Author's comments and explanations:
Another Prince of Persia version! This version was developed and published by Riverhillsoft in 1992.


Game objectives

  • Emulator used: Bizhawk 1.11.9

  • Aims for in-game time instead of real time

  • Takes damage to save time

  • Abuses programing errors in the game

  • Sega CD BIOS: us_scd1_9210.bin

Why choose Sega CD version?

  • Well, the gameplay's mechanics is the same of PC (DOS) version, which this version, includes several bugs that also works on Sega CD version. Also, this Sega CD version includes:
  • A more detailed intro, with cutscenes and voices.

  • In-game timer (as well as SNES version).

  • A speed adjustment option on gameplay and on battles (Normally, speed gameplay is 3 while speed battle is 4.)

  • A new Jaffar battle is included on that path where it should be that Princess's room.

Stage-by-Stage comments

General note: Almost all of the tricks/glitches used in this game requires a certain (and careful) position, in order to work these tricks/glitches.

  • Level 1 - No comments.

  • Level 2 - Thanks of a good pattern optimization of the fourth guard and a good pixel position, I did a extra jump to save time without wasting time to avoid the spike trap.

  • Level 3 - Getting hit on a skeleton saves a little time.

  • Level 4 - It's possible to force the guard to open the gate without needing to take the normal route, saving much time.

  • Level 5 - I attract the guard in order to abuse of a glitch to bypass a closed gate without to take a normal route, saving a lot of time.

  • Level 6 - Shortest level of this game! And skipping the boss.

  • Level 7 - A glitch is abused falling in a wall to skip some of this stage.

  • Level 8 - This level is much longer and much harder!

  • Level 9 - Longest level of this TAS. Since no have a escape on the room before the closed gate that leaves to the exit switch (and this exit button isn't next the gate), it's necessary to open the gate. I strike the first and last guard to avoid slowdown on the next rooms, respectively.

  • Level 10 - I kill the first and the third guard, in order to continue the stage and perform 2 glitches, respectively. The first glitch is grabbing on a ledge at the botton edge of the screen at the exact time when enter it. Using the glitch, I skip some parts and saving much time. This glitch works because the game assumes that you grabbed the ledge from the screen below and moves you up instead of down.

    The second glitch is bypassing a closed gate, which requires a falling floor and is necessary to kill the gurard. Oherwise, it fails.

    After the second glitch, I did a trick during the exit room to avoid the bounce amimation, saving time.

  • Level 11 - No comments.

  • Level 12 - Climbing down and back up again puts you a pixel further to the left, which is enough to let you safely knock the tile down, skipping some part of this stage.

    That glitch used after the first guard on Level 10 is used again to reach directly on the Prince's Reflection path! But, the reflection don't appear with a sword on this room (normally this sword disappear when reaches this path). So, I pick the sword, go to the next room and return to previous room, in order to appear the reflection. But, in this version, he's don't apeear correctly (due of this glitch). So, hitting him makes to appear correctly.

NOTE: On PC (DOS) version, the reflection, even with glitch, appear normally.

Reaching on the Boss (In this version, isn't Jaffar), I forced the Boss to go must next of the pit and striked to kill in one hit! After this, I reach the exit (this is the only door that it's possible to go to the stairs before opens fully).

Reaching on the final path, time for a final battle with Jaffar! Yes, this version has a final battle before reaches the princess.

Input ends before Prince did a final hit on Jaffar.

In-game timers

Special thanks

SprintGod, for the DOS's run, which helped me a lot. And includes several glitches that I used on my run.
feos: Accepting to Moons. This isn't obsoleting the Genesis version, despite of the latter being in Vault, because these games are actually not for the same platform, and for a cross-platform obsoletion, these are 2 different ports with different contents. This game features a different speed modes, and there is a faster one, but the one used here is default, and it's also the most true to the original, which is important for a Moons run.
