GameBoy/VirtualBoy Palette

[Deathbringer]

Does any emulator do the alternate Super Gameboy/Gameboy Color palettes? One of the palettes there (Left+B I think) is probably as close to the grayscale as we could get. And I think another did the greenscale from the original Gameboy too.

EDIT:

I found a version of VBA that actually lets me do the BIOS screen. The hex for the Left+B palette is:
White #F8F8F8
Light Gray #A0A0A0
Dark Gray #505050
Black #000000
