aetsby_patcher.c:
/*
* quick binary-patching code - this code is able to patch AND *unpatch* a
* desired binary file, when given the proper patching information.
*
* you'll need to make a list of each byte that you want modified, in
* the format specified below (a nx3 array), where n bytes will be changed.
* unix's cmp, or windows' comp.exe are two examples of p
rograms that should
* be able to do this for you. you'll also need the exact filename, and
file
* size in bytes.
*
* now, fill in your custom patch information below.

NOCD Crack for X-Plane 700 RC4, by aEtSbY
FILENAME "X-Plane 700.exe"
FILESIZE 2397696
Just run the patcher exe in x-plane's "main" folder - the
one that includes
the above FILENAME. If you'd like to undo the changes, repeat the above
operation.
Sourcecode for the patcher is included - and is easily customizable ;)
Enjoy life!
