Best thing about WotEF was the loader on the C64.
As usual it was a typical, load, show screen, load some more, hide screen, load a touch more and then run.
Well just as the loading screen appeared a really loud sampled scream (like a karate scream) is played. Scares the bejezus out of you.
As for the remake, why not download MAME and play Karate Champ by Data East, which was the game WotEF copied blatantly.

It also had a rather funny in between level game.
Fist 2 was bugged to hell, but was great!
