This thread is going to be about color edits for Neo Geo games you should feel free and share your edits. This thread will deal with the common neo geo palette system not Garou:MoTW(sorry it just ended up this way
Lets get started on what you need
First is a hex editor (any hex editor will do. I use Stirling or Hexplorer. Deadly Magneto aka 409 uses hex workshop)
Second is winkawaks http://cps2shock.retrogames.com/
(as it is the only emulator that does pictures unfiltered)
Third is this program Rgbw2n http://www.mediafire.com/file/d7z0z11ddsdwltu/RGB_W2N_eng.exe
For this tutorial I am going to use Kula's A color from Kof 2002.
Your First step into editing is to take a picture of the character you want to edit in game on Kawaks as a Unfiltered Screenshot.
Second is to open up your picture, rgbw2n, and a notepad(a real one or the program)
Now what you're going to do is turn on mouse tracker and get a gradient.
Best way to do this is to find something character specific.
Now look at the picture and the answer is pretty obvious its her jump suit.
Now get the colors from Lightest to Darkest(this is the most common gradient)
Which are 360B 1419 0466
Now we have to search for those colors in the file. In neo geo games there are files dedicated to palettes these are easy identfy they have p on the file name (example 066-p1.bin) there is usally 2 palette files in newer games since character rosters were getting bigger. Now back to kof 2002 since the roster 40 strong. I have a hunch that the bigger file has the character palettes so 265-p2.bin will have the palettes.
Now search 360b14190446 in the hex field of search you should come to location 9AB6C. This is just the jump suit ,but lets just jump to the conclusion all palette lines are 16 colors aka 32 bytes this is just for the main body no projectiles. The starting location of kula is 9AB64.
Now we're going into the color editing part. There is two ways to do this.
one is to drop the colors down to 256 and edit the picture color by color if your art editing program allows that.
Second is to edit the colors right there in the hex editor. Either way it takes time.
Here is the reason why to use Winkawaks
As you see the same picture produces different colors cause fba still takes pictures with the filter on there is no way to disable this.Also feel free to share your edits from your console versions (NGBC and ps2 ums) if able to do so.
