Thanks very much for linking to it. I was hoping to get the formula, not a program that does the convertion proccess but I see that the source code is in the rar package so I will definetly check it out when I am on my computer!

So a GBA color is stored in a 16-bit unsigned integer, with the first 15 bits being dedicated to storing color information (5 bits for red, green, and blue). This is called, obviously, 15-bit RGB.

To get an RGB color to a GBA color, just use this:

gba_color = (((red >> 3) & 31) | (((green >> 3) & 31) << 5) | (((blue >> 3) & 31) << 10))

To go from GBA to RGB, use this:

red = (gba_color & 31) << 3
green = ((gba_color >> 5) & 31) << 3
blue = ((gba_color >> 10) & 31) << 3

Hope that helps! :)

Haha I didn`t know you know that. If I knew you know that I would ask you before ^^

That is exactly what I was looking for.
