!!! danger "Please make sure you downloaded your data from an appropriate source.<br>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.<br>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.
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 overwirte when asked.

### Patching the game
!!! info "Go through the [Web Patching](../../extras/patchweb.md) 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."
| 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:
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
[gpio]
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
```
#### `[gpio]`
!!! tip ""
- If you have a 120Hz monitor, set `dipsw2` and `dipsw3` to 0:
```ini
[gpio]
dipsw2=0
dipsw3=0
```
- If you have a 60Hz monitor, set `dipsw2` and `dipsw3` to 1:
```ini
[gpio]
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.
<imgsrc="/img/chunithm/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.
