Source footage
One video backs every still below: TrappyTheDemon's In Falsus sightread of WonderRoom2.0 on FORBIDDEN 10 (3:11, uploaded September 9, 2026). Deep links in each step jump to the matching moment.
The upload has no spoken commentary — its only caption track is auto-generated [music] filler — so every fact here is read off the screen and checked against the song catalog. The capture carries the creator's live-stream badge on its left edge — avatar, "CrabbyTheDemon" viewer-count chip, PKTR tag and LIVE badge; recorder overlay, not game UI — patched out of three stills with delogo fills measured on the 1600-wide frames; the eight gameplay stills and the result-card still caught no badge because the overlay fades in and out. The video itself is untouched and linked in full. The side-lane key labels read Umschalt and Leer — the player's system locale, quoted as seen — and a Windows start-menu panel floats over the result card for the whole count-up, closing only on the upload's final readable frame, which is the still quoted in step 11.

Confirm the chart: FORBIDDEN 10
The detail screen states the terms in red: a 10 on DIFFICULTY FORBIDDEN — the tier above ULTIMATE and this song's ceiling — beside the pixel-art Wonder Room jacket crediting ILLUST Rei Kurashima,りたお,すとろべ. A REFLECT panel pairs AYAME with AYAME at DIFFICULTY RATING 34, showing 1,200 and 900 in rewards. The panel is quoted as shown; how the encounter scores itself is not read into it.

Wait out the opening wedge
The highway fades in with lanes labeled A S D F, the side pads reading Umschalt and Leer on this player's system, and the song chip confirming FBD 10 at SPEED 7.00. One purple wedge rides the home rows while the score is still 000'000'000 — the intro buys a clean look at the lane layout.

Meet the REFLECT partner
Before the first beat, the REFLECT intro slides AYAME in beside a five-slot memory-card rail with two cards equipped, the score corner still reading 000'000'000. A loading tip quoted earlier in the capture sets the rule this pairing plays by: in Reflection Encounters the HIT bars are replaced by a single Progress bar.

Hold the first wide beam
The chart opens its argument early: a wide cyan hold stretches across the left lanes, judged EXACT EXACT at score 004'239'454 while a yellow flick diamond waits on the right edge. In this FBD chart holds are not breathers between taps — they are the workload.

Read the gold hexagons
Gold hexagon field cells fire on the pads at combo 14, score 010'565'998, judged EXACT EXACT EXACT. Field objects here judge like ordinary pads, so play them as taps, not decoration — and expect them between hold endings, not on free beats.

Split the twin wide holds
The mid-chart's signature set: a cyan wide hold covers the left lanes while a magenta diagonal carries the right, four EXACT judgements landing at 022'557'586. Both hands stay occupied at once — the catalog's 758 holds are built from crossings like this one.

Survive the center mega-hold
One white-cyan hold swallows the middle lanes at 036'232'938 while a magenta beam works the right side, EXACT NEAR EXACT landing while the hold is still down. The holding hand cannot help here — the free hand owns every judgement around it.

Respect the LATE NEARs
A LATE NEAR flashes over gold hexagon pads at combo 45, score 046'488'259. Judgement windows this tight turn half-beat hesitations into NEAR counts — the card ends with 84 of them, most earned in hold-dense bars like this one.

Absorb the mid-chart BREAKs
The run bleeds steadiness as the layers stack: a red BREAK flashes beside a purple diagonal at 062'129'966 while a gold flick lands low. The card ends with 92 BREAKs — this chart punishes tired hands right to the final bar.

Take the full-width panel
The finale beds the whole highway under one light-blue panel at 081'985'168, a purple wide beam crossing it with EXACT landing. It reads as a wall but judges as a single press — trust the lane bed, not the width, and keep the ending holds down through the last measure.

Read the result card
The count-up runs under a Windows start-menu panel the player never dismisses until the upload's final readable frame — the still quoted here.

Frequently asked questions
WONDERROOM2.0 · FBD 10How hard is WonderRoom2.0 on FBD 10 in In Falsus?
It is this song's ceiling and a full tier above its ULT 9. The catalog splits its 1,481 notes into tap 282, hold 758, field 242 and flick 199 — over half the chart is holds, which punish drifting hands rather than slow ones. The capture ends in a rank-A first clear with 92 BREAKs, a fair expectation for a first visit.
What does the result card show for this run?
EXACT 1164 + 141, NEAR 84, BREAK 92 — 1,481 judgements, matching the catalog note split exactly. MAX LINK 170, MISS GAUGE 10, HIGH SCORE a dash, DIFFERENCE +090'953'224, an IOTA row marked First Clear, and an ENCOUNTER RESULT of 000'071'813 with four of five stars and a CENTERED chip. The run is a clear, never a full combo.
What SPEED should I use for the FBD 10 chart?
The capture plays at SPEED 7.00, quoted off the in-game song chip. At this density the hold bodies stack across lanes, so pick the highest speed at which you can still read two overlapping wide holds — then keep it fixed while you learn the crossings, because the chart gives few free beats to re-adjust.
How does FBD 10 compare with the song's ULT 9?
ULT 9 is the rung below, carrying 1,131 notes against the FBD chart's 1,481 — and its split (field 423, flick 301) leans on fields and flicks rather than holds. WonderRoom2.0 itself unlocks along the story route covered in the song unlocks guide. EVO 6 (533 notes) and MIN 3 (448 notes) sit well beneath both.
