Someone posted a link to this site on the Flashcoders mailing list today. There's some very interesting Flash stuff and other miscellaneous programming related things on the site. However, you must check out The Flash-based version of "Donkey Kong." It's obvious a lot of time was spent to replicate the game engine, graphics and sound.
Look in the middle section for the "Games" icon--the first
icon to the right of that will launch the game.
