I have been playing flash videos using skyfire, but I would really like to play some games like chopper using flash.
How can I get flash enabled on Froyo? I have heard that Froyo supports adobe flash.
You can download the Flash Player 10.1 app from the Market or by going to http://adobe.com on your phone and clicking on the Get Adobe Flash Player button.
Not sure what you mean by "stock", I have a T-Mobile G2, it has Android 2.2 out of the box, and Flash was pre-loaded. There is flash handling enabled in the browser and (I presume) in the YouTube application.
