Fabien Sanglard's Website - Prince Of Persia Code Review: Part 1 (Introduction)
Even though it is the Apple II version written in 6502 assembly language, it was a pleasant experience to dive in the code of that mythical game: As usual there were many fascinating software wizardries to discover.
The Apple II apparent poor environment for game programming was actually ground to unmatched innovation and creativity : From self-modifying code, in-house bootloader, clever floppy disc format to skewing lookup tables: Prince Of Persia features engineering treasures in every modules.
Reading the source allowed me not only to learn about the game development process of the 80s but it also renewed my appreciation for things that we take for granted today.
As usual I took numerous notes that I have cleaned up on this page. I hope it will inspire others to read more source code and become better engineers.
Acknowledgment : I would like to thank Miles.J from 6502.org and Roland Gustafsson (author of RWTS18) for patiently sharing their knowledge with me.
