Reverse Engineering

$5/hr Starting at $25

I have successfully analysed a number of programs, written with Borland and Microsoft compilers for both DOS and Windows, simply by debugging the final executable without any source code. I refuse to perform this to "crack" a program to bypass service agreements or licensing, but if the programmer or company is now no longer in business and uncontactable, then I can get your system operating again.
