How do you do it. I beat the game in 11 hours. I read somewhere that you have to break some wall at 33%. That's a bunch of BS if it's true.
I've heard different answers & don't know which is right. Is it completing the game & then you can choose to play the full original PoP or just one level? Is it starting the game again & then reach a point to be able to play the level? I found this tip:
After you get your first new sword and cross the giant cavern. There is a lever you must move in front of a silver/white symbolled gate. Before moving that lever break the wall that is to the right of the symbolled door between the two pillars. You have revealed a gate move the lever to point at this gate to open it and go through it. You can now play Prince of Persia 1.
