The case with Cool World was the Paramount only green-lighted the film because they tought it could compete with Roger Rabbit, they re-wrote the whole screenplay without the director knowing, and when they brought in the new script the day the sets were finished, it's rumoured that Ralph punched the studio owner's son in the face when he handed over the altered screenplay. But I don't care that much, even if the film was done as he intended, it wouldn't be that good.
Still, the reason why Super Mario Bros. had to be toned down so much was because Disney bought the film, and brought in Princess and the Cobbler writers to add some jokes and lighten up the film. If you don't know already, I'm looking foward to work on a fan-edit of the movie, I did a audio-less fanedit on Youtube of the Car Chase scene, but it's pretty much an early choppy and messy version of the scene, I changed it quite a lot.
The best part is that deleting most of the dumb stuff will reduce the film's running time by 20 Minutes.
Anyway, I'm begining to raise some suspitions towards the artwork that is shown in The Legend of Zelda's Instruction Book, they look like screengrabs from an animated film, there is even little dirt and cel shadows around the characters:
