Now I remember Dragon's Lair very well, from the Amstrad version with the jumping of platforms or trying to stay on the spinning disk without being blown off, or the interactive animated version which appeared as a laserdisc in which you needed to press a specific direction at the right time to survive. Both were simply brilliant games, but what has blown me away today is a ported Dragons Lair by ex-Ocean software coder Jim Bagley, demo'd on the ZX81!
This amazing demo was created for the ZX81 and shown exclusively at the Retro Computer Museum Valentine's Event 2015 at Snibston Discovery Centre in Leicester. It's incredible to see a game such as this on an 1 kB-16kb memory system so hopefully we see a release this year!
