It's that event that occurs about twice a year in which we ask you, our loyal users, to go out and replay all your favorite games supported by ScummVM. In addition to all the games supported from 0.11.1, we have several new ones for you. The Bizarre Adventure of Woodruff and the Schnibble, Lost in Time, The Legend of Kyrandia: Book Two: Hand of Fate, The Legend of Kyrandia: Book Three: Malcolm's Revenge, and Drascula: The Vampire Strikes Back have support added since then. Furthermore, the DOS version of Waxworks and the Macintosh version of I Have No Mouth, and I Must Scream are now supported.
So, what are you waiting for? Go out and start testing! Grab a daily build of ScummVM and run through the games and note any bugs you see on the way (which you should post on the bug tracker). Once done, post that you've completed the game on the forum post so it can be posted on the wiki page. Be sure to list the version of the game, language, and platform.
Good luck, and remember: have fun!
