I developed a simply Python console program just to select and execute mame roms. Both using call method or Popen method from subprocess library, there is no problem executing mame4all, so it returns to main program keeping the screen content. But when it calls advmame software, when it returns, the screen content of my console program apears partially drawed, with multiple black sections, and no refresh properly. It seems that advmenu software changes the screen mode, and after that, the screen works bad. It's a way to call advmenu and returns to my original console program aspect?
