5. Risks & Warnings

Malware: Random .rar files from 2021-era forum links often contained trojans or keyloggers disguised as “game data.” Safe communities (e.g., r/bms, stepmaniaonline) rarely host full arcade rips.
Outdated data: Some tracks or charts may be missing keysounds or have timing offsets, as BMS conversion isn’t perfect.
Legal exposure: Downloading full arcade rips can lead to DMCA notices from Konami, especially if using peer-to-peer (torrent) versions.

Possible Scenarios:

Community Projects: In 2021, there might have been community-driven projects or tributes related to the game, possibly involving rare or specially created content (song packs, skins, etc.).
Game Updates or Re-releases: Konami periodically updates their music games with new content. While "Sirius" was initially released in 2005, there have been numerous updates and re-releases of Beatmania IIDX games over the years.
Events: The game might have been featured in gaming events, tournaments, or music festivals in 2021, which could be considered "rare" or special events for enthusiasts. bms beatmania iidx 17 sirius rar 2021
