Going back to the late 1980s one of my friends had this on his amstrad greenscreen. fun times.
If you timed it right you could jump over the dragon immediately after the snap happy gator room without dying. no need for the sleeping potion.

Now, fast forward a year or so and my family had moved away but i now had a c64 & finally got the dizzy collection on it. i must have tried 100 times, but you could never seen to jump over the dragon on this version without the sleeping potion.

Just a random bit of geeky trivia. no real use to it, but I'm just putting it out there.
Maybe an amstrad usercan verify? or am i just making it up?
Cheers
