I may be remembering this wrong, but back in the day, couldnt you hit R shoulder to make a GBC or GB game fill the screen on the GBA? I'm asking this because I cant seem to make Pokemon Red or Silver fill the screen correctly when using Goomba to emulate them.
Is it possible to make the games fill the screen correctly? I tried turning off the border, but its obviously kind of derped.
