Patch Files
-----------
Patches file use the .PEH extension. This is where to store the starting time
and hit points. This helps to keep changes along with your mod. And they are 8K right now, (the program writes some unexpected bytes though).

Patch files are entirely different from DAT files. You just can't play a mod like typing PRINCE EXAMPLE.PEH,
it won't work! You need to load from PrinHackEd and write the changes.

How to read a patch file:
-------------------------
This will show how to do it in Pascal. (I'll let you to port it to C\C++).

Code: Select all

procedure LoadPatch (Filename : String);
var
PatchHandle : File;
begin
Assign(PatchHandle, Filename);
if IOResult = 0 then begin
BlockRead(PatchHandle, PatchVer, 1, PatchVer);
BlockRead(PatchHandle, Time, 2);
BlockRead(PatchHandle, HPLimit, 2);
BlockRead(PatchHandle, HP, 2);

end;

Installation

*READ THIS FIRST*

Copy PRINHACK.EXE to your Prince of Persia directory (whatever version you want).

Known Bugs
----------

- When you load the patches it reads them abnormally. When you wrote the changes,
it scrambles up the EXEs' varibles!
