GM HTML5 can export exes as well. Why would you want to hack Chrome to do it?
Google Chromium is open-source, right? So is there a way to hack it to bits and bundle our html5 games in with it to make it a standalone EXE?
Doing this would make your website about as popular as those websites created entirely in Flash.
Man... I could even make entire WEBSITES with this, it's like, breaking all the rules! I'm very excited, this is going to be a very respectable tool for web development I'm sure.
