Speccy Version Actually Rather Good
Clearly the reviewer was more Zapp than Crash, or wasn't even there, because the Speccy version was very well received and accurate, IIRC.
Yes, as others have mentioned it was released by Elite. They released some decent arcade conversions - Bombjack, Commando, Space Harrier, Ghosts 'n' Goblins, and others.
I don't think the speccy version was multi-load (Bionic Commando was a year or two later), as mentioned by others. I remember lapping it/clocking Ghosts'n'Goblins on the speccy. Hard game, but I was obsessed with it in the '80s having played the arcade game in Spain on holiday (so 80s!).
I still think it's one of my favourite '80s games. Bought Ghouls'n'Ghosts on the SNES - that was hard too!. Love MAME :-)
Enjoyed reading this article... inaccuracies aside.
