Chronology of the Development of Manic Miner and Jet Set Willy Games for the ZX Spectrum Created by Daniel Gromann (
[email protected]) Hosted on JSW Central Last update: 22 April 2021 This document provides a comprehensive list of all known release dates of games using Manic Miner and Jet Set Willy game engines for the ZX Spectrum (and some other selected games of MM/JSW interest). It embraces gamma-released games, unfinished projects (where demo or beta files have been released) and editors. It also lists other dates related to the development of MM and JSW games for the ZX Spectrum, such as the publication of maps and RZX recordings, the launch and demise of major MM/JSW-related websites and other milestones in the online activity devoted to the subject. Every effort has been made to ensure the accuracy of the information contained in this document. In some cases remarks like or a little earlier / or thereabouts have been added to denote the uncertainty if the exact date cannot be pinpointed. A one-day difference may occur between the date mentioned in this document and the release date as perceived by the author of the game if the information about the release was published on a website using an American time zone while the author was physically in Europe at the time of release (or vice versa). Any such discrepancies will be corrected upon request. If various events took place on the same day / in the same period, MM-related events are mentioned before JSW-related events. Game releases are mentioned before other events.
