GHex
GNOME Hex editor for files
GHex is a hex editor for the GNOME desktop.
GHex can load raw data from binary files and display them for editing in the traditional hex editor view. The display is split in two columns, with hexadecimal values in one column and the ASCII representation in the other. GHex is a useful tool for working with raw data.
The GHex program can view and edit files in two ways, hex or ascii. Good for editing saved game files.
