Introduction

Another entry on my quest to TASing every port of Prince of Persia (cough Myst cough). For this one I chose the european version of the game which contains three crucial differences:

While the USA version contains all 14 levels present in the original game, the european one contains 4 extra levels (18 in total). This version is therefore more complete than the former.

Although the PAL version runs at a lower FPS (50), it plays one game frame every 4 emulation frames. The USA version runs at 60 FPS, but plays one frame every 5 emulation frames. The effective in-game FPS is therefore faster for the Euro (12.5) compared to the USA one (12).

On level 1, the kid starts on a standing position in the USA version (faster) while, in the Euro version, he properly falls from the door.

Comparison Movie

This movie completes every single one of the 14 original levels faster than the current publication (1193M (TASVideos)). The addition of the 4 new levels is what eventually makes slower time-wise. See the movie below for a clearer side-by-side comparison

Strategy

Basically gates don't exist.

Also, when the level exit door is open, you can leave the level using the level entry door, even if it looks closed. I discovered this by accident thanks to the bot, who just found this while exploring less optimal routes. This is only applicable on the new levels as, in all the original levels, the trigger that opens the exit door is always closer to the proper exit door than to the entry door.
