WISH Binary Viewer is an ultra-light, super-simple binary file viewer, inspired by George Peter Staplin's "Little Hex Editor Widget." It can open and display a file in any combination of hexadecimal codes, binary codes, decimal codes, and text content (ASCII or ISO Latin-1). There are simple copy, search, and save functions too; if you insist, and you're sure you know what you're doing, you can use WISH Binary Viewer as a simple hexadecimal editor for binary files. Requires Tcl and Tk.
