The game that launched a multi-billion dollar franchise is now laid bare for your hacking pleasure. [Jordan Mechner] just posted the once-lost source code for Prince of Persia. This game was ground-breaking for its use of rotoscoping to mimic the movements of an actor (in this case it was his younger brother). Oh, and it’s a ton of fun to play.

This comes at an appropriate time since yesterday was the the 35th anniversary of the Apple II release. PoP was written for that platform but should be easy to get running on an emulator if you’re just interested in cloning the repository so that you can play it through once again. Interestingly enough, the source code went missing for many years. [Jordan’s] been looking for the original source code for a decade. Turns out his Dad came across a cardboard box with some original copies of the game in it and shipped it off for [Jordan] to take care of. Inside was a set of 3.5″ disks that are pure retro gold.

So here’s your chance to inject yourself into the game. The question is, will you be the Prince or will you be Jaffar?
