Ah good old HIEW. It's the simplest and nicest disassembler - open a file switch to disassembly with one keypress. Move one line or one byte at a time for defeating code that jumps in the middle of instructions, edit the assembly (ok code bytes) in place with live preview what instructions you're writing. All in 130KB of code :) http://www.hiew.ru/ EDIT: I wonder why is the author using a version from 2004 though...…
Also cygwin's midnight commander (when it fits the purpose).
I love console tools :)
