The second half of my test run of the original Prince of Persia (v1.4). Recorded one level at a time in DOSBox.

Part 1: http://youtube.com/watch?v=ZvlNppHraWs

Segments:
Level 8: 1:46.23
Level 9: 2:08.93
Level 10: 1:02.17
Level 11: 1:10.76
Level 12a: 1:18.78
Level 12b: 0:23.20
Total Time: 14:16.44
Time Spare: 45:43.56

Note: I call this a 'test run' because I was planning on later doing an unsegmented run under a pure DOS setup.

I didn't have much motivation to follow up on that though, partially because DOS is a complete pain in the arse to get working these days, so it got put aside.
