砂の記憶 FBD 11, the first record
砂の記憶 — Nyolfen's track for In Falsus, registered by the English community wiki as Memories in Noise — spent its first weeks split across two wikis and zero guides: Miraheze lists Memories in Noise at MIN 2 / EVO 5 / ULTIMATE 9 / FORBIDDEN 11 (Arc 1, ver 1.0.2c), wikiwiki.jp lists 砂の記憶 at the same four tiers, and no frame-level guide anywhere had walked the chart. This page follows the song's first documented full run frame by frame — Skrubby's PERFECT DIVE — from the cold open to the DIVE RESULT card, twelve frames in all: the card's judgment table pins the chart at 1562 judged notes on camera, and the Japanese title gets the illustrated, searchable home it lacked. Every fact below is on film; where the record is silent, the page says so instead of guessing.

All twelve frames come from Skrubby's PERFECT DIVE run — a clean gameplay capture with no webcam, captions or overlays. Tiers are cross-checked against both community tables (checked September 16, 2026): Miraheze's Songs page registers the song as Memories in Noise (MIN 2 / EVO 5 / ULTIMATE 9 / FBD 11, Arc 1: The First Lie, ver 1.0.2c) while wikiwiki.jp registers the Japanese title 砂の記憶 at 2 / 5 / 9 / 11 — each table carries this one Nyolfen track. The result card's 1562-note judgment table matches the song-list count — verified on screen, note by note, for the first time. Each step deep-links to the matching moment in the source video.
Cold open: the chart starts on camera
- 1
Cold open: the chart starts on camera
There is no song select detour in this video — it opens with the field already live, the score climbing from zero as yellow notes cross the line. Two EXACT labels and a gold hold ring are already at work at 000'874'098 with the combo watermark at 14. For a page that exists to document a single run, that matters: nothing about it is hidden. The tier itself gets confirmed later, printed on the result card as a red 11 flag.

Twenty seconds in, accuracy at scale
The opening stream sets the terms: a white beam rides the center lanes while the combo watermark reads 174 at 011'103'891, every visible judgment an EXACT. FBD 11 charts do not warm up slowly — density and precision arrive together. The encounter bar along the top is already climbing toward its first star, fed by exactly this kind of clean chain.

The first minute: staircases and lasers
- 3
Twin staircases fold across the lanes
The first big objects arrive folded: paired violet holds step down the field like staircases, heads judged on the line while their tails keep ticking. A gold hexagonal ring waits low right for the cursor between steps. Holds in In Falsus reward arriving early and leaving on the tick — at 024'241'976, this run traces both folds without rushing either.

A pink laser gates the upper lanes
Past the minute mark the chart starts gating space: a pink laser occupies the upper lanes while a gold hex ring parks low left and flick notes land at the line — 034'727'129 on the HUD. The reading order matters: ring first, laser second, flicks whenever they cross. Nothing here is fast; the tier's difficulty is how many of these layers the next minute stacks.

Twin cyan holds pour in parallel
Midchart's signature is width: two cyan holds drop side by side through an EXACT row at 050'902'909, forcing both hands to hold while the cursor keeps its own appointments. The encounter counter along the top has climbed past 200'000 by this point. This is the section that separates an EX+ run from a comfortable clear — parallel holds punish any hand that cheats early.

Midchart: bursts, chains and the long sprint
- 6
Gold flicks erupt under the beam
The back half opens with bursts: gold flick notes pop at the line while a beam pours down the middle, the HUD reading 068'236'597. Flicks are the chart's cheapest way to break a perfect run — they always arrive underneath something else. This run treats them as rhythm, not surprises, and the encounter bar along the top keeps paying out on schedule.

The cleanest frame: a green laser chain
The chart's most photogenic section: a green laser sweeps the right while a chain of white EXACT labels rides the line at 080'580'725. Every element the chart has taught — streams, lasers, chains — appears at once without colliding. If you are studying the video rather than playing it, pause here: the full FBD 11 vocabulary in one clean sentence.

