I know a similar myth story by an old teacher of mine. Here's his explanation: link to this video tl;dr: In Dino Dini's soccer, a bug in the pseudo random generator caused the AI to behave in a not so fun game breaking way, because emulators cleared the bit of memory the pseudo random generator took to seed itself. Many people still think this game is just terrible, but instead it's just a bug because people play the game 'illegally' on an emulator. Though he admits it's still just a bug all the same.
