Decryption and Playtest Generation

A guide on how to decrypt game assets

Omori's assets are decrypted by default, making them impossible to modify. The mod community has created tools to decrypt those assets and allow for modification.

The first step to decrypting the game is to make sure you have Oneloader installed on your copy of the game.

Open the game and go to the options menu. You should see a new tab labeled "Mods". An image showing the tab is seen below.

Here we are focusing on the "Decrypt" label. Here is an explanation of what everything here does:

Decryption Mode- Decides what the game will decrypt. "Everything" decrypts the base game with mods, "Base Game" only decrypts the vanilla assets, and "Only Mods" decrypts only the currently enabled mods.

Generate as Rpgmaker project?- Decides whether or not an Rpgmaker project file will be generated. Unless you're only doing basic asset editing, you will want to select "Yes" on this.

Start decryption- Clicking the button will start game decryption with the settings. It may take a while, so be patient! Progress is shown on a blue bar at the top of the screen. The decrypted assets will be in the OMORI game folder, under a new folder named "www_playtest_xxxxxx" or "www_decrypt_xxxxxx", depending on whether or not you chose to generate an RPG Maker project file.

Opening the Game in RPG Maker

Opening the game in RPG Maker MV is as simple as opening the project file found in the "www_playtest_xxxxxx" folder through the application. The project can be playtested normally, by clicking the green play button at the top.
