ok, so i have this nexus bmp (in my sig, without the creep)
When I compile in RetroGRP, the colors screw up (i have rle encoding)
so i went into photoshop and i went to color table and chose the windows palette, and my nexus had screwed up colors like when I compiled with retrogrp.
so would there be any way to use that palette but not mess up my nexus' colors?
anyways, i'm not sure about much, since i'm pretty clueless when it comes to grp editing

You have to load the units pallete not the windows pallete.
GRPs have to be 256 color 8 bit bitmap. with the sc pallete applied to them.
To get the unit pallete just open an extracted frame in PS change mode to index with exact colors and save that color pallete.
Then load it up on anything and you should be good.

try resetting locations on retro grp, alot of times that fixes my pallet mess ups.

actually, it was because retrogrp only compiles bmps in rgb mode (i was in indexed)
