Submission #7134: eien86's DOS Prince of Persia in 13:08.53

[TAS] Prince of Persia (DOS, 1990) any% by eien86 in 12:10.000

In this timeless classic, the tyrant Jaffar has seized power and has forced Sultan's daughter to marry him. You, the brave youth who is a prisoner in Jaffar's dungeons must rescue her within 60 minutes. Little does poor Jaffar know that he will be defeated in a fifth of the intended time.

The objective of the game is to beat all 14 levels in less than 60 minutes (IGT). In the "any%" category, all tricks and glitches are allowed except for the use of cheats. This category requires that all levels are completed (without skipping the first three levels using the SHIFT+L cheat code). This run includes the copy protection level, present in the unaltered copies of the game.

This movie makes the best effort to reduce the real time to solution. However, it is the IGT the one used as the metric for speed, as it omits cutscenes and account for changes in framerate (the game operates in 12 FPS normally, but 10 FPS during combat). The IGT starts immediately on Level 1 and stops as soon as Jaffar dies in Level 13, as this is the time taken for the high-score board. Level 14 is only accounted for in RT, hence the difference between both times.

A rough estimate IGT for the level skip (cheat) category can be obtained by subtracting the time for the first 3 levels. In this case, it results in 08:58.666ms. This represents a notable improvement compared to 12:20.58 of the previous level-skip TAS produced by David Newton (https://www.youtube.com/watch?v=hfOocUkxJ08).

In general, this run abides by the same rules as the RTA runs (https://www.speedrun.com/pop1). Only difference is that we use the Prince of Persia 1.0 version as emulation for newer versions does not handle sounds well. Here some guard reaction times and probabilities are changed, but overall the gameplay is the same.

This movie is the result of decades of routing and discoveries, and has been developed with extensive help from the current speedrunner community. Notable contributors to the routing are the actual game top speedrunners, such as (in no particular order) crem, CapnClever, 7eraser7, Karlgamer, YOLO4GG, GoodSpectre, Higlak, Velcheran, Creditor, WinterThunder, uvq3tsa, Wolfadawn, KenshinTrek, and GMP.

The route has improved a great deal during the last few years thanks to the use of savestate-enabled emulators (e.g., DosBox-X), allowing players to try different tricks without losing too much time. The development of this TAS is largely based on the existing route but has introduced two novel approaches:

Thanks to the use of emulators (JPC-RR) and memory debuggers (Cheat Engine), the discovery new tricks (e.g., level 4, 7 and 8 skips -- https://www.youtube.com/watch?v=gA8OhqKGfoI, https://www.youtube.com/watch?v=EtFVLF5kuds, https://www.youtube.com/watch?v=MlBbu612T1o) that would have not been otherwise possible, as their discovery required a frame-perfect input and RNG-heavy setups. Fortunately, more human-friendly versions of these skips have been developed after their discovery.

The development of an open-source version of the game (SDLPop, https://github.com/NagyD/SDLPoP) allowed the development of a high-performance parallel breadth-first search bot, called Jaffar (https://github.com/SergioMartin86/jaffar) that exhaustively explores all possible movements in each possible frame. The search is made possible by constraining the exploration space to that of a pre-determined route, requiring a few trillion states per level. As a result, the bot found the most efficient way to traverse the community-established route. We've applied Jaffar repeatedly on a supercomputer to solve for every level. Following strict definitions, the re-Record count is: 817,608,423,040

This run is 100% reproducible with the sequence of steps shown below (. = nothing, S = Shift, U = Up Arrow, D = Down Arrow, R = Right Arrow, L = Left Arrow), and the following initial RNG state: 0x4B43826D.

The route for this level has been proven to be optimal by the bot on sheer brute force. The strat includes bunny hopping at the beginning for a quick fall and then skip the guard via a timed jump.

This level appears in the original copy of the game, and is meant as a copy-protection mechanism. As can be seen in this TAS, it does not do quite a good job since the solution is determined by RNG at the start of the game. Only 14 different possibilities exist, so that it would take a few attempts at drinking the first potion to get past it. In this TAS, I was very lucky and got it in the very first attempt, lol!

A long level. No changes to the route here compared to RTA, but a lot of RNG optimization by the bot to skip all guards faster.

The bot-optimized movement here played a big role in shaving those last few frames. Movement, especially while ascending/descending the way to the exit door open tile has been highly optimized. An RNG-induced hit by the skeleton saves a few backward steps with the sword.

This is one the most abused levels in the run. First, we trigger the guard into opening the door for us, skipping half of the level. Then we manipulate the next guard into helping us open the exit door faster. This includes double-moonwalking him and then teleporting him into the mirror room, where he will vanish from existence when the shadow appears.

Here the door skip is employed to skip a big part of the level. This is performed by luring the guard to the left and then clipping through the door while on-guard. The rest of the level includes the normal route, optimized via the bot. At the end, we use the guard to help us glitch-activate the exit door open trigger prematurely, which is why it is already open when we enter the last room. This strat does not save any time but provides entertainment value.

Perhaps the most broken of all levels, we employed the newly discovered level 7 skip which contains a whole array of glitches all working in unison. First, we 'moonwalk' the guard through the chomper, then we make him fall 2 stories without dying by exiting and reentering the room. Then we use the guard to perform a 'Yolo skip' through the door. This route was exhaustively optimized by the bot.

Another spectacularly broken level. We lure the guard towards the 'useless' bad potion room and use him to make us clip through the wall and the floor towards the end of the level. This marks the return of the mouse who comes to save the day.

Definitely the longest and hardest to crack level. Here, the only skip found was the damage clip through the last door that allows us to skip making the loose tile fall, saving a few seconds. Other than that, it is still ripe for skips. Here the movements were highly optimized by the bot.

Here we make use of a few tricks, including 'guard jump', 'overflow teleport', 'yolo skip', 'fall damage cancel', and RNG manip. It would be very hard to improve this level any further.

This level remains skipless, mainly because of it's layout (all horizontal) it is still hard to crack. However, all moments were optimized by the bot, shaving many frames in the way. A new alternative ending was found in which the guard opens the exit door for us. This new strat does not save any time but provides entertainment value.

A climbing level, here we use the 'overflow teleport' trick to skip to the shadow screen. Here, we grab the sword and immediately merge with the shadow to exit the level.

Here we used the bot to manipulate RNG to guarantee a fast Jaffar kill. As soon as Jaffar dies, the IGT clock stops.

This level only requires running a few screens, and IGT does not count anymore.

This TAS is 27 seconds faster than the current RTA WR, and 9 seconds faster than the sum of human best segments. This speaks to the incredible skills of the RTA runners, who have incorporated most of these seemingly TAS-only tricks into their runs succesfully.

Nach: Note: To play back this movie, the single disk floppy version needs its file contents copied verbatim into the root of a hard disk image. Installing the game to a hard disk and taking an image of that will not produce a matching hard disk image.

Nach: This run is quite nice. Exploiting various wrap-around glitches and guard mechanics was a beauty to behold. Feedback is positive as well. Accepting to Moons.
