French Plus only demo from 2016.
Unfortunately the initial loading screen "AMSTRAD.EU" causes the OSSC to lose sync but if you want to see it use the first link below.

From CPCPOWER:
"Small realization of Kukulcan working only with computers from the CPC+ range to participate in the composition "Croco or Dragon" organized by Amstrad.EU following an idea of Snake Plissken. In the end, why choose between Croco or Dragon, my heart swayed and suddenly, we have the right to 2 critters, with a preponderance for dragons. The first screen consists of the display of a title screen by section, allowing to see the amstrad.eu logo, then the image of the crocodile and finally the complete image, presses it on a key, allows to 'enable moving hard sprites to visualize my nickname.
For the 2nd screen, we have the right to an aggressive dragon in vertical overscan, which opens and closes its mouth according to the music (it's a disguised VU meter), and the 3rd and last screen, it's a frightened dragon in overscan . Note that the music used comes from a transfer made by Fabien Fessard."
