Hello,
I've had no luck getting GBC ROMs w/injected SGB borders to work in RetroPie. It doesn't even make it to the Nintendo boot screen, just immediately exits back to the menu. So I tested the same handful of GBC+SGB games in the Windows version of mGBA, and they all play just fine.
Is there any trick to getting these to work, or if not, might it be supported in the future?
