Jet Set Willy is a sprawling 8-bit classic requiring the player to tidy up his own vast mansion, infested with monsters after a party gone wrong. Pixel for pixel, every screen now fits on a modern 4K display, and Retro Games Look posted a video showing all of them animated just as in the game. The result is startling and I only wish it were playable!
Someone should replicate this in real life with a bank of ZX Spectrums and CRT televisions.
