Dragon's Lair appears on the Sinclair ZX81!



Quote:
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!

I wouldn't have believed it unless I saw that with my own eyes. Amazing achievement

That's not a basic ZX81, it has mass storage available so it can stream movies in. Not that impressive.

From visual point it is very impressive, for gameplay this game sucks. I always want to try this game and by juding on scans in old magazines it was interesting game, but when I try it I change my mind.

In the video he clearly states that it will be fully playable so not just a 'Movie'

Um. What exactly did you think Dragon's Lair was anyway?

The point being that even this demo would be impossible on a real-honest-to-goodness 1980s ZX81, even with a Rampack. It needs extra hardware to stream the movies off - the only technical achievement here is decoding it to the screen... And that's not hard in z80 asm even with the ZX81's display encoding to deal with; many games came out back in the day with highres graphics.

Now if they could do Dragon's Lair in 16KB without porting the poor platform versions then I'd be impressed.

Didn't Dragon's Lair just stream movie snippets from laserdisc? I remember playing it once or twice in the arcades, purely because it looked cool. But the essence of the game was to click the joystick in the right direction at the right time, and I actually preferred to watch other people play it.

Having said that, to see the ZX81 output the video is impressive, but there is obviously something else going on to 'help' it out, so it seems this is more about using the ZX81 as a sort of dumb terminal, as opposed to the actual game platform. Mind you, a 1GB RAM pack for a ZX81 would be nothing short of BRILLIANT!!

I'd love to see how that was achieved - how many 16KB chunks of RAM could you get? You'd likely need a 16bit port decoder and page in as needed... complex wouldn't begin to describe it

@Dunny - HAHAHA! My point exactly. You'd need a separate computer just to take care of the RAM paging. Mind you, I've got a couple of ZX80s kicking about so I could use those....
:P
