The default to save or load a game in mame is F7 and Shift F7. I changed this so I could use my joystick/buttons. But after you initiate a save or load you then have to "select position to load/save from" but then I have to use a number key from the keyboard, which kind of defeats the purpose of using the joystick/buttons to save/load.
Is there a way to "select position to load/save from" using the joystick/buttons?
