Shelter was originally released in 2016 by Porter Robinson and Madeon as an electronic song accompanied by a short anime film about a girl living alone in a simulated world. Its memorable melody made it a lasting favourite among fans of electronic music and anime, and independent creators later remade it in chiptune style, translating its synths into the bleeps and arpeggios of retro games. Those 8-bit versions spread through gaming videos, remixes and soundboards, where the familiar tune still works as a short nostalgic nod to both the song and classic game music.
