The MDR file is a binary file - I don't know much about those obsolete 20th century text-editors like emacs, but unless it can handle raw binary, you're stuffed.
It can, if you tame it appropriately. (Be sure to disable any input or output encoding.) Emacs even has hexl-mode for in-place editing of binary files. As far as I know, hexl-mode cannot insert or remove bytes, but you are probably interested in in-place editing at first.
I write programs to explore the file format and I guess the other investigators do too. I work in "C", I don't know what the others do. It would be good idea to have a repository of these explorer programs in source-code format for others to pick up and get off the ground more quickly.
Perl can be useful too, but you have to be careful not to produce write-only code. :-) Marko
