I did an analysis and write-up on the arcade version of Asteroids that goes into the details of the game design and physics: Asteroids: By the Numbers. I'm curious what people think about it, especially veterans of the game who are intimately familiar with the mechanics. I thought about going into collision probabilities and survival times against the aliens, but didn't know if there would be enough interest to warrant the time investment. Note that the numbers in the article are estimates based on screen measurements and weren't extracted from the code.
This is an awesome paper on computational math http://www.jjj.de/fxt/fxtbook.pdf Matters Computational Ideas, Algorithms, Source Code In depth explanations of various computational and math techniques, tricks, and gotchas. The first section deals with integers and binary and is totally relevant to 6502 programming. It's a great reference, getting into details of various math operations with an eye on pitfalls and optimization. ( Thinking of you [and DiMath] when I posted this Selgus! )
So, I know that the main CPU runs at 1.19 Mhz, and I also know that the TIA is 3 times as fast as the 6507, so it runs at 3.57 Mhz. How would I figure out how long a single color clock takes to execute?
