This is a port of Ren'Py, a visual novel game engine, to the Nintendo Switch for homebrew purposes.

Note: Project is no longer in development, please use Switchroot Android with the official port of Ren'Py.

User guide

For users wanting to take a sample of the functionality of Ren'Py, place "renpy-switch-the-question-vXXX.nro" in the "switch" folder of your SD card.

For game authors wanting to port to the Nintendo Switch, use the "renpy-switch-sdk-vXXX.7z" package. Read "README.html" for instructions on how to port your project.