The sprint home at combo 1521
The last minute is pure endurance: thin streams and short holds push the combo watermark to 1521 with the score at 097'795'165 and the encounter counter at 493'303. Nothing new is introduced — the tier's final exam is holding form through fatigue. The run stays exactly on pattern; every score you see after this is one hundred million and change.

The last notes, the banners, the receipt
- 9
The last hold, three EXACT from one hundred million
At 099'766'032 the chart is down to its final purple hold and a triple EXACT at the line, the combo watermark at 1538. The score crosses one hundred million a second later — 100'001'517 is where it stops for good. A PERFECT run needs every one of these last notes as EXACT; this run does not blink.

PERFECT DIVE, edge to edge
The splash lands full-screen: PERFECT DIVE — the game's mark for a dive with nothing dropped, every note judged EXACT, zero NEAR, zero BREAK. On this chart the claim covers 1562 notes. The banner pays off the whole page's premise: a record is only worth keeping if the run behind it is complete, and this one is.

The field dims, the score freezes at 100'001'517
As the splash fades the field darkens and the song's own closing word — CENTERED — hangs across the middle while the HUD holds the final number: 100'001'517. It is the last thing the chart shows before the receipt. The page records it as it appears: a performance text over a dimmed field, with nothing more read into it.

The receipt: EX+ and the 1562-note breakdown
The DIVE RESULT card closes the run with the numbers this page exists for: EX+ beside 100'001'517, a PERFECT DIVE banner printed on the card, the red 11 flag, and the judgment table — EXACT 1517 + 45, NEAR 0, BREAK 0: 1562 judged notes, matching the MAX LINK field exactly. It even prices the improvement: HIGH SCORE 099'969'510, DIFFERENCE +000'032'007. The title reads 砂の記憶 — the Japanese display of the song the English wiki registers as Memories in Noise — with the artist Nyolfen in Latin letters.

FAQ
How hard is Suna no Kioku FBD 11?
It sits at the top of the song's four-tier ladder — both community tables agree: Miraheze registers Memories in Noise (the song's English title) at MIN 2 / EVO 5 / ULTIMATE 9 / FORBIDDEN 11, wikiwiki.jp registers 砂の記憶 at 2 / 5 / 9 / 11, and the result card in this run carries the red 11 flag on camera. What the video itself shows is sustained FBD-tier density — staircases, gated lasers, twin holds, flick bursts — across 1562 notes end to end.
How many notes does Suna no Kioku FBD 11 have?
1562 judged notes — read directly from this run's result card: EXACT 1517 + 45, NEAR 0, BREAK 0, matching the card's MAX LINK field and the 1562 already logged on the site's song list. Community tables log the figure but never the breakdown; this card is the first on-screen proof, judgment table and MAX LINK agreeing note for note.
Is it Suna no Kioku or Memories in Noise?
Both are official — they are the same song's Japanese and English titles. The game's display reads 砂の記憶 with the artist in Latin letters, Nyolfen; the English community wiki registers the same track as Memories in Noise, and each table carries only this one Nyolfen song. This page keeps the Hepburn rendering Suna no Kioku in its URL and prose so players searching the on-screen title find it — and it answers just as well to Memories in Noise.
How do you unlock Suna no Kioku's FBD chart?
The community wiki lists it as a Chapter 1 (Arc 1) story-progression unlock — Miraheze files the song, under its English title, in Arc 1: The First Lie at ver 1.0.2c. This site has not independently re-verified the gate in-game, so treat it as community-sourced rather than confirmed. The video itself contains only gameplay, no story scenes, so the page is spoiler-free; if the in-game gate differs, the page will be updated.
What did the run behind this guide score?
EX+ at 100'001'517, a PERFECT DIVE — all 1562 notes EXACT — worth +000'032'007 over the card's listed HIGH SCORE of 099'969'510. Both numbers reach so high because full EXACT accuracy carries the score: 1562 consecutive EXACTs are the entire distance between this card and the 099'969'510 that came before it.
