Overlay

This was a software I created to display bitmap graphics over a window of a Windows game. I wrote this back in 2007 for a company that sold casual-games and third party Windows PC games from their website. Their motivation was to monetize the screen space by showing advertisements on the PC games the same way they were selling space on their website.

To see how the concepts; API interception, graphic overlay, instrumentation of binaries, translate to a system today, I am reconstructing the software again. I put the code here for browsing, it will not compile. The book, Windows Graphics Programming by Feng Yuan, has been an excellent guide in this project.
