friend I have exactly the same doubt as you, because I tried in several ways at least increase the image of the logo of the systems but without success decrease I can now increase, something else and on the legal topics that we find on the net there is an example and the theme Snes MINI Classic that is beautiful and that in addition to existing ports is not even close to what is the original or the recalbox.
If you know anything, please let me know.
