So I'm following a tutorial to make a retro gaming console out of an old NES controller (e.g. http://www.instructables.com/id/RetroPie-Inside-an-NES-Controller/). I have the controller already configured and set up correctly. To configure the controller I need to go through a BIOS program to select some options then add some text to a file.
Rather than repeat these steps whenever I want to configure a controller, is there a way to write a script to do this? I can write a script to add text to the file no problem but
my question is can you write a script to open BIOS and select specific options from the menus within?
