I love when people dig up new dirt on my favorite things from 30-ish years ago, in this case a playable prototype of a never-developed “talkie” version of LucasArt’s The Secret of Monkey Island 2: LeChuck’s Revenge. The folks at the venerable MixNMojo site have a good writeup, including a detailed archeology on the differences and new sound resources discovered, along with information and images of LucasArt’s internal debugging tool called Windex (which ran on a second monitor in Hercules monochrome graphics mode!). Neat.
