This theme should be the RetroPie default. Very good work.
Can you add Game & Watch to the list please ? It’s very polished emulation.
also ResidualVM (although I haven’t managed to get any of the 3 games to work on RetroPie, it just exits back to EmulationStation, they work on the PC version).
And possibly Daphne just because it’s missing, I tried Dragon’s Lair and it didn’t look very smooth on Pi2 (might be because I used the M-HD version), and Space Ace Enhanced didn’t work.
