I think I may be at a disadvantage. As shown in the pics, this is the rig I am using for the GOTM comps. It is running Attract Mode operating system, but I can't figure out how to change the ROM settings ex) lives, difficulty, etc.. Anybody have any ideas? I'm new to the RetroPie and any help would be greatly appreciated. I have attached the menu I get when I launch the ROM, but when I enter the Edit Custom Config, it is blank. Should I be running the ROM in Emulation Station?
