 kungfum_pre_normalize.png is the palette fed to palette_normalize_range

 drivers that use palette_normalize_range: dkong.c, m62.c, mario.c, phoenix.c, popper.c.
IMHO visible degradation only in m62.c and phoenix.c

 for info: MESS also has a problem with palette_normalize_range: samcoupe is now only shades of grey instead of full colour. By replacing a few lines near the end of that routine with what used to be there, it can work again.

 btw It looks better if you remove palette_normalize_range from m62 and increase contrast to 1.5

adding some pics and info by Stefan Lindberg from this thread: http://www.mameworld.info/ubbthreads/showflat.php?Cat=6&Number=117256&page=&view=&sb=5&o=&vc=1
This confirms that at least kungfum colors are not supposed to be washed out. It's easy to tell on the red "thomas" text.

I'm disregarding the gfx artifacts here; lines like the kidniki hair sprite.
The resistors on the pic are the same as in video/m62.c, so that part is at least correct in mame.

 phoenix.c: it was a bug in the color prom resnet
m62.c: increased default contrast to fix it
