The LFSR-generated music reminds me of the old Atari 2600 game "Pitfall". The game had to fit in a 4K cartridge, so a lookup table of the attributes of the 255 "rooms" wouldn't fit. Instead, an LFSR (that fits in 31 bytes) generates the bitstream that describes the entire map. (Background: http://www.samiam.org/blog/20130606.html http://www.samiam.org/blog/20130606.html)
- to3m 10y agoThe BBC Micro game `Exile' used a mostly-randomly-generated map, with some manually-created areas here and there: https://www.stairwaytohell.com/gamehelp/MAP-Exile-BC.png https://www.stairwaytohell.com/gamehelp/MAP-Exile-BC.png (very large PNG) The patterns are quite apparent when zoomed out, but on the actual BBC Micro the display area was 128x128 low-res pixels (a 256x128 area on the map image), making it more difficult to spot.
