Editing the GameBoy Virtual Console Palette
How to Change the GB VC Palette to the Original
It's one of those things that leaves me scratching my head: "Why the hell didn't Nintendo take the time to perfect the color palettes of the GameBoy VC releases?" Instead, we got eye-bleeding pukotron green. So I changed the palette to be more like the original. It's pretty easy and straightforward. Well, here we go.

What To Do
Step One - ROMFS
What To Do
Step One - ROMFS
First, you need to get access to a GB VC rom's ROMFS contents using the rom editor. If you don't know how or you need the tools:
Google: "[TUTORIAL] - Convert GameBoy(GB) ROMs to GB VC 3DS and CIA files" (including the quotation marks).
Click on the first link.
Click on thread # 118 "[TUTORIAL] - Convert GameBoy(GB) ROMs to GB VC 3DS and CIA files".
Download the tool pack.
Follow the tutorial on that page after you're done with this one; the tool pack contains the injector, ROMFS contents, and the .3ds rom.

Step Two - Config.ini
Once you have the ROMFS contents, open the "Config.ini" file in Notepad.
The part we are gonna edit is right at the top of the file.
Change:
Code:
Color0 = c23,31,4
Color1 = c19,29,5
Color2 = c11,17,8
Color3 = c9,9,9
ColorLCD = c20,27,7To:
Code:
Color0 = c27,31,25
Color1 = c14,23,11
Color2 = c4,11,8
Color3 = c0,2,3
ColorLCD = c17,29,13It should now look like this:
Type: [ctrl]+S to save.
...And that's that. You now have the config.ini to put into a GB VC rom for an old school GB experience. If your using the ini and injector tool from that site, the ini will be applied to all subsequently injected roms.

Using Different Palettes
To use different colors or to have a custom ini for each game, you need the RGB values for each desired color, plus the LCD. The RGB values on image-editing software is typically 8-bit (0-255), but the ini uses 5-bit RBG (0-31). Once you have the 8-bit RGB values of your colors selected, we need to convert them to 5-bit values. To do this:Using Different Palettes
Code:
(a*31)/255=b
where:
a is the 8-bit value
and
b is the 5-bit value (the number to type into the ini)
Example:
8-bit value: 78
(78*31)/255=9.487
5-bit value: 9Remember, you need to do this for each R, G and B, for each color (0,1,2,3, and the LCD color). That's a total of 15 values!
0,1,2, and 3 are the four colors of the GB palette from lightest to darkest, and the LCD is the color shown between frames (e.i. between the start-menu and main game-room). That's all there is to that.
So say goodbye to puke-green GB games and hello to infinite custom color possibilities.
Have fun and thanks for reading my first ever web-tut'!
