#735 Deemphasis bit colors bug

[Cheater]

In current version of fceux - colors in pirate Aladdin game become more darker than in earlier builds. But if you use Prescale 2x (3x etc) filter - colors become normal. I try different builds of fceux that I have. So here is results:

In revision r3140 everything is fine.

In revision r3146 pause icon have weird green line, but games colors doesn't affected. If you use prescale filter weird colors of the pause icon dissapears.

In revision r3163 pause icon have weird green line and game colors are dark. If you use prescale filter weird colors of the pause icon dissapears and game colors becomes normal

Sorry for bad English. In all the examples I use the same palette, ofc

The darkened screenshot is operating correctly. The game applies deemph all over. That's what we were working on emulating during that time.
Actual bug 1. the scaled images arent applying deemph (could be fixed)
Actual bug 2. the gui (wont be fixed, because fceux is too much garbage to fix that part)

bug 1 fixed in r3226
