DALL-E 2 is an AI system that creates images in a variety of styles given a text description of the image. Here I've asked it to create a landscape from descriptions of the splash screen of the game Zkul for the QL. In the first result, the skull was too small: zkul1.jpg Here are nine more attempts ...

Will you establish what the copy check is checking for and then make sure that feature is part of a new file? The basic idea is to only copy over the damaged file sectors, leaving everything else a...
