Yeah, I know Dragon's Lair has been officially ported to ZX Spectrum (see
here), but not in the 'full video' mode like the arcade one!
So this is how could be Dragon's Lair & Space Ace in full video mode
Ok, it's not playable, but it gives an idea about how a Spectrum 128K could natively display videos.
Anyway, even like that, I would be sooooo happy to play the game @ home back then...
