Add white and black to palette files with fewer than 4 colors.
|
|
|
|
Pokemon Crystal only defines two colors for a pic palette to
|
|
save space, filling in black/white at runtime.
|
|
Instead of managing palette files of varying length, black
|
|
and white are added to pic palettes and excluded from incbins.
