#### Data files
|
|
|
|
In order to work doukutsu-rs needs to be paired with supported data files. This repository does not contain any data
|
|
files.
|
|
|
|
doukutsu-rs works fine with freeware data files or [NXEngine(-evo)](https://github.com/nxengine/nxengine-evo) or from a
|
|
supported copy of [Cave Story+](https://www.nicalis.com/games/cavestory+).

#### Supported game editions and data file acquisition guides
|
|
|
|
**Freeware**
|
|
|
|
doukutsu-rs works out of the box when it's placed in the same directory as the original Doukutsu.exe executable. On the initial
|
|
startup, doukutsu-rs will automatically extract the additional resources that are embedded in the vanilla game into the `data`
|
|
directory. Until that is done, both doukutsu-rs and the vanilla executable have to exist in the directory.

**Cave Story+**
|
|
|
|
doukutsu-rs can be used as drop-in replacement for `CaveStory+.exe`. No modifications to game files are needed.
|
|
|
|
**Original version (first released in 2011 on Steam)** - expand for instructions

The `data` folder is in the same place across all platforms.
|
|
|
|
If you want to use doukutsu-rs as a substitute for Mac version of Cave Story+ (which at moment of writing doesn't work
|
|
on 10.15+ anymore), do the following:
|
|
|
|
1. Find the doukutsu-rs executable:
|
|
- In AppVeyor builds, it's in `doukutsu-rs.app/Contents/MacOS/doukutsu-rs`
|
|
- In your own builds, it's in `target/(release|debug)/doukutsu-rs`
|
|
2. Open Steam Library, select `Cave Story+`, press the `Manage` button (gear icon) and select `Properties...`
|
|
3. Select `Local Files` and press `Browse...`.
|
|
4. Open the `Cave Story+.app` bundle and navigate to `Contents/MacOS` directory.
|
|
5. Rename the `Cave Story+` executable to something else or delete it.
|
|
6. Copy the doukutsu-rs executable and rename it to `Cave Story+`.
|
|
7. Launch the game from Steam and enjoy!

> [!WARNING]
|
|
> **EPIC GAMES STORE VERSION WARNING**
|
|
>
|
|
> Nicalis for some reason ships a stray `opengl32.dll` DLL from Windows 7 with the Epic Games Store copies of Cave Story+.
|
|
>
|
|
> However as the game is 32-bit and the dll is 64-bit it has no effect on the original version, but as it's a core Windows DLL and doukutsu-rs ships 64-bit builds and uses OpenGL, it's makes the game crash on startup.
|
|
>
|
|
> The fix is to simply delete `opengl32.dll`, as it's not used anyway.

|
|
|
|
Extract the `data` folder (contained in `romfs`) from your console using tool such as [nxdumptool](https://github.com/DarkMatterCore/nxdumptool).
|
|
|
|
**Important notes:**
|
|
|
|
- doukutsu-rs doesn't rely on the original ROM or executable, you just need the data files, go to `RomFS options` menu to just extract the files to SD card so you don't need to do any extra steps.
|
|
- Ensure you're dumping the files **with update included** (`Use update/DLC` option), as 1.0 isn't supported.
|
|
|
|
**Nintendo Switch homebrew port specific info**
|
|
|
|
If you're running the homebrew port (drshorizon.nro) on your Switch, you can avoid the dumping step, doukutsu-rs will
|
|
automatically detect and mount the data files if you run it over Cave Story+ in Title Override mode (hold `R` while starting CS+ and launch d-rs from hbmenu).
|
|
|
|
You can put your own data files in `/switch/doukutsu-rs/data` directory on SD Card, which will be overlayed over RomFS if
|
|
you run it in setup described above.

#### Controls

Same controls as the default for freeware and Cave Story+ keyboard.

|

To change, use the control customization menu or edit `doukutsu-rs\data\settings.json` within your user directory.
