Patcher2

Small C# binary file patcher utility.<br> The interesting bit is the byte pattern based search and replace.<br> Should handle file sizes up to 2GB, and is really fast.<br> (A lot less fast, while making patch patterns, and only handles files of a few hundred megabytes.)<br> (Created for educational porpoises.)

Notes:

Pattern format is like in 010 Editor, but Cheat Engine AOBScan format is also accepted.<br> Replace is also a pattern, like search.<br> Offset means the offset compared to the beginning location, of where the pattern is found.<br> Offset can be negative, and is in base 10, while the patterns are in base 16.

Extra (hidden) features:

Has experimental, memory based pattern replace feature.<br> Compile for 64 bits, and it will work with 64 bit processes.<br> (Can also patch itself to 64 bit. Just run self_to_64.bat in the Release directory. :) )<br> Writing "proc:" in to the file field, will bring up the process list window.<br> Leaving the replace field empty, will allow you to use the Locate feature.

BeaEngineCS optional extension project is:

Based on:

PE file header stuff: http://sandsprite.com/CodeStuff/PEOFFSETCALC.cs<br> BeaEngineCS: https://github.com/carterjones/beaengine-cs

Using:

BeaEngine: disassembler library for x86 x86-64 (IA32 and Intel64)<br> http://www.beaengine.org/

Notes:

Have BeaEngineCS(64).dll (and BeaEngineCheetah(64).dll as well of course) in the folder, to use it's disassembly based address masking features, when creating a difference based patch with the "m" command line option. It will make the process MUCH slower.
