384 colors displayed on 4 planes.

gfx1", 0, charlayout, 768, 16 ) /* colors 768-831 */ 64 colors
gfx2", 0, bg1_tilelayout, 256, 8 ) /* colors 256-383 */ 128 colors
gfx3", 0, spritelayout, 640, 8 ) /* colors 640-767 */ 128 colors
gfx4", 0, bg2_tilelayout, 0, 8 ) /* colors 0-127 */ 128 colors

looks like 128 colors per planes.

A true Beast!

A500 would have hard time to do that!
