Another GTW entry and yet another Codemasters non-release to go into the vault. Mission Jupiter is not a late title like CJ’s 4th, but infact a very early Codemasters game which was being converted from the Spectrum original by Derek Brewster.
John Airey was assigned to the task and completed a conversion of this average sideways scrolling SEU, complete with music by Adam Gilmore. However, unlike the Spectrum version the game never quite made it even though it was completed. The reason why we are not entirely sure – the game lacks a bit of polish compared to the Spectrum version – but Codemasters did release their fare share of crap in the early days so it does seem odd why this didn’t make it. To get a glimpse of how it might have looked released, you can check out the spectrum inlay which would have been used.
Reading the crack intro though, it seems a friend of the programmer obtained a copy and leaked it out… so maybe it was because of the leak that Codemasters decided not to release it? Alternatively the original game was released back in 1987, where as the cracked version surfaced in 1989. Possibly the conversion was very late and too late for Codemasters to release – another option to ponder.
The main thing is that the game has sneaked out and is fully preserved, but it would be good to find out the story about this game. The game’s author only seems to have programmed one other game, which was a text adventure for Atlantis Software, so he might be quite hard to find.
Do you know any more about this release?
