The Atari 2600 was released in 1977. It had 128 BYTES of memory. This comment is larger than that. The hardware this ran on was released in 1984. That's an eternity of time back then in terms of technology. If you look for this game for the commodore 64, or basically almost any other system, graphics are of similar quality. This map of this version is entirely different. The only version I know that was (probably?) using this map was the NES version.
