+# Initial D Arcade Stage Zero configuration settings
+
+This file describes configuration settings specific to Initial D Arcade Stage
+Zero.
+
+Keyboard binding settings use
+[Virtual-Key Codes](https://docs.microsoft.com/en-us/windows/win32/inputdev/virtual-key-codes).
+
+## `[io3]`
+
+Cabinet specific inputs.
+
+### `test`
+
+Default `0x31` (`1 Key`)
+
+Key-binding for cabinet test button.
+
+### `service`
+
+Default `0x32` (`2 Key`)
+
+Key-binding for cabinet service button.
+
+### `coin`
+
+Default `0x33` (`3 Key`)
+
+Key-binding for cabinet coin switch.
+
+### `mode`
+
+Choose whether you want to use a xinput (Xbox controllers, etc) or a dinput (PS
+controllers, most wheels) type controller.
+
+### `restrict`
+
+Default `97`
+
+This setting scales the steering wheel input so that the maximum positive and
+minimum negative steering inputs reported in the operator menu's input test
+screen do not exceed the value below. The maximum possible value is 128, and the
+value that matches the input range of a real cabinet is 97.
+
+NOTE: This is not the same thing as DirectInput steering wheel movement range!
+Segatools cannot control the maximum angle of your physical steering wheel
+controller, this setting is vendor-specific and can only be adjusted in the
+Control Panel.
+
+### `autoNeutral`
+
+Default `1`
+
+Automatically reset the simulated shifter to Neutral when XInput Start is
+pressed (e.g. when navigating menus between races).
+
+### `singleStickSteering`
+
+Default `0`
+
+By default if you use a xinput controller, segatools will use both sticks for
+steering. While this is recommended for precision, it may be confusing to some
+people. Set this to `1` to use a more traditional control scheme where only the
+left stick is used to steer.
+
+## `[dinput]`
+
+Configuration for dinput controllers.
+
+### `deviceName`
+
+Default ` `
+
+Name of the DirectInput wheel or controller to use (or any text that occurs in
+its name) Example: TMX, Wireless Controller, T300, etc
+
+If this is left blank then the first DirectInput device will be used. If you
+don't know the name of your input device, you can find it in the windows
+controller panel. The quickest way to access it is to press Win+R, then type in
+`joy.cpl` and look at the list it will display.
+
+### `shifterName`
+
+Default ` `
+
+Name of the positional shifter to use (or any subset thereof). Leave blank if
+you do not have a positional shifter; a positional shifter will be simulated
+using the configured Shift Down and Shift Up buttons in this case. If you don't
+know the name of your input device, you can find it in the windows controller
+panel. The quickest way to access it is to press Win+R, then type in `joy.cpl`
+and look at the list it will display.
+
+### Note on pedal mappings
+
+Pedal mappings. Valid axis names are:
+
+`X, Y, Z, RX, RY, RZ, U, V`
+
+(U and V are old names for Slider 1 and Slider 2). The default values below are
+valid for a Thrustmaster TMX.
+
+### `brakeAxis`
+
+Default `RZ`
+
+Which axis to use for the brake pedal.
+
+### `accelAxis`
+
+Default `Y`
+
+Which axis to use for the accelerator pedal.
+
+### Note on button mappings
+
+These are dinput button numbers. Note that buttons are numbered from 1, while
+some software numbers buttons from 0. The default windows controller panel
+should show the correct ones, if it hasn't been replaced by the controller
+driver.
+
+### `start`
+
+Default `2`
+
+Button mapping for the `Start` button.
+
+### `viewChg`
+
+Default `3`
+
+Button mapping for the `View Change` button.
+
+### `shiftDn`
+
+Default `5`
+
+Button mapping for shifting down with the emulated shifter. (If no `shifterName`
+was specified)
+
+### `shiftUp`
+
+Default `6`
+
+Button mapping for shifting up with the emulated shifter. (If no `shifterName`
+was specified)
+
+### `gear1`, `gear2`, `gear3`, `gear4`, `gear5`, `gear6`
+
+Default `1, 2, 3, 4, 5, 6`
+
+Button mappings for the physical shifter, if one was specified via the
+`shifterName` setting.
