+* Kizul's Definitive NES Palette.pal
+	For use with most games.
+	    If your emulator of choice is NEStopia (either the original, or the
+	"Undead Edition"), and you're attempting to play The Immortal, increase the
+	Brightness setting (Options > Video... > Brightness slider) to 0.31. Elsewise,
+	the game will be much too dark.
+
+	(Sadly, the Linux versions of NEStopia "Undead Edition" don't seem to have an
+	option for choosing a custom palette file.)
+
+* Kizul's Definitive NES Palette - for Bee 52.pal
+	For use primarily with Bee 52 (and other Camerica/Codemasters games).
+	    This palette changes the brightness of a specific palette index ($1D) to be
+	a little brighter than indices $xE and $xF, emulating the canon effect that Bee
+	52 exploits and allowing various background details in the game to show up
+	correctly.
+	    The canon brightness for all blacks (except $0D) is slightly-lighter-than-
+	pure-black (this palette uses RGB 20,20,20 for it); however, $0D is DARKER than
+	all of the other blacks, so when a CRT screen is filled with $0D, the CRT TV
+	will generally attempt to brighten the screen until the abundance of $0D matches
+	the brightness that the other blacks are normally, thus changing $0D from RGB
+	0,0,0 to RGB 20,20,20.
+	    This has an exploited side-effect of ALSO brightening the other blacks to a
+	shade of charcoal gray, though this trick is exploited exclusively (to the best
+	of my knowledge) by Bee 52 and The Immortal (The Immortal's title screen, that
+	is), and no other games.
+
+* Kizul's Definitive NES Palette - for The Immortal with Color Emphasis disabled.pal
+	For use exclusively with The Immortal, combined with the following Game Genie
+	codes:
+		GEOATSKV -- Color Emphasis (C.E.) disabled at Title screen, and
+			    during narration.
+		GPOEGSKN -- C.E. disabled in battles.
+		GPVEASKN -- C.E. disabled on Items menu, password screen, and
+			    conversations.
+		GOUEYNKN -- C.E. disabled while walking around.

+* Kizul's Definitive NTSC NES Master Palette - for Bee 52 and The Immortal.pal
+	For use primarily with Bee 52 (and other Camerica/Codemasters games).
+	    This palette changes the brightness of the palette indices $1D, $xE, and $xF,
+	emulating the effect that Bee 52 exploits and allowing various background details
+	in the game to show up correctly.
+	    The canon brightness for all blacks (except $0D) is slightly-lighter-than-
+	pure-black (this palette uses RGB 16,16,16 for it). Bee 52 uses $0D -- which is
+	effectively pure black -- for the outlines of sprites and for the main background
+	color in night-time levels.
+	On a CRT television, if most of the screen is filled with the $0D black, the TV
+	will usually try to brighten the screen until $0D is off-black. This brightening
+	causes the other colors -- the other off-blacks, in particular -- to become brighter
+	than normal, resulting in an extra shade of gray.
+	    This trick is exploited by Bee 52 and especially The Immortal. There may be
+	other NES games that use this trick, but I don't know of any others.
+
+* Kizul's Definitive NTSC NES Master Palette - for The Immortal (with Color Emphasis disabled).pal
+	For use exclusively with The Immortal, combined with the following Game Genie
+	codes:
+		GEOATSKV -- Color Emphasis (C.E.) disabled at Title screen, and

+		GPOEGSKN -- C.E. disabled in battles.

+
+	The Immortal uses a feature of the NES hardware called "Color Emphasis", which
+	can be used to tint most of the palette -- specifically the range of $x0 to $xD,
+	which includes the Whites, all of the colors, and the first column of blacks --
+	by dimming out unwanted shades. (If you set the Red C.E. bit to On, and the others
+	to be Off, the NES would output less Green and Blue in its video signal, making
+	the palette appear to be tinted red.)
+	    The Immortal, however, sets all three Color Emphasis bits to On, making the
+	52 affected colors dimmer than usual.
+	In addition, it also uses $0D (the darkest black) for the background color
+	everywhere, and it appears on the screen in large amounts -- which, on a CRT TV's
+	screen, makes $xE and $xF appear much brighter than usual.
+	    $1D (which is usually the same brightness as $xE and $xF) is affected by this
+	trick as well, but since it's also being affected by the Color Emphasis, it's
+	only very slightly brighter than normal.
+
+	You can also use the "~ for Bee 52" palette with The Immortal if your emulator
+	has settings for controlling the brightness. I use NEStopia, and have found that
+	increasing the brightness to 0.12 while using the "~ for Bee 52" palette is
+	very close to reality.
