I recently discovered that the Blade Runner adventure game is now compatible with ScummVM, the best adventure game emulator in the world. So I dug up my old CDs and I have to admit, that game still is amazing!
I also prefer to play all my classic Sierra Quest games through ScummVM, and with the recent Humble Sierra Bundle, I went all legit. No more grey areas in my library
ScummVM started as an emulator to run Lucasarts adventure games based on the scumm engine (Script Creation Utility for Maniac Mansion). Classics like Monkey Island, Indiana Jones, Full Throttle, The Dig and Day of the Tentacle all play flawlessly.
You can choose to add graphical filters to the games to smooth out some jaggies, or play in the original low resolution. You can also emulate some older sound cards to give it the authentic 90’s sound, or use general midi sound fonts of your liking to make these old games sound like they have full orchestral sound tracks.
