IPS PATCHER v1.2

                                Amiga version

                          Coding by ARaGoRN/ViSION


When you start the program a window will open with 3 gadgets in it:

PATCH GAME FILE
~~~~~~~~~~~~~~~
   Use this to patch a game. You are asked to select 2 files. The first
   file is the game file which is to be patched, the second file is the
   patcher file.

CREATE PATCH FILE
~~~~~~~~~~~~~~~~~
   Use this to create a patch file. You are askes to select 3 files:
   The first file is the original, not patched file, the second file is
   the patched game file and the third file is the patch file you want 
   to create

QUIT
~~~~
   Guess what? This quits the program... 


Note: This program needs the reqtools.library! Make sure it is installed
~~~~~ in your libs: directory.


Bugs!?

If you find one, please report it to me (Aragorn/Vision) at my bbs:

IPS File format
~~~~~~~~~~~~~~~
Some guys asked me to explain the IPS file format. Here it is:

"PATCH"        ;5 ascii bytes for id purpose.

Then, as often as needed:

$123456        ;3 binary bytes: 24 bit address calculated from start.
$3456          ;2 binary bytes: number of bytes to copy/replace (range 1-FFFF)
$AABBCCDDEE... ;these are the replacement bytes ($3456 bytes in total)

or

$123456        ;address as above
$0000          ;size 0 is a special case: Block fill
$3456          ;number of repeating bytes (range 1-FFFF)
$AA            ;This byte is repeated $3456 times

And at the end of the file:

"EOF"          ;3 ascii bytes end-of-file.


Updates
~~~~~~~
v1.1:

A little imcompatibilty between the PC and AMIGA version caused the
file length of the patched file to be wrong. Somebody changed the patcher
specs and the PC version did not write an end marker and the AMIGA version
did expect one, so it gave an error and the last couple of bytes of the
patch were not copied. Fixed now. (Thanx to Papillon for telling me about
this problem)

v1.2:

Fixed the filesize problem with patches created with this amiga version.
Also changed the *.IPS into #?.IPS
