About

The ZVision was the engine used by Activision in Zork Nemesis and Zork: Grand Inquisitor.

This engine was added by the GSoC student RichieSams to ScummVM as part of the GSoC 2013.

The ScummVM engine uses Marisa Chan's ZVision re-implementation, which is available from http://github.com/Marisa-Chan/Zengine, as a reference.

It should be noted that from a technical viewpoint, this engine has nothing in common with the MADE engine used for Return to Zork. It should also not be confused with the Z-machine which is the original Virtual Machine used for the original Zork text adventure games.

Status

Both Zork: Nemesis and Zork: Grand Inquisitor are completable
