The Mysterious Origins of an Uncrackable Atari Game
« on: September 23, 2019, 07:29 PM »
Released in 1982, Entombed was far from a best-seller and today it’s largely forgotten. But recently, a computer scientist and a digital archaeologist decided to pull apart the game’s source code to investigate how it was made. An early maze-navigating game, Entombed intrigued the researchers for how early programmers solved the problem of drawing a solvable maze that is drawn procedurally.

But they got more than they bargained for: they found a mystery bit of code they couldn’t explain. The fundamental logic that determines how the maze is drawn is locked in a table of possible values written in the games code. However, it seems the logic behind the table has been lost forever.

Here's the pdf of the paper they wrote.  Looks like some fascinating, detailed info about the code, including a discussing of a bug in the pseudo random number generator, etc: https://arxiv.org/ft.../1811/1811.02035.pdf

I've downloaded it to read.
