Yesterday evening, JJP released a long-awaited update for The Wizard of Oz. The new version 1.21 (download here) replaces the former version 1.18, and is what’s known as a “Delta Update”. This means that instead of having to download an almost 4 gigabyte image of the game’s entire file system, the Delta file only includes content that’s new or changed. In this case, that’s about 114 megabytes of goodies – which although still significant, will be a heck of a lot quicker to download than the equivalent of an entire DVD!

Since the process of installing a Delta Update will be new for the vast majority of WOZ owners (it was for me!), I’ve created a quick 3-minute tutorial documenting everything from downloading the update, decompressing it in the proper way on a USB stick, and finally performing the update procedure on the machine.

You’ll find the video below, and after the break I’ve also attached the list of changes in v1.21!
