This is an issue i found when implementing the NTSC filters. Currently when using palette presets,
no clour emphasis is seen on games that supports it. This is cause because the palette table is
fille with the same 64*3 colour info.
Using custom palette (palette file) and default both creates the emphasis as expected. So internally,
fceumm is able to support such feature.
The fix is to generate the base palette (64 * 3 with each triplet representing rgb colour), and then
send this internally using FCEUI_SetPaletteArray() to fill the colour table with emphasis instead.
- this implements blargg's nes ntsc filters using core options
- an optional height doubling is also added but disabled for performance reasons (might make that optional as a core option)
- since PS2 and PSP have their own blitter branches, these platforms do not have the ntsc filters since i dont have the means to test on those systems.
- compile with HAVE_NTSC=1 to have these options, HAVE_NTSC=0 disabled filter including core options
- HAVE_NTSC=1 is set as default, other than PS2 and PSP as stated above.
- This creates 2 new advance core options to minimize the number of core options shown
-- Advance System Options contains:
--- Overclock
--- RAM power on state
--- no-sprite limit
--- simultaneous opposing direction press
--- zapper crosshairs
-- Advance Sound Options contains:
--- Master volume
--- Sound quality
--- on/off for NES' 5-channel apu
- This also re-arranges the core options when advance options are shown, system options on top,
gfx/palette/geometry options next, input etc.
- ines.c - misc cleanups
- Fix Dendy not restored when changing overrides back to auto mode
- directly apply new scanlines and additional scanlines when changing overclock settings
- (readability) change variable name overlock_state to overclock_enabled
