This release brings support for six new games: Myst, Myst: Masterpiece Edition, U.F.O.s (also known as Gnap), and Sierra's Hi-Res adventure games #0: Mission Asteroid, #1: Mystery House, and #2: The Wizard and the Princess.
There's also been a lot of bugfixes for Sierra's SCI games, the addition of Hercules rendering and font for the AGI games, an enhanced Sherlock games experience, and the addition of AmiUpdate on the Amiga port.
I see what you did there!
