GBC LCD colors: (on) make GBC colors look as on real GBC. disable to use RGB values directly without conversion.

…that would lead to the question of which type of screenshot is "correct". Since people may use different emulators (VBA & VBA-M use the raw RGB values by default, BGB uses the real GBC colors by default, Gambatte by default looks different than all three, etc.), it's important that the desired look is established.

Don't forget that people will also be doing these glitches on the actual hardware as well- not all of us are emulating.

Personally, I say that the "real GBC" option is best, as it's what the actual hardware uses, and thus is the option that has the most claim to being "correct". But that's just me.

Personally I would say that just because the real hardware displays washed out colours doesn't mean it's "correct", it's just accurate to the real hardware, which is "incorrect". Consider that IIRC Super Game Boy and Pokemon Stadium's GB Tower don't have washed out colours, unless I'm wrong, in which case disregard everything I just said.

Even though GBA is described to be compatible to CGB games, most CGB games are completely unplayable on GBAs because most colors are invisible (black). Of course, colors such like Black and White will appear the same on both CGB and GBA, but medium intensities are arranged completely different.
Intensities in range 00h..0Fh are invisible/black (unless eventually under best sunlight circumstances, and when gazing at the screen under obscure viewing angles), unfortunately, these intensities are regulary used by most existing CGB games for medium and darker colors.
Newer CGB games may avoid this effect by changing palette data when detecting GBA hardware. A relative simple method would be using the formula GBA=CGB/2+10h for each R,G,B intensity, probably the result won't be perfect, and (once colors became visible) it may turn out that the color mixing is different also, anyways, it'd be still ways better than no conversion.
Asides, this translation method should have been VERY easy to implement in GBA hardware directly, even though Nintendo obviously failed to do so. How did they say, This seal is your assurance for excellence in workmanship and so on?

The backlit GBA SP (model AGS-101) also displays bright colors. The washed-out colors are only a limitation of the frontlit LCDs used in the earlier systems.

As far as Im aware, Nintendo has never used any color correction for GBC games, even for the Virtual Console. But if they have, that would be interesting and more convincing than whatever BGB does.

Oops, looks like you messed up the quote there.

Thanks for telling me! I got rid of there being a second copy of the pictures now.

If it's not too trouble, can somebody use a camera to take a both a GBA AGS-001 and GBA AGS-101 screenshot of that spot in Pokémon Crystal please?

Here's the equivalent of the OP pic in Gambatte. Enabling "GBA CGB Mode" doesn't seem to affect the outcome in Pokémon Crystal.
