The error message
Failed to load audio/se/%E6%89%8B%E3%82%B3%E3%82%AD%EF%BC%98... indicates that the game is trying to load a Japanese‑named sound effect file.
For reference, the URL‑encoded string %E6%89%8B %E3%82%B3 %E3%82%AD %EF%BC%98... corresponds to the characters in the filename:
- 「手」 → %E6%89%8B
- 「コ」 → %E3%82%B3
- 「キ」 → %E3%82%AD
- 「８」 (fullwidth digit 8, not ASCII "8") → %EF%BC%98
In RPG Maker MZ,
event code 250 is the command for
Play SE (Sound Effect). The "parameters" field specifies which sound effect file to play, along with its volume, pitch, and pan settings. In this case, the game is instructed to play the file named 手コキ８（中速～高速）.ogg_.
I checked the CommonEvent.json and the entry for event code 250 is correct,
and it is the same as in the raw file:
JSON:
{"code":250,"indent":0,"parameters":[{"name":"手コキ８（中速～高速）","volume":100,"pitch":100,"pan":0}]}
Translator++ did not touch this part, so the translation process should not be the cause. RPGM MZ save files (.rmmzsave) also do not store audio file names in URL‑encoded form. Since the game runs on NW.js with its own Chromium build, the browser version of the player does not matter.
Please check whether the file 手コキ８（中速～高速）.ogg_ actually exists in the folder audio/se. If the file is missing or renamed, the game will throw this error. If you do find that 手コキ８（中速～高速）.ogg_ is present in the folder, then honestly I don’t know how else to fix it, because I cannot code. All of the explanations I’ve shared here come from asking ChatGPT and Gemini.
