It is necessary to disassemble a binary file of non-trivial structure. The full manual on the device file I have, remained only to choose a good Tulsa. OS preferably Win, but will suit any.
You need a Hex editor which can during editing to highlight certain patterns and offset. The difficulty is often found in structures such as 2 bytes, of which 10 bits — naming markers, 6 — mark option. Ie you need to highlight these bit combinations of the size from the nibble to a few bytes.
Tried a plugin to notepad++, Hex Editor Neo, just a handful. Of free with hiliting nothing found. Hex Editor Neo patterns only in multiples of bytes. In Ubuntu the installer for all hex looked nothing hiliting does not know how.
UPD: Unicode support in string representation is very useful
