Konami had begun aggressively enforcing copyright on IIDX music on YouTube and file-hosting sites, while simultaneously the BMS scene pushed for more original content to avoid legal conflict. The "SIRIUS rar" represented a last gasp of an older, more anarchic internet where full game conversions were shared via anonymous cloud links. Its existence highlighted a paradox: fans loved the game so much that they were willing to risk legal liability to keep it playable, while the official copyright holder left the title in an effective abandonware state.
