Colour change in Pokemon blue

[KimiRaiki7]

In Pokémon Blue the color often changes briefly during battles (if sgb mode is enabled)
Is this a known problem?

No, I only noticed the problem in pokemon blue/red. Did you try it on your pocket?

I can confirm this behavior. If you compare to the spiritualized SGB core (or a physical SGB) this brief color cycle does not occur.

I noticed that on startup this core is using a green DMG-esque palette before flashing to black, the back to white with the expected SGB palette.

It seems that during any sprite palette swap (Pokémon red/blue does this when swapping Pokémon in battle on SGB so every Pokémon has an accurate palette) this core has a frame where both sprites default back to the dmg-esque palette. This is just my laymen's guess. This is also why the flash occurs when the health bar goes to yellow or red.

That’s odd… Any idea if it does it on mister?
