Correction First: The Settings That Do Not Exist

This page used to open with a settings table containing five options that are not in Yunyun Syndrome’s menu. Here they are, because you will waste time looking for them otherwise:

Old claim	Reality
”Judgment Tolerance +/-20ms, the widest window the game allows”	No such setting. There is no tolerance dial. Windows are fixed and unpublished.
”Background Opacity 50% / Note Opacity 100%“	Not exposed as such. What exists is a Screen Shake ON/OFF toggle added in Demo Ver. 1.0.3 (Dec 5, 2025).
”Chart Speed Multiplier = Monitor Refresh Rate / 60”	Fabricated arithmetic. Note speed is a setting, adjustable during play since Ver. 1.1.0; it does not scale by your panel’s Hz.
”Automatic audio-sync ships disabled by default; flip it in Settings > Audio”	Half right, wrong label. The feature is automatic audio latency adjustment, added in the Nov 29, 2025 demo update. I cannot verify a default state.
”Online ranking mode applies stricter scoring rules”	Unverified. A Monthly Ranking feature exists (same Nov 2025 demo update). Nothing documents different scoring rules for it.

The real feature set is better than the invented one, because the real items solve the actual problem: this game’s charts are visually hostile on purpose, and latency compensation is per-song rather than global.

Preparation: Settings Before You Play

Here is the verified list, each item traced to the update that introduced it.

Setting	Introduced	Why it matters for Full Combos
Automatic audio latency adjustment	Demo update, Nov 29, 2025	Removes system audio delay from the equation before you chase timing ghosts
Per-song audio sync adjustment (local offset)	Ver. 1.1.0, Jun 30, 2026	One awkward chart no longer forces a global offset change that breaks your other songs
Note speed, adjustable during play	Ver. 1.1.0, Jun 30, 2026	Slow the scroll mid-chart for dense bursts, bring it back when you can track it
Judgment distribution display	Ver. 1.1.0, Jun 30, 2026	Shows whether your hits cluster early or late - the diagnostic that replaces guesswork
Skippable rhythm game start animation	Ver. 1.1.0, Jun 30, 2026	Saves seconds per repetition, which matters when you are grinding the same chart
Separate volume for story parts and rhythm parts	Ver. 1.1.0, Jun 30, 2026	Keep Qtie’s voice levels from drowning the music cues you are timing against
Screen Shake ON/OFF	Demo Ver. 1.0.3, Dec 5, 2025	Turn it off. The denpa staging is the charm; it is not the thing you are reading
Controller support	Demo update, Nov 29, 2025	Keyboard or pad both work; play wired if you are on a pad

Ver. 1.1.0 also expanded sort and search in the Songs menu and added more sections you can drive with the keyboard alone. Ver. 1.2.0 (Oct 1, 2026) revised the English text throughout the game, and Ver. 1.3.0 (Oct 9, 2026) added five playable songs - MEGA TSKR, Mecha Koi Ranman☆, RORO JUMP! (feat. CHiNCHiYA), Strawberry Cake, and Quit being a maid? Quit being a human? - free without DLC.

Judgment Windows: The Numbers Behind Each Hit

The honest version: WHO YOU has never published judgment window sizes. There is no millisecond table in any patch note I read, none on the store page, and the in-game HELP text covers difficulty ratings rather than hit windows.

What is documented is one window-related change: Demo Ver. 1.0.3 (Dec 5, 2025) “relaxed judgment windows for LONG NOTES endings”. So hold notes were the specific complaint, and the developers widened the release window rather than the tap window. That is a real signal about where the game’s timing friction actually sits.

Judgment	Exists in game	Published window
Perfect	Yes	[Unverified]
Great	Yes	[Unverified]
Good	Yes	[Unverified]
Miss	Yes	[Unverified]

The old table on this page assigned +/-20ms, +/-40ms and +/-60ms to those rows. I have no source for any of it, and neither does whoever repeated it. Genre comparisons (Muse Dash, osu!) describe those games, not this one.

What replaces the fake numbers is the tool 1.1.0 gave you: turn on the judgment distribution display, clear a chart you know reasonably well, and look at where the misses sit. A cluster on the early side means you are anticipating the beat; a cluster on the late side means your audio path is lagging or you are reading the note rather than hearing it. Both are fixable with local offset. Neither is fixable by typing a made-up number into a setting that does not exist.

Full Combo Strategy: From First Clear to Perfect Runs

A Full Combo means hitting every note without a single Miss. “Full Combo! YUN ROCK!” is the achievement row for it, and Steam’s public statistics put it at 77.6% ownership - which tells you something useful: three quarters of buyers manage one clean run somewhere, so the barrier is chart knowledge, not elite reflexes.

Phase 1: Learn the Chart (Runs 1-3)

Play a chart three times before attempting clean. Listen for the vocal hooks - these are denpa tracks, intentionally strange and catchy, and they are built around repeated melodic stingers you can hum. Humming the phrase is how you stop reading notes and start hearing them.

Use the first three runs to find: the densest note clusters, the syncopated sections between beats, and the visual effects that pull your eyes off the lane. Screen shake off helps with the third one.

Phase 2: Isolate Problem Sections (Runs 4-7)

The game has no section practice mode, so use what exists:

• Drop note speed during play (1.1.0) when you reach the section that blurs, then bring it back after.
• Apply a local offset to that specific song if your judgment distribution shows a bias only on this track.
• Re-run from the start and count measures to the problem area so you know where to brace.

Phase 3: Clean Run (Run 8+)

By now the easy sections are automatic and your attention is free for the two or three places that actually cost you the combo. If the distribution view shows your misses clustering on long note endings, remember that window was widened in December 2025 - if you are still dropping them, your offset is the problem, not your release timing.

The Intentional Miss Strategy

Some content requires you to Miss deliberately. “Clearly Paranoid Qtie” (9.1% ownership) is reached by letting Patootie take maximum conspiracy influence, which means failing charts on purpose - the opposite of everything above. When you need intentional Misses, pick the densest chart on the highest difficulty you can survive to start, because missing is easier when notes are dense and fast. Details in the endings guide.

There is also a legitimate middle path added in Ver. 1.0.7 (Apr 27, 2026): Awesome Keeb Modded Ver. from Part 2, described in the patch note as “a heavily modded awesome Keeb that instantly ends ‘Denpa Songs’ (Does not affect achievements or scores)”. If you want song completion without playing it, that is the sanctioned mechanism.

Chart-Specific Breakdowns

Note counts and exact BPMs are not published for any chart, so I am not printing invented numbers here. What is verifiable is the shape of the tracklist and the two chart names that appear in patch notes.

The prologue charts

Your first clears, and the ones almost everyone beats: YUNYUN DENPA OTW! at 96.0% and Time to explore! at 91.5% ownership. Full Combo territory is right here - Full Combo! YUN ROCK! at 77.6% confirms most players clear a chart without dropping a note.

The original songs

Four originals are named on the store tracklist: Denpa-tic Imaginary Girl “Q”, Peak Ecstasy!! Rim de Lacent☆, YUNYUN HARDCORE, plus two unlisted ??? slots. Peak Ecstasy!! Rim de Lacent☆ is Yunyun’s character song (voice: Haruko Momoi) and has its own music video. The row named Yun are an idiot. ships with the description “YUNYUN HARDCORE” at 23.8% - that is a song-specific clear, not a difficulty achievement.

Licensed denpa

The store page lists the licensed block, including INTERNET OVERDOSE, INTERNET YAMERO, Cirno’s Perfect Math Class, Princess Brave!, Princess Bride!, Shukusei!! Loli Kami Requiem, Miko Miko Nurse, PETTAN PETTAN TSURUPETTAN, summer is machine gun and winter is machine gun. Two of these appear in actual chart-fixing patch notes: Princess Brave! had its HARDCORE GAMER offset values adjusted in Demo Ver. 1.0.3, and winter is machine gun was added to the demo in Ver. 1.0.4 (Feb 25, 2026). When a developer names a specific chart and difficulty in a patch note, that chart is the one with the timing controversy - practice it with local offset available.

New in October 2026

Ver. 1.3.0 (Oct 9, 2026) added MEGA TSKR, Mecha Koi Ranman☆, RORO JUMP! (feat. CHiNCHiYA), Strawberry Cake, and Quit being a maid? Quit being a human? - all playable without DLC. Fresh charts are where your existing offsets will feel wrong first, which is exactly what per-song local offset exists for.

