Prince Of Persia 3D:
To start the game at a specific level, make a shortcut
to the POP3D.EXE file and add one of the following to
the end of the string in the Target Properties box:

-l "geometry\rooms\prisonfix"
-l "geometry\rooms\ivorytwr"
-l "geometry\rooms\cistern"
-l "geometry\rooms\palace2"
-l "geometry\rooms\palace3"
-l "geometry\rooms\palace4"
-l "geometry\rooms\roof1"
-l "geometry\rooms\cityanddocks"
-l "geometry\rooms\dirig1a"
-l "geometry\rooms\dirig1b"
-l "geometry\rooms\dirig2"
-l "geometry\rooms\dirigfinale"
-l "geometry\rooms\ruins"
-l "geometry\rooms\cliffs"
-l "geometry\rooms\solar1"
-l "geometry\rooms\moontemple"
-l "geometry\rooms\finale"

Then start the game and select "New Game".
Note: Once this cheat is used, all subsequent
levels will have to be loaded this way because
this is overlaying level 1 and when the level is
completed, the game then automatically loads level
two instead of the level after the one initially loaded.
It does not work to save the game as soon as the level
loads, then exit the game and restart by not using the
cheat shortcut.

Save Game Hex Cheats:
Saved games are the files named SAVE001, SAVE002, SAVE003,
etc. in the directory the game was installed into (C:\POP3D,
for instance). Using a hex editor, the following game values
may be adjusted.

First search for the all lower-case word "buffer". It will be
at the end of a long string of paths containing the word geometry.
Now count 330 more bytes from the end of "buffer".
This location contains the amount of health the prince currently
has. The maximum value this may be set to is hex 76. Count four
more bytes and this location contains the maximum amount of health
the prince *may* have. This maximum value is also hex 76.

262 bytes past the end of "buffer" are the two bytes that enable
the three bladed weapons and six types of arrows. Hex 1F 1F
enables everything.

238 bytes from the end of "buffer" contains the number of
type 1 arrows the prince has. The maximum value this may be
set to is hex FF (255). The display for the number of arrows
will not show correctly on the game screen for values greater
than 99.

4 bytes further contains the value for type 2 arrows. Max is hex FF.
4 bytes further is type 3 arrows. Max is hex FF.
4 bytes further is type 4 arrows. Max is hex FF.
4 bytes further is type 5 arrows. Max is hex FF.
4 bytes further is type 6 arrows. Max is hex FF.

Sometimes the first of the six values for arrows starts
222 bytes past the end of "buffer" instead of 238 bytes
past "buffer". Then the type 2 arrows are at 238, type 3
four bytes from there, and so on.

Prince of Persia: The Sands of time:
Start the game using parammeter megahit x ( x is  a number betveen 2 and 14).
That`s how you will activate the cheats. Keys you may use to cheat while
playing- U (switch to a platform above), N (switch to a platform below),
H (switch to  the left platform), J (switch to the right platform), K
(kills all opponent players).
