What I'm thinking of is the same thing as a "file viewer," such as DOSSHELL
offers...something which will translate each set of 8 bits into a byte, and
display the character matching that byte. Needless to say, executable
programs
wind up making little sense...and I would expect the same from the bits that
make up a CD...but it might be able to see a pattern in the bits presented
as bytes...?
