I have created a tool which makes hacking and unhacking a flash install incredibly easy.  It should work on most versions of flash, however I can offer no guarantees that it will work on versions that I have not tested on. (Note, after hacking flash the esc key is to be used to exit fullscreen mode for flash videos)

Special thanks to Andrew Brampton for his work with 10.1
