Hey Brad,
i already watched some of them. But to be honest, i hate video tutorials :D Always have to watch a 20-30 minutes video with alot of already known or repeating stuff. Don't get me wrong, you make great tutorials. But I prefer written tutorials, just couldn't find any good one for retroarch yet.
My only problem now is that i can't change the size of the game. Already tried to turn on integer scaling and changed the video scale, but it just doesn't change anything...
EDIT: I figured it out, i had to do it with the shaders instead of looking for a game resolution option
