Create an action in the flash game so it plays full screen. In flash go to publish settings and select windows projector to make it publish an exe file that plays through flash projector. Create a .ico icon for the game. Create an autorun.inf file i think its called and burn those three along with any xml or extra things your partner has used to make the game.
Here is what you would put in the autorun file
Code:
[autorun]
open=myFlashFile.exe
icon=myIcon.ico
The only issue is that I think some newer versions of windows fuck with autorun nowdays.
You can make an opening (splash) scene with option to play from the projector with an optional link to the site to play online.