+
+### `reverseAccelAxis`
+
+Default `0`
+
+Inverts the accelerator axis if set to ‘1’. This is needed for certain
+controllers like the DS4 or Dualsense.
+
+### `reverseBrakeAxis`
+
+Default `0`
+
+Inverts the brake axis if set to ‘1’. This is needed for certain controllers
+like the DS4 or Dualsense.

+## Supported games
+
+- Initial D Arcade Stage Zero Version 1
+- Initial D Arcade Stage Zero Version 2
+
+## General remarks
+
+- The minimum version of Windows that this game supports is Windows 8
+- Most of the game is in japanese, even in EXP region mode.
+- This game is hard to set up. You may encounter weird errors that are hard to
+  diagnose
+
+## Known issues
+
+- The game will run in a semi windowed mode, even when set to fullscreen.
+- No DirectInput force feedback (future Segatools enhancement)
+- Felica.txt cards do not work with Version 2 of the game
+
+## Data and game setup
+
+1. Get the data
+1. Ensure the game files are not marked read-only
+1. Start up your favorite ALLNET server implementation in the background.
+   Without it you won't be able to save your progress whatsoever.
+1. The data releases have the following structure:
+
+- `package/`: Game data
+- `opt/`: Addon data
+- `amfs/`: Metadata
+
+4. Unpack segatools to the `package` directory
+5. Create an `appdata` folder (this isn't Windows APPDATA) in the data release
+   next to `package/`, `opt/` and `amfs/`
+6. In the `[vfs]` section of `package/segatools.ini` set the paths for the
+   folders:
+
+```text
+[vfs]
+amfs=../../amfs
+appdata=../../appdata
+option=../../opt
+```
+
+1. In the `[dns]` section, set `default=` to your computer's hostname or LAN IP.
+   Do not put `127.0.0.1` here, the game specifically checks for and rejects
+   loopback addresses. This setting controls the address of the network services
+   server
+1. If you want to change the language to english, you can set `region=` in the
+   `[ds]` section to `4`.
+1. This will change the region to `EXP` which comes with a rudimentary english
+   translation.
+
+- Note for Version 2 of the game: You'll have to manually create a card ID and
+  set it up. To do so, change your `package/segatools.ini` so that the `[aime]`
+  section looks like this:
+
+```
+aimePath=DEVICE\aime.txt
+felicaGen=0
+```
+
+- Then, go into the `package\DEVICE` folder, create a text file called aime.txt
+  and fill it with 20 digits, for example `01234567891234567890`. Make sure to
+  save the file.
+
+1. Right click `start.bat` in `package` and run it as Administrator. After the
+   first run you may be able to run the game as a normal user.
+1. Once you're at the title screen, press 2 or 3 a few times to add some
+   credits, then _hold_ the Enter key for a few seconds to scan a card and start
+   a credit.
+
+- In some cases it might be necessary to run the game from the `C:\` drive. Try
+  copying the game there if for some reason it won't boot on a different drive.
+
+## Segatools configuration
+
+Configurable settings are exposed in the `segatools.ini` file. For a detailed
+description, please refer to [this document](doc/config/common.md).
+
+## Initial D Arcade Stage Zero specific configuration
+
+For configuring IDZ specific features, e.g. IO, please refer to
+[this document](doc/config/initiald.md).
+
+## FAQ
+
+### Where is the Free Play setting?
+
+In the SEGA Nu system supervisor program, which is not included in this release.
+A command-line tool to change this setting will be provided in a future release
+of Segatools.
+
+Do note however that Free Play is not advised for this game, as it will prohibit
+you from purchasing additional cars.
+
+### How do I get extra music?
+
+Play through the story and also rack up your mileage.
+
+### How do I unlock extra gauges?
+
+Some will unlock in the story but most were time-limited online events. Try
+editing the "idz_unlocks" table in the MiniMe database to force-unlock them on
+your profile.
+
+### Why does my story progress keep resetting?
+
+If you are using minime, this is a known issue and will be fixed in a future
+release.
