2. Jet Set Willy: Spectrum Computing

Author: Mark Jeffries

Publisher: Spectrum Computing

Year: 1985

Third-party bugfixed version: 2007

Language: English

Jet Set Willy: Spectrum Computing came from Mark Jeffries's Jet Set Willy Editor published in Issue 12 of the Spectrum Computing cassette-magazine (January/February 1985). The game and the editor were discovered by Philip Bee in September 2002 - it was he who christened the game Spectrum Computing.

The original release of the game was incompletable due to several bugs. Andrew Broad analysed them in detail on his website, providing POKEs to eliminate the problems. A bug-fixed version, prepared by applying these POKES, has been publicly available for download since February 2007 when it was first published on TZX Vault.

Number of rooms which need to be visited to complete the game: 57

("The Fridge" [23], "Where's The Food ?" [24] and "Middle O'the Tree !" [36] can be omitted at the expense of a less time-efficient performance.)
