Installing option data

!!! tip ""

SEGA games receive content updates through option folders rather than direct game file updates.

For O.N.G.E.K.I., official options are named `A???`, where `???` represents a sequence of numbers.  
Community-created options often use letters instead of numbers to differentiate them from official releases.

After downloading option files, extract them into your game's `Option` folder.

```
📂amfs
📂App
📂AppData
📂Option
┣━📂A001
┣━📂A002
┣━📂A012
┗━ etc.
```

!!! info "Option numbers don't always follow a sequential pattern
It's common to see the numbers jump, for example A001 then A012"

Installing unprotected executables

!!! tip ""

O.N.G.E.K.I. executables are protected and will not run on a regular computer.

- Obtain unprotected (also called "unpacked" or "decrypted" by the community) copies of of the following folders and files:

```
▶️amdaemon.exe
▶️mu3.exe
📂mu3_Data
┣━📂Plugins
┃  ┣━⚙️amdaemon_api.dll
┃  ┣━⚙️chiffre.dll
┃  ┣━⚙️libhttp.dll
┃  ┗━⚙️QR_Image.dll
┗━📂Managed
   ┣━⚙️AMDaemon.NET.dll
   ┣━⚙️Assembly-CSharp-firstpass.dll
   ┗━⚙️Assembly-CSharp.dll
📝mu3.ini
```

- Copy all of the above to your data's `App\package` folder
- Agree to overwrite when asked

!!! warning "Assembly-CSharp Notes"

`Assembly-CSharp.dll` **must** match your game version.  
All other files can be reused between game versions.

Installing ICFs

--8<-- "docs/snippets/sega/common/data_icfs.md"

mu3.ini

!!! tip ""

Ensure that the `App\package` folder contains `mu3.ini`.

If this configuration file is missing, create one using the contents below:

```ini
[AM]
IgnoreError=1
OptionDev=0
DummyAime=0
DummyCredit=1
DummyJVS=0

[Sound]
WasapiExclusive=0
```

!!! danger "Warning"

When using the folder structure proposed in this guide, setting `OptionDev=0` in `mu3.ini` is required for the game to properly load Option data.

Installing segatools

--8<-- "docs/snippets/sega/common/segatools_install.md" - Find mu3.zip and extract it to your data's App\package folder

You should now have these files added to your `App\package` directory:

```
📂DEVICE
▶️inject.exe
⚙️mu3hook.dll
📝segatools.ini
▶️launch.bat
```
