Could you please include a CMJ file for C64Mini users so that they don't have to use the on-screen keyboard
I made one for one game and keep copy and pasting it and renaming it for each game I add. Once you got one set up you can keep reusing it, just rename it.
That's fine if the keyboard mapping is the same for every game to the joystick. For instance, you can map commonly used keys to the 2nd fire button and other buttons on TheC64 joystick, especially important as the Mini doesn't have a working keyboard as standard.
