# Decryption and Playtest Generation

*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](https://github.com/rphsoftware/OneLoader/releases) 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.
