This version of Penetrator was almost "for free" once I made the Plus4 version of the game.
I had some trouble coming to grips with doing audio on the C64 and even though I managed it technically, it will be clear that doing audio is not my forte. I guess this is passable, but not great.
The joystick, if used, goes in Port 2. I made this version, just like the Plus4 version, bomb and shoot both on the one Joystick button. I also made the key to the right of p, or the key to the left of q be the fire button (hopefully works for both left- and right-handed people). The ZX Spectrum game used the forward button also as the shoot button (short press vs hold). That made the game way harder to play but since I am now old with slow reflexes, I need all the help I can get.

PS. The high-score save routine appears to only save the 1st time and throw an error after that. I have not yet figured out why this happens.
