Some protected DSK images won't load, probably needs more work since MAME has to convert the image to flux style data.

You could use the HxC utilities which includes an image converter, and convert the DSK image to MFM. This will also give the bonus of the new image being able to be written to.

As for Imperial Mahjong, the screen being offset to the right happens in certain games that use hardware scrolling (like Ghosts 'n Goblins, or Out of this World). I've mentioned it to Judge before, but it is a rather annoying bug.

IPF files should load, although AFAIK the loader was done entirely with Amiga IPF files so Amstrad ones might need some images sent to OG.

...Isn't writing back to the image file actually a bad thing, though? As in, it destroys its original state?

HxC is interesting, but doesn't seem amazingly fleixble when it comes to extracting data.

For example, if I have a copy protected disk, and I *know* the sector sizes on the disk are a lie, the software only allows me to load and view the image using the incorrect sizes, I can't tell it to override logic and show me / extract the full sectors ignoring the sizes.

The hxc track viewer is really handy for figuring out the copy protection. I used it while recreating the Tandy 2000 lotus 123 invalid sectors.

It's possible there isn't sufficient data to emulate the copy protection. Does it work on any other emulator?
