Ao Oni 2016 Restored

An unofficial preservation and restoration of Ao Oni 2016, based on an archived RPG Maker MV web build.

The previously available web archive was missing a large number of game assets and map files. This repository restores the files recovered from a surviving www build and converts encrypted RPG Maker MV assets back into a form that can be loaded directly by a browser.

Important

This is a preservation/restoration project, not an official release.
It does not claim ownership of Ao Oni or any original game assets.

Restoration status

Recovered from the surviving RPG Maker MV build:

Type	Restored
Images	922
├─ PNG payloads	900
└─ JPEG payloads kept under .png filenames	22
Audio	545
Map files	117 (Map001.json–Map117.json)
Remaining unresolved asset references	14

The restored tree contains:

img/
audio/
data/
  Map001.json
  ...
  Map117.json

Images

All recovered .rpgmvp image assets were decrypted and restored to the filenames expected by the web build.

This includes previously missing assets such as:

img/pictures/tobiraakete1.png
img/pictures/tobiraakete2.png
img/pictures/tobiraakete2_h.png
img/pictures/tobiraakete2_mika.png
img/pictures/tobiraakete2_takesi.png
img/pictures/tobiraakete2_takurou.png
img/pictures/tobiraakete3.png
img/pictures/tobiraakete3_mika.png
img/pictures/migitobira.png
img/pictures/hidaritobira.png

Some files contain JPEG image data internally even though the game references them using .png filenames. These filenames are intentionally preserved because changing the extension would break compatibility with the original web build.

Audio

All 545 recovered .rpgmvo files were decrypted to .ogg.

The recovered audio files were validated as Ogg containers after decryption.

Maps

All map files from:

data/Map001.json

through:

data/Map117.json

were recovered and included.

Still missing

The recovered build itself still references 14 assets that are not present in the recovered files.

Directory	Missing asset
audio/bgm	sdky_attack2
audio/se	Blow5
audio/se	RPG2_86
audio/se	sdky_attack1
audio/se	sdky_sadako_shock1
audio/se	sdky_tamao1
audio/se	sdky_tamao2
audio/se	shaking-and-clattering-1
img/characters	!$hirosi_cm_ride
img/characters	!$sdky_kotatsu
img/pictures	end-blue_h
img/pictures	sdky_kayakonote_page1
img/pictures	sdky_kayakonote_page2
img/pictures	sdky_memo

See MISSING_REFERENCES.txt for the exact map/common-event locations that reference them.

Browser build note

Do not replace data/System.json with the encrypted-build version from the recovered package.

The assets in this repository have already been decrypted for direct browser loading. Using the original encrypted-build System.json would tell RPG Maker MV to expect encrypted assets again and can prevent these restored files from loading correctly.

Verification

A SHA-256 manifest can be used to verify restored payload files:

MANIFEST_SHA256.tsv

The restored image and audio payloads were also checked after decryption:

• 922 image files successfully decrypted
• 545 audio files successfully decrypted
• 0 unknown image signatures
• 0 invalid Ogg signatures
