Procedural generation was also used to generate levels in the Pitfall game for Atari 2600. A single level was represented with a byte (!) and bits were controlling the number of rolling logs, holes, etc. There were 255 levels there and LFSR was used to go from one level to another, so the actual level bytes wasn't even stored in the ROM.
