devhammer 3:2f09c90a732d 1 // Updated version of the official firmware for the Outrageous Circuits RETRO
devhammer 3:2f09c90a732d 2 // Modified by G. Andrew Duthie (devhammer)
devhammer 3:2f09c90a732d 3 // Changes:
devhammer 3:2f09c90a732d 4 // - Added sounds for all ball bounces
devhammer 3:2f09c90a732d 5 // - Changed ball from square to circle
devhammer 3:2f09c90a732d 6 // - Adjusted collision detection to add ball speed every 10 paddle hits
devhammer 3:2f09c90a732d 7 // - Added scoring
devhammer 3:2f09c90a732d 8 // - Added mute function (not fully implemented...needs to be set up on a button).
loop 7:c0f12f624832 9 // Further mods buy loop (loop23)
