Use set_color_depth() here to set the color depth (8, 15, 16, 24, 32 bpp)

Is "board" defined ? shouldn't it be "thing" ?

You'll need to extract the palette from the image from within the grabber,
so you have a palette and a bitmap object.
You can then use something like this:

pal = (RGB*)data[THING_PAL].dat;
set_palette(pal);

thing = (RPG_SPRITE*)data[THING_TGA].dat;
