Banon Palette on SAve Screen

That $CAFDC8 offset is the NPC palette assignement, you will find it at $0AFDC8 in a hex editor. For the save screen, palette is part of OAM data, that has following format:

Code:

Byte 1    xxxxxxxx    x: X coordinate
Byte 2    yyyyyyyy    y: Y coordinate
Byte 3    cccccccc    c: starting character (tile) number    p: palette number
Byte 4    vhoopppc    v: vertical flip   h: horizontal flip  o: priority bits
          Note: the 'c' in byte 4 is the MOST significant bit in the 9-bit char #.

The data for Banon is at $D8EB73 ($18EB73):

Code:

02 (X coordinate)
80 (Y coordinate)
01 (starting tile 2?)
0C (00001100 -> 110 = 2 + 4 = palette 6)
