I rarely take the time to read through long threads but this one I absolutely did. What an incredible machine. So well thought out, some new innovative shots too. I can't imagine spending 5 years on one project - truly a labor of love! I also love the fact you implemented 3 flippers. You obviously keep fine tuning the code which shows your passion. The only thing that annoys me with homebrew games is repetitive sound clips used for common shots. Is there any way to alternate "some" of the shot audio clips? For instance a spinner can be programmed to make certain noises depending upon what mode you're in?
Anyway, again thank you for sharing with us, this machine is just absolutely incredible. This is by far my favorite homebrew game.
