Why don't they give options for NES emu controls? Like tilting Ipod/Iphone left, right, up, down emulates that why on the D-pad. Make it so the screen can be bigger, and buttons over lap the screen (Like GBA emu). Or swipe in a direction emulates that on the D-pad (Would be great for pacman) This would make alot of the games that aren't any fun at all to play totally playable. So why doesn't anyone do it?
