Some gbc games don't display properly in sgb mode

[pokemonfan6498]

i was trying to play Marie no atelier gb and noticed that for some reason it doesn't display graphics besides black screen and border but music was present so that's a sign that it works but doesn't display graphics for some reason

In Marie no Atelier, the palette isn't being set in either SGB or SGB+CGB mode, it's taking on whatever is set as the GameBoy Palette(if Bios is allowed to run) for part of the Obj palette, and nothing at all for the BG palette. Nothing for either if the bios is skipped.

Inversely , some games display the CGB image but get the mgba border instead of the SGB border (Links Awakening, Pokemon)

I suspect this is a duplicate of #3000
