Yes me too, I don't care if the GUI is pretty, I am fine with the actual one, but would like to have an option to change keys like mame within the emulator, I heard that we need to configure the keys within the .gngeorc file inside conf folder inside neogeo folder but I change using 'ascii table values' and nothing happens. The main problem is screen size as you can see in the screenshots. Do you have it installed aswell?
