I was playing Astroshoot and I was thinking that the hit detection between player0 and player1 was off, so I looked at the code and realized that I didn't check for a collision right after player0 moved to the right or left (in essence while player0 was moving left or right into a rock.) So I changed that and added some playfield colors. And yes, I know that there's already an Astrosmash version for the 2600, I just wanted to make something like that.
