• JetSet Willy II - Jet Set Willy II: The Final Frontier (DOS remake; originally ZX Spectrum game)

Looks like there are several versions of this project, which was created by Dan Richardson.

This appears to be the initial release, with date stamps from Oct 4, 2001. It seems like the the same version was available from the author's website as v1.0.

A newer version of Dan Richardson's site indicates that he released a later version 2.0, dated 25 April 2002 according to the news section. This version has not been preserved, unfortunately, but the other version I linked to in the quote above was uploaded to DIV Arena on 5 March 2002, and marked as the "final demo", suggesting that it should be quite close to this version 2.0.

It also appears that Dan Richardson's efforts to recreate Jet Set Willy II did not stop there, because I've found a later Windows recreation of the same game in Blitz Basic, found here. It was originally available from Dan Richardson's web page (archived by the Wayback Machine).
