Lives and score implemented. The one-digit number is the # of lives remaining. The four-digit number is the score. Because of this, I cannot implement the original scoring (if one was to shoot the Qotile in mid-air twice, the score would be 12,000 and therefore unable to be shown.) I wonder if there is a way to have one one-digit score and one six-digit score. Thanks for the compliments.

On that book Racing The Beam there's a chapter about Yars' Revenge and the neutral zone is covered there. It's not really about code there (in the book I mean), but the author goes more about how the idea was something new on those days.

OK, now all I need help with is how the qotile detects where you are, so where to strike. I'm using var27 and var28, but I don't know how to calculate their values correctly (correct being knowing where to strike.) These variables should be used between lines 182-191.

Latest version.
I think I got the qotile to get you decently. If not, let me know.
I also added a sound when you hit the orangish shield.

I've noticed that too, and it's a bug that I don't know how to squash.

Ok, I was just making sure it wasnt just my emulator.

How would I make it different colors like in the game?
EDIT : OK, figured it out.

How?

Worked on this a little more. I made the ufo faster and added a death sound, among other things.
