This guide will use [Dniel97's segatools](https://gitea.tendokyu.moe/Dniel97/segatools/releases), which is a fork of segatools that gets regular updates and will be needed to get the game running.
### Getting Started
!!! tip ""
Before we even touch the game, there are some prerequisites we should install to minimise issues.
Grab the latest version of the AIO installer from the [releases tab](https://github.com/abbodi1406/vcredist/releases). Make sure to get the version that installs both x86 and x64 versions.
Run the downloaded `VisualCppRedist_AIO_x86_x64.exe` and press next. The installer will proceed to download and install the required files. This may take some time.

!!! tip ""
Next we should make sure we have all the required DirectX files.
Run the downloaded `directx_Jun2010_redist.exe` and accept the License Agreement. You will be asked to pick a location to extract the installer too, it's recommended you create a new folder somewhere as it will extract a lot of files.
Go to the folder you extracted the installer too, find the `DXSETUP.exe` and run it. Accept the License Agreement and start the installation. Once it's complete, press Finish.
You can delete the folder you extracted the installer too once the install is complete.
SEGA games are generally distributed as a base game folder and sequential update folders. For SUN PLUS, this will be a base `SDHD 2.15.00` and an `SDHD 2.16.00` update.
<imgsrc="/img/chunithmsunplus/1.png">
!!! tip ""
The base game folder should contain an `amfs`, `App` and `Option` folder.
<imgsrc="/img/chunithmsunplus/2.png">
!!! tip ""
The update folder should only contain an `App` folder.
SEGA data is also commonly distributed as single `.app` and `.opt` files. These files are useful for archival purposes, but are not required to run the game. Always download the unpacked data for home use.
segatools is currently unable to be run from the `E:\` drive. Please ensure your data is setup on another drive letter.
!!! tip ""
Choose a location for your game data, for example, `C:\CHUNITHMSUNPLUS\`.
Copy/move the `amfs`, `App` and `Option` folders from `CHUNITHM SUN PLUS (SDHD 2.15.00)` to this new folder.
Copy the `App` folder from `CHUNITHM SUN PLUS (SDHD 2.16.00)` to your new game folder. When asked, choose to replace the existing files with the newly copied files.
Obtain unpacked copies of `chusanApp.exe` and `amdaemon.exe`. If these weren't provided with your data, join the [Discord](https://discord.gg/cZRUmEPK78) for assistance.
`segatools` is a loader and hardware emulator for SEGA arcade games. It will allow us to launch the game, as well as configure inputs and network settings. More information can be found at the [segatools gitea page](https://gitea.tendokyu.moe/Dniel97/segatools).
Download the latest version of segatools from [the release tab](https://gitea.tendokyu.moe/Dniel97/segatools/releases) of the segatools page. This will be a file named `segatools.zip`.
As segatools supports many games, the `segatools.zip` file will contain several more zip files. For CHUNITHM SUN PLUS, we will need to open the `chusan.zip`.
The configuration information for segatools is all stored within `segatools.ini`.
Open up `segatools.ini` with a text editor of your choice. We'll be using [Notepad++](https://notepad-plus-plus.org/).
`segatools.ini` is seperated into several sections, indicated by the section name in `[square brackets]`.
Most options will have comments describing their function and how to configure them. We will go over the most important ones below.
!!! tip ""
The `[vfs]` section contains paths to important game files. You can use either relative or absoloute paths, however if your path name has spaces in it, you must wrap the path in "quotations marks".
`amfs=` should point to the `amfs` folder, which should be in the root of your game folder. This folder should contain an ICF1 file.
`option=` should point to the `Option` folder, which contains game data update folders, with A**XXX** names. This should also be in the root of your game folder, next to `amfs`.
`appdata=` is a new folder created for the games appdata. You can either create a folder somewhere to point this too, or simply enter `appdata=appdata` to have a folder created within your `App/bin` folder.
The `[dns]` section is for connecting to a server, however this will also need to be changed for offline play. In most cases this will be set to your local IPv4 Address.
Open your Command Prompt from the start menu, and type `ipconfig`.
Find the line that says `IPv4 Address. . . .` and copy the address. This will normally be in the format of **192.168.x.x**, though this may vary.
Replace `127.0.0.1` with the IP address you copied from Command Prompt.

The `[gpio]` section is where we can change between 60 FPS and 120 FPS.
For 60 FPS, leave the settings as they are.
For 120 FPS, change `dipsw2` and `dipsw3` from `1` to `0`.
<imgsrc="/img/chunithmsunplus/gpio.png">
!!! tip ""
Save and close `segatools.ini`.
Before we can test the game offline, we need to open `config_hook.json` in a text editor, and replace its content with the following:
Select the last option from the menu to return to the previous menu, and then select the last option of the main menu to save your settings and continue booting the game.
If you get stuck at a `Waiting for Distribution Server` message, shown below, close the game and relaunch. This is caused by dipswitch settings not setting themselves correctly the very first time the game is launched.
If everything has been set up correctly, you should now be at the games Attract Screen.
Now we know the game is working, we can move on to configuring controllers and network access.
### Further Configuration
!!! note "Controllers:"
As there are several different input methods, each with different setup procedures, these will be covered in the [Controllers](controllers.md) section.
!!! note "Networks:"
Local Network options will be covered in the [Networks](networks.md) section.
