How did game developers pack entire games into so little memory twenty five years ago?


"Software titles for home game systems used 64K to 128K cartridges and yet provided game play for hours along with various graphics, sprites and sound. It seems that the game systems themselves must have provided a fair amount of functionality (utility functions, libraries, hardware acceleration and graphics instructions) but the sheer number of images, music and sounds, animations, algorithms for game play and so on is impressive to fit in such an extremely small amount of space, and this was 25 years ago!"

The story is too old to be commented.
