Earlier this week, I worked through the sound and music demos and, on Friday night, I started work on the first example game in the book, "Game of Ball". I finished this Saturday evening. There's a glitch sometimes where the ball gets stuck at the bottom of the playfield, maybe I messed up something in the collision codes, I'm not sure. I've included the .bin. Other than typing the code myself, this is obviously NOT my work, but that of the original author, Oscar Toledo G!
