On the topic of wrappers, has anybody looked into Chromeless?
Also, Zinc 4.0 works with HTML5 for desktop apps.
<img src="http://www.multidmedia.com/common/img/Features/HTML5.png" border="0">
inc 4.0 can now compile a Remote or Local HTML5 Project into a single file Desktop Application for Windows or Mac OSX. By leveraging the power of CSS, Ajax and core HTML5 APIs, Zinc 4.0 users can build compelling, interactive Desktop Applications from Existing & New Web Projects.
That's of course.. if you want to pay $700 ;)
Depends on how serious you are with your game...
I tried the trial and it just wraps it all in an exe that relies on Internet Explorer already installed on the system... It's a semi-decent solution...
Personally I'm not sure if any of this is the right solution for me anymore, as I need a way to be able to make my game go fullscreen and have the option to control from a menu between fullscreen and windowed mode... I also need to make the game look like it's not even a browser so...
