CHUNITHM SUN

!!! danger "Please make sure you downloaded your data from an appropriate source.
This guide is unable to troubleshoot any problems related to bad or poorly managed data."

!!! danger "If you're coming from a previous version of CHUNITHM"

You'll want to create a new folder for the game and start from scratch.
CHUNITHM **DOES NOT** like being extracted over old data!

---

Preparing data

!!! danger "There are currently issues with running game data in the E:\ or Y:\ drive.
Please extract the data into other drives."

!!! tip ""

After downloading and extracting your data, we need to make sure your files
aren't set to `Read-only`.

- Right click the folder containing your data, then click on `Properties`.
- In the `General` tab go down to `Attributes`, untick `Read-only` and click `Apply`.
- A popup will appear, select `Apply changes to this folder, subfolder and files`
and press `OK`.
- Finally, click `OK` again to exit out of properties.

You should end up with a file structure as follows.

<img width="500" src="/img/chunithm/sdhd/setup/0_chunithmdata.png">

Create another empty folder named `AppData` next to them. It should now look like below.

<img width="500" src="/img/chunithm/sdhd/setup/0_chunithmdata_withappdata.png"> 

The `App` folder should have a file structure as follows.

<img width="500" src="/img/chunithm/sdhd/setup/1_chunithmapp.png">

??? warning "If your data doesn't look like this"

If your data looks like the third image:

- Create an `App` folder and move all files and folders from the image inside of it.
- Create empty folders named `amfs`, `Option` and `AppData` next to the `App` folder.

If extra files are present next to your folders, such as executables, scripts, etc..
**remove them. This also means your data was tampered with and we strongly recommend
getting new data from somewhere else.**

Updating the base game

!!! tip ""

Extract your patch's files to your existing data in a way that matches its
file structure. Agree to overwrite files if necessary.

Installing option data

!!! tip ""

CHUNITHM content updates are distributed through option folders instead of patching
the base game. They are named `A???`, with each `?` being a number. Custom options
distributed by the community might use letters instead, to distinguish them from
official ones.

Extract any options you've downloaded into the `Option` folder. You should end up with
a file structure as follows. **Do not be worried if you have fewer or more option folders.**

Installing ICFs

!!! tip ""

Install Configuration Files (ICFs) tell the game what version it is.
**Without this your game cannot go online!**

If your `amfs` folder already has a file named `ICF1`, skip this step.

Otherwise, obtain copies of `ICF1` for your game version and place it in
the `amfs` folder. If it is named something else, rename it to exactly
`ICF1` **without any file extensions.**

!!! info "Showing file extensions"

By default, file extensions on Windows are hidden. Enable them by navigating to
the `View` tab in File Explorer and select `File name extensions`.

Installing unprotected executables

!!! tip ""

CHUNITHM executables are protected and will not run on a regular computer.

Obtained unprotected (also called "unpacked" or "decrypted" by the community)
copies of `chusanApp.exe` and `amdaemon.exe` for your game version. If these weren't
provided with your data, join the [Discord](https://discord.gg/cZRUmEPK78)
for assistance.

Copy `chusanApp.exe` and `amdaemon.exe` to the `bin` folder of your game data. Agree
to overwrite when asked.

Patching the game

!!! info "Go through the Web Patching guide to learn how to use a web patcher."

There are **many** patches for CHUNITHM.

We will only bring up the ones we think could be genuinely useful.

!!! danger "As a general rule of thumb, if you're not sure what a patch does or you're not absolutely certain you need it, leave it alone, regardless of recommendations below."

Patch	Recommendation	Description
Force shared audio mode	Either	Force the game to use shared mode audio output, letting you listen to other audio sources while the game is running at the cost of audio latency.
Force 2 channel audio output	Either	Try enabling this patch if you don't get audio output at all.
Disable song select timer	Either	Disables the song select timer.
No encryption	ON	Disable encrypting network requests. Required if you plan to run a local server.
No TLS	ON	Disable checking if the server is HTTPS or not. Required if you plan to run a local server.
Bypass 1080p monitor check	Either	Disable checking if the monitor is 1080p when enabling 120FPS. Enable if you cannot set your monitor to 1080p.
Bypass 120Hz monitor check	Either	Disable checking if the monitor is exactly 120Hz when enabling 120FPS. Enable if you cannot set your monitor to 120Hz.

Installing segatools

!!! tip ""

- Head over to [segatools releases](https://gitea.tendokyu.moe/Dniel97/segatools/releases)
and download `segatools.zip`. **Do not download the source code.**
- Extracting the archive should give you a few more zip files. Find **`chusan.zip`**
and extract it to the `App\bin` folder in your game data.

You should now have a few more files inside the folder, as highlighted:

<img width="500" src="/img/chunithm/sdhd/setup/3_segatools_installed.png">

---

Configuring segatools

!!! tip ""

Since there is no graphical configuration tool for segatools, you will have to edit the
configuration file by hand. It is found in `App\bin\segatools.ini`.

It is recommended that you follow along using a text editor with syntax highlighting such as [Notepad++](https://notepad-plus-plus.org/).

Each following sub-section will correspond to a section in `segatools.ini`. If any
section is not mentioned, you can skip them.

!!! warning

If a key already exists in the section, delete everything after `=` and replace it with your
setting. Do not add another key.

```ini
[system]
dipsw2=1
dipsw2=1 ; WRONG!
```

[vfs]

!!! tip ""

If you've been matching the file structure as described in the [Preparing data](#preparing-data)
section, you can fill in this section with the values below:

```ini
[vfs]
amfs=../../amfs
option=../../Option
appdata=../../AppData
```

[system] (formerly [gpio])

!!! warning

As of 2024-08-20, the [gpio] section in segatools has been renamed to [system].

!!! tip ""

- If you have a 120Hz monitor, set `dipsw2` and `dipsw3` to 0:

```ini
[system]
dipsw2=0
dipsw3=0
```

- If you have a 60Hz monitor, set `dipsw2` and `dipsw3` to 1:

```ini
[system]
dipsw2=1
dipsw3=1
```

[gfx]

!!! tip ""

- Set `windowed` to `0` to run in fullscreen mode and `1` to run in windowed mode.
- If you have multiple monitors and you're running in fullscreen mode (`windowed=0`),
set `monitor` to the index of the monitor you want to run the game on.

??? info "Getting the monitor index"

Navigate to Windows display settings. Each monitor should be assigned a number.
The monitor index is that number minus one. For example, monitor 2 means monitor index 1.

---

Connecting to a network

!!! danger "Please choose one of the two solutions, not both!"

??? tip "Remote (Online Network)"

Head to the `[dns]` section inside `segatools.ini`. Set `default` to the address
provided by your network. **Do not add `http://` or `https://` to the address!**

```ini
[dns]
default=network.example
```

Then, head to the `[keychip]` section and set `id` to the keychip ID provided by your network:

```ini
[keychip]
id=A69E-XXXXXXXXXXX
```

Finally, you need a card number. Create a file named `aime.txt` inside `App\bin\DEVICE` and type in
your 20-digit access code if you already have one, or make one up if you don't. If you're making one
up, the access code **MUST NOT** start with a 3.

<img src="/img/chunithm/sdhd/setup/4_access_code.png">

??? warning "Local (ARTEMiS/AquaDX)"

Both of these options require non-trivial setup. Refer to the official guides for [ARTEMiS](https://gitea.tendokyu.moe/Hay1tsme/artemis/src/branch/develop/docs/INSTALL_WINDOWS.md)
and [AquaDX](https://github.com/hykilpikonna/AquaDX?tab=readme-ov-file#usage-v1-developmental-preview)
to set up a local server.
