SOLDIERX.COM Nobody Can Stop Information Insemination

file patcher available with both GUI (on Windows) and command-line mode plus various features. It uses some text files with the lpatch extension for the list of operations to perform on the target file to patch.These text files are trivial to create and edit and allow to specify comments, the default name of the file to patch, an introduction to display before apply the patch, MD5 hash verification, the modification of a byte at a specific offset, the substitution of a sequence of bytes or a string, wildcards and more.Exists also an older version of "patch files" used for substituting bytes at fixed offsets and are identified by the lpatch.dat name.On Windows the tool can also be used to patch a running process and launching+patching it.
this patcher and its patch files are the only that I use for my patches.
