Sorry for resuming an old post, but creating new palette is still tricky for me (maybe one day someone will wrote a tool for helping in it!
They are 1K in size and contain 256 32 bit words with the RGB + mono values for each of 256 colours.
Each 32 bit word contains R (lsbyte), G, B + Mono (msbyte) with values 0-255 (Mono is used in mono / green / amber mode)
The 256 palette entries are indexed as follows (ms bit to ls bit):
M, R1, B2, G2, R2, B3, G3, R3
M is used for the menu overlay so the palette should be duplicated with M=0 and M=1
).The doubt is on the "M" used for overlay: i'm testing a palette for Sega Mark III, starting from SAM and EGA ones that looks similar, but i got a strange different behaviours while OnScreenMenu is on or off (or in the screenshoots) compared to normal use:
screnshot:
You can see the first two upper left green blocks are different in screetshooting and while menu on, and they are same color when exiting menu...
What i could have missed?
