There are some codes in this classic, and being the loser that I am, I decoded them.
The binary text on the missingno fail says "fear missigno"
The binary text on the medal for closing out the error messages is simply "b"
The ASCII text on the medal for closing out error messages says "I gave a cry of astonishment. I saw and thought nothing of the other four Martian monsters; my attention was riveted upon the nearer incident. Simultaneously two other shells burst in the air near the body as the hood twisted round in time to receive, but not in time to dodge, the fourth shell." This is an excerpt from War of the Worlds by H.G. Wells.
7 years later and still offering surprises. Great job on this one!
