Linus Akesson released the small C64 demo, Nine, at Fjälldata 2025. He is working on a video to explain how it works, but if you can’t wait, you can download the C64 executable or MP3 files for yourself. He also warns users about reporting abuse in the forums and not to feed the trolls. The audience praises the demo, calling it glorious, magical, and even trying to run the PRG file with a syntax error. One user speculates about the coding technique called “MULTIPLEXIUS.”
