An efficient hex editor

http://www.chiark.greenend.org.uk/~sgtatham/tweak/

Tweak is a hex editor. It allows you to edit a file at very low level, letting
you see the full and exact binary contents of the file. It can be useful for
modifying binary files such as executables, editing disk or CD images,
debugging programs that generate binary file formats incorrectly, and many
other things.
