Impressive programming from more than 30 years ago explained

Pac-Man was released May 21, 1980 and went on to become one of the most iconic arcade games in history. It is beyond amazing that programmer Shigeo Funaki was able to create such a fun and challenging game in such a small package. Consider that a full page of plain text requires about 2KB, and Pac-Man fit was just under 14KB.

Thanks to the brilliant coders of today, we can explore under the hood of the Pac-Man code to understand how Shigeo implemented the artificial intelligence that made the game play so addictive.
