DSK2ROM is a great tool to make ROM files from DSKs. But is it possible to come back to DSK?
In one words, is it possible to extract the DSK from the ROM?

It should be. In essence DSK2ROM just generates a DiskROM followed by a disk image. Strip the DiskROM part and what remains should be a disk image. Maybe some tweaks like padding are needed but it should be fairly trivial.

Thankyou, but the problem is: how to recognize the DiskROM part, mainly when ROM is compressed. I'll take a try.

Seems the first 16K is the DiskROM part. Near the end of that, there should be a string "DSK2ROM 0.80 by joyrex 2007" or something similar. After that the actual content.

If the content is compressed, Pletter is probably used, I think.
