I'm enjoying the MiniCakeTV 32gb image. Have arcade controller paired up with an HDMI computer display. Trying to turn this into a dedicated vertical shooter system. Have used the HDMI rotate parameter in config.txt to get UI to rotate 90 degrees. Unfortunately, MiniCakeTV forces some kind of bezel on the UI while playing games. In this configuration, the bezel covers a few inches of the game screen on each side. Please see attached pic. I have renamed the mame directory in the overlays directory, but now a generic bezel / overlay is applied on every MAME game launched (as seen in attached pic). Any advice on how to disable all bezels would be much appreciated.
