Summary	04242: All sets in m62.c and phoenix.c: Colors appears "washed out"
Description	Compared to previous screens as far back as I can test, the colors for all games in the driver all seem to suffer from colors that have faded or "washed out"
Steps To Reproduce
Additional Information	I'm setting to possible until such time we can be 100% certain this is not how they are supposed to be. r11392 is the offending revision - having to do with palette.c changes.

No.07258 hap Developer Feb 22, 2011, 21:16	kungfum_pre_normalize.png is the palette fed to palette_normalize_range
No.07259 hap Developer Feb 22, 2011, 21:19	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
No.07261 Robbbert Senior Tester Feb 23, 2011, 09:41	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.

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.
