I didn't notice that there was a dpad icon in the retropad editor(sorry for that). This commit uses that icon instead of the icon I created. Now it looks more better.
I noticed that some icons in the old layout(analog icon, dpad icon, and the c buttons) were a bit small. Hence, though they were playable in portrait mode but it was difficult in landscape mode. I increased the icon sizes. Now it should be easier to play games.
Looks like we have some merge conflicts here. You probably need to update your branch to include your previous submission (note: this is just for reference; you can do it in your own repo's main page):
