynamically, and that isn't part of this guide. But see how under "Palette 2-" the file it loads is "..\pallet\ghz2.bin"? That's what your GHZ2.sep file should have. Yeah, I'm explaining myself again, but whatever. Modify a few palettes in GHZ2 as a test, and save the changes.
Then, build your ROM and test. If you run into errors, you obviously made a mistake and forgot to do something. However, assuming you followed the guide properly, you should have dynamic zone palettes. Congratulations. You ownz!
