Prince of Persia: The Sands of Time Unlockables
Unlock Prince of Persia 1
After you get your new sword, (the first one you can break walls with), continue on your merry way out of the baths, the next area will be a massive open cavern like area, full of jumping navigation puzzles, after that room, there is a small room with one of those turny switches, turn it so it's 180 degrees from the way you entered, now both doors should be closed. Run up to the wall that the switch is facing, and break open the wall, you should receive a message that says "Prince of Persia 1 is now unlocked". Select 'ok', and you've done it. Continue to walk forward, towards the stair case that you'll see, and it will let you save your game, then ask you if you want to continue going that way and play the original Prince of Persia. If you want to continue playing Sands of Time, select no, and you can go back and play the original in the Extras menu of the main game menu.

Unlock Original Prince of Persia
You'll need to start from the Above the Baths save, once you have your new sword. Go down the stairwell that leads to a large cavernous area. After you make it through this area, you'll end up in a small room with Farah. There's a lever and gear in the center of the room. Turn it clockwise until it clicks twice. Both doors in the room are now closed, but you have also opened a secret door that you cannot see. Go to the wall directly opposite the entrance. Swing until you find a spot on the wall where your sword doesn't spark. Strike this area a few times to reveal a hidden room. Enter to unlock the game, which is now available from the main menu.
