BMS: beatmania IIDX 17 Sirius — RAR 2021

beatmania IIDX 17 Sirius is a landmark entry in Konami’s long-running rhythm-game series, and it has since inspired robust community activity around BMS (Be-Music Script) — a flexible, fan-driven format that recreates arcade rhythm-game experiences on PC. This article covers the arcade release, its music and design highlights, and the 2021 “RAR” (Re-Arrangement/Remaster) BMS scene that revisits Sirius content: what it is, why it matters, and how to experience it today.

Why 2021 Was a Watershed Year

The search spike for "bms beatmania iidx 17 sirius rar 2021" occurred for several reasons: bms beatmania iidx 17 sirius rar 2021

1. The COVID-19 Lockdown Arcade Drought: In 2020-2021, arcades worldwide were closed. Players who missed the Sirius era (2009-2010) couldn't travel to Japan. Simulators became the only way to play. BMS packs were a lifeline.
2. The "Perfect" Conversion: Earlier Sirius BMS packs (from 2012-2015) had issues—missing songs, broken BPM gimmicks, or incorrect note colors. The 2021 repack (often version 3.0 or Final Mix) was the definitive edition. It included:
   • All 60+ arcade songs (including hidden boss songs like “Sense 2007” and “Snake Stick”)
   • High-quality 320kbps or FLAC audio (up from the tinny 128kbps of earlier rips)
   • Properly formatted .bms files for LR2 and beatoraja.
3. The Death of Flash & Rise of beatoraja: By 2021, stepmania (for DDR) had evolved, but beatoraja—a modern, open-source BMS player with graphical effects, gauge types, and online ranking—had reached maturity. Players needed a single, clean .rar of Sirius to drag-and-drop into beatoraja’s folder structure.

Step 3: Folder Architecture

• Place the extracted BM2DX17_SIRIUS folder into beatoraja’s songs/ directory.
• Open beatoraja, navigate to "Song Select," and look for the "beatmania IIDX 17 Sirius" entry.

Part 4: The Legal & Ethical Minefield

Let’s address the elephant in the arcade. Is downloading "bms beatmania iidx 17 sirius rar 2021" piracy?

• The Official Stance: Konami actively protects its IIDX intellectual property. The official INFINITAS subscription service (on PC) offers Sirius songs as DLC. Distributing a full BMS pack of the official songlist is technically copyright infringement.
• The Fan Argument: BMS tournaments (BOF, G2R) operate on original music, not rips. However, "Simulation" packs are viewed by many as preservation. Because the PS2 version of Sirius is out of print and arcade cabinets are dwindling, the BMS rip is the only way for new generations to experience Sirius’s exact charting.
• The Hybrid Reality: Most serious players do both. They own the official CDs for the music (Konami releases OSTs legally) and use the BMS pack for practice. The 2021 rar is often described as a "study tool," not a replacement for the arcade experience.

Part 1: What is BMS? The DNA of the Community

Before we touch IIDX 17 Sirius, we must understand BMS (Be-Music Source). Created in 1998 by cave (Yaneura no Taku), BMS is a file format designed for music games. Think of it as the sheet music for a rhythm game engine. This search query refers to a specific niche

Unlike an MP3, a BMS file contains:

• An audio track (typically .ogg or .wav)
• A chart file that dictates when notes fall, their type (scratch, single, chord), and their speed (BPM changes, stops, etc.)
• Metadata (artist, genre, difficulty levels from ☆1 to ☆12+)

The BMS format gave birth to a massive doujin (independent) scene. Events like the BMS OF FIGHTERS (BOF) became the Olympics of underground rhythm game music. Winning BOF tracks often got licensed into official beatmania IIDX games—a direct pipeline from homebrew to arcade royalty. The COVID-19 Lockdown Arcade Drought: In 2020-2021, arcades

When people search for "bms beatmania iidx 17 sirius" , they are not looking for the official arcade hard drive. They are looking for the BMS conversion pack—a fan-made translation of the official Sirius songlist into the open BMS format, playable on simulators like Lunatic Rave 2 (LR2) or beatoraja.

The Great BMS Conversion Effort

Between 2015 and 2021, a dedicated group of fans (known only by pseudonyms like "Gradius" or "BMS team 2nd") worked on converting every beatmania IIDX arcade release into BMS format. This involved:

1. Ripping the audio from the arcade hard drives or PS2 ISOs.
2. Re-charting every difficulty (Normal, Hyper, Another, and sometimes Black Another) from scratch in the BMS notation.
3. Synchronizing BPM changes and stops frame-perfectly.
4. Compressing the final folder into a .rar archive for sharing via torrents or file lockers.

Step 2: Extraction

• Use WinRAR or 7-Zip to extract the Sirius .rar.
• Look for a folder named something like BM2DX17_SIRIUS or IIDX 17 Sirius BMS.
• Inside, you should see dozens of subfolders named by song ID (e.g., korskmnz for Bad Maniacs). Each contains an audio file and a .bme or .bms file.

1. Breakdown of the Terms

• BMS (Be-Music Source): A file format originally created to simulate the gameplay of Beatmania IIDX. BMS files contain charts, audio, and timing data, allowing players to create and share original songs or replicate arcade songs in simulators like Lunatic Rave 2 (LR2) or Beatoraja.
• Beatmania IIDX 17 Sirius: The 17th arcade installment in Konami’s flagship rhythm game series, released in 2009. It featured a space/constellation theme, introduced the “Trick” gauge for casual play, and included iconic songs like Bad Maniacs and Session 9 -Chronicles-.
• RAR: A compressed archive format (like .zip). In this context, it indicates a downloadable file containing game data.
• 2021: The year the file was likely uploaded, shared, or last updated—long after the arcade game’s original release (2009-2010).
