I know this game but while recording in my current PC the SDLPoP version runs smoother than the DOSBOX version. can some experient player tell me and then close the thread?

Hi, Currently only version 1.4 is allowed for DOS categories, and the only emulator allowed is DOSBox 0.74-3. The in-game timer script is designed to work with this specific setup, and it also makes it hard to cheat since it doesn't have readily available input recording. Furthermore, as smooth and faithful SDLPoP is, it does have some minor inaccuracies from the original DOS version of the game, especially when it comes to how it handles bugs. For speedruns, it's critical that the bugs work exactly as it is in the original version of the game.

I would add that, if you have any issue with DosBox, record a video and join the Discord! I'm sure someone will be able to help you if anything abnormal is detected while watching the video :)

To be precise about it, SDLPoP is a Windows port of Prince of Persia and as though it replicates the DOS port, it can be considered as a separate version. As such, if we would allow speedrunning it, it would be in a specific category. But since the gameplay is exactly the same as on DOS, it wouldn't be very appealing.

ok, I can manage to run on DOS, the only issue will be The Slown down that exists, the game runs like 10% slower than sdlpop. I hope this not affects IGT

Yep it does not, IGT is pretty consistent across machines. Also if you are feeling the game is running too slow, make sure to set the correct cycle count in the DOSBox settings.
