How do I rip from old games?

[Raccoon Sam]

A typical method is just popping the disc in and looking at the files inside. There's usually the .exe executable and then some folders or files that might hint to being graphics or audio or whatever.
What files does the disc contain? Are there folders inside with names like "GRAPHICS" or something?
Once you have you suspect files I recommend opening them in a hex editor and/or GGD.
