1. Go to
http://file2hd.com/Default.aspx2. Go to any website, like Newgrounds
3. Find a game there, like this:
http://www.newgrounds.com/portal/view/5924734. Copy and paste the page url into the bar in File2HD, click Get Files
5. A bunch of links/files should appear below
6. Look for a .swf, with a name similar to the game name

7. Copy that and paste it into a notepad or somewhere where you can easily use it
8. Whenever you don't have connection and want to play a game, copy the link from the notepad and paste it into the url bar
It should look like this: (The game, but in a tab w/ full screen)

Hope this helped, and tell me if it doesn't work or if it worked
