In order to work doukutsu-rs needs to be paired with supported data files. This repository does not contain any data files.
Supported game editions and data file acquisition guides
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
directory. Until that is done, both doukutsu-rs and the vanilla executable have to exist in the directory.
doukutsu-rs can be used as drop-in replacement for
CaveStory+.exe. No modifications to game files are needed.

data folder (contained in
romfs) from your console using tool such as nxdumptool.
- doukutsu-rs doesn't rely on the original ROM or executable, you just need the data files, go to
RomFS optionsmenu 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/DLCoption), 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.
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.