Timing Calibration: Killing Audio Desync

Desync is the single biggest reason a run you felt perfect comes back full of Greats.

The workflow that uses real features

1. Turn on automatic audio latency adjustment (present since the Nov 2025 demo update).
2. Turn on the judgment distribution display (1.1.0).
3. Clear one chart you know. Do not chase a Full Combo; you are collecting data.
4. Read the distribution. Clustered early means you are anticipating; clustered late means latency or reading instead of hearing.
5. Apply a small local offset to that song only (1.1.0), not a global change.
6. Re-clear and compare. If the distribution tightened, keep it. If it did not, you are not offsetting, you are practising - go back to Phase 2.

Hardware realities

The old version of this page published a table of millisecond offsets per input device, measured “across 12 calibration sessions”. I cannot substantiate those numbers, so they are gone. What survives as practical advice is narrower and true: Bluetooth audio adds variable delay that per-song offset cannot fully compensate, so play wired if you are serious about clean runs. The game supports both keyboard and controller since the Nov 2025 demo update, and 1.1.0 added separate story/rhythm volume channels, which is how you stop Qtie’s voice line from masking the downbeat you are timing against.

Important Notes

Ratings were a mess until 1.0.9. The June 1, 2026 patch note admits NORMAL, HARDCORE GAMER and TRYHARD were “internally identical” on the rating scale before they were unified, with DEGENERATE left separate. If you read a difficulty claim that assumes four cleanly graded tiers of payout, it was written before that fix.

Long note windows were widened deliberately. Demo Ver. 1.0.3 relaxed judgment windows for LONG NOTES endings. Holds are the documented weak point of the original tuning.

Offset is per song now. Ver. 1.1.0’s local offset means a chart that fights you gets its own correction. Do not global-nudge your way out of one bad chart.

English text kept changing. Ver. 1.0.6 (Apr 25, 2026) revised localization after public complaints, Ver. 1.0.7 fixed text with original-source references, Ver. 1.2.0 (Oct 1, 2026) revised English throughout. If a conspiracy or prompt reads differently from a screenshot in a guide, the text - not you - moved.

DENPA requirements moved down. Ver. 1.0.7 reduced the amount of DENPA LEVEL needed to reach 100%. Any total-DENPA figure quoted from before April 27, 2026 is describing an older target.

How Rhythm Performance Ties Into Progression

Every clean hit feeds the meters: DOKIDOKI on any chart, HYPE through conspiracy trend cards, YUNYUN through the golden yunyun cards, and DENPA LEVEL as the master gate for the true ending.

The bonus structure the game exposes is the one attached to the achievement rows: first-time clear, rank thresholds, Full Combo, and rate thresholds each contribute DENPA on every difficulty independently. [Unverified - the exact DENPA payout per bonus is not published in any patch note I read; measure your own DENPA delta per clear the same way you measure the meters.]

What the achievement ownership tells you instead: 77.6% of players have a Full Combo somewhere, but only 28.1% hold HALP! (the 100% denpa row) and 24.5% hold DONIDEMONARE (the true ending). Clean rhythm play is common; converting it into the DENPA grind is where the majority stops. That is the actual difficulty curve of this game, and no millisecond table was ever going to tell you that.

Farming specifics are in the stat farming guide and the DOKIDOKI 999% route.

Final Take

Three things matter most for consistent Full Combos, and all three are real features:

1. Kill latency first. Automatic audio latency adjustment on, play wired, judge your own spread with the judgment distribution view before touching any offset.
2. Per-song, not global. Local offset (1.1.0) fixes the chart that fights you without breaking the eleven that don’t. Drop note speed mid-chart on the bursts.
3. Stop chasing published window numbers. None exist. The documented tuning change is that long note endings got more forgiving in December 2025 - everything else is chart knowledge, which is why 77.6% of players have a Full Combo.

If you are chasing specific endings rather than clean runs, your rhythm performance decides which doors open, and the intentional-failure paths are as important as the perfect ones. The endings guide maps which charts and which failures lead where.
