My hand hovers over the desktop folder, heart quickening when the prompt asks for a password. I remember the first time I typed the wrong string and watched a secret vanish from reach. You can close that loop now — I will show you what to type, where, and when.
I’ve chased hidden files across Steam builds and small-studio releases; I’ll save you the trial and error. Read these short steps and you’ll have every password in Yunyun Syndrome Rhythm Psychosis without wasting a run.
A small folder sits in the top-right of the main screen — All Yunyun Syndrome Rhythm Psychosis passwords
First, the essentials. On the desktop in the first chapter there is a folder waiting at the top-right. Type rim de lacent (all lower case) to open it and claim the Y-unzip! achievement. The password rim de lacent is a skeleton key.
What are the passwords for Yunyun Syndrome Rhythm Psychosis?
Here are the four strings you’ll need and the conditions that reveal them:
- rim de lacent — Available immediately on the desktop folder. Lower case only. Grants Y-unzip!.
- Kurumi Kurusu — Appears after you complete the Q+ Channel and read Diary 1. Use it to open Diary 2.
- 0606 — Diary 7 becomes readable when your Denpa meter reaches 80% and after you’ve dragged Yunyun across the screen to trigger the scene.
- 0909 — The code for Diary.zip, which appears after Diary 7 or by hitting a specific Denpa percentage on a save.
Open Diary 2, Diary 7, and Diary.zip and you’ll get the Childhood Memz achievement. These three files are deliberate stopgaps — they don’t show up instantly, so patience and the right actions matter.
How do I enter the passwords?
Open the folder or the diary file and type the phrase or number exactly. For rim de lacent use lower case letters; Kurumi Kurusu follows standard capitalization but the game can be finicky — paste it to avoid typos. Steam achievements will register once the file accepts the code, and the UI gives immediate feedback.
If a diary stays locked after you type a correct string, check your progress: Diary 2 requires Q+ Channel completion and reading Diary 1. Diary 7 requires Denpa at 80% and the in-scene drag action for Yunyun to trigger the entry point.
When do Diary 7 and Diary.zip appear?
Diary 7 appears after you push Denpa to roughly 80% and complete the interactive beat where you physically move Yunyun on-screen. Diary.zip drops after Diary 7, or once a save reaches the game’s designated Denpa threshold; enter 0909 to access its contents. Diary.zip is a lighthouse in a fog.
I’ve tested these on Steam builds and cross-checked with Alliance Arts’ releases and community notes on Moyens I/O threads. If you want to chase every achievement, focus on the Q+ Channel run first, then collect Denpa until Diary 7 appears.
If you still miss a file, what did you miss: a typed character, a dragged movement, or a percentage point — which of those will you fix first?
