I am currently trying to reverse engineer some game files. I have found the exact location of each graphic element, but now I am stuck trying to convert their data to "readable" rgb code. They use 16 bit long Hex values (0xC306 or 110000110000 converts to R:0 G:219 B:24)
The file is written in little endian. Could someone tell me how they convert it?
More examples:
(0xCFC0 -> RGB 198 24 123)
(0xFFF0 -> RGB 247 28 255)
(0xFF00 -> RGB 0 28 255)
It appears to be stored in byte-reversed order from what you gave with a standard 5-6-5 bit encoding and then scaled to a maximum of 255 for each.
R: 24 (0b11000) * 255/31 = 197 G: 6 (0b000110) * 255/63 = 24 B: 15 (0b01111) * 255/31 = 123
R: 30 (0b11110) * 255/31 = 247 G: 7 (0b000111) * 255/63 = 28 B: 31 (0b11111) * 255/31 = 255
R: 0 (0b00000) * 255/31 = 0 G: 7 (0b000111) * 255/63 = 28 B: 31 (0b11111) * 255/31 = 255
