To make keyboard input work, you need to enable "Direct Keyboard Access" in the Ryujinx Input Settings.

Be sure to check out submodules first:

git submodule update --init --recursive

To build the module you'll need devkitPro.

Install devkitARM using pacman:

sudo (dkp-)pacman -Sy
sudo (dkp-)pacman -S devkitARM

Use dkp-pacman on macOS and Debian-based distros and pacman otherwise.

Also install the lz4 package:

# On Debian-based distros
sudo apt install liblz4-dev

# On Arch-based distros
sudo pacman -S lz4

# On macOS with Homebrew
brew install lz4

Then you can build the module:

make

You'll find subsdk.nso and main.npdm in the project directory. Move subsdk.nso to subsdk1 (for example) and main.npdm into an exefs folder in a mod directory.

• devkitPro for a development environment
• skyline-dev/skyline for the basis of the module
• RicBent/codedx for building an NSO
• xerpi/libnx for an AArch32 userland library
• Magic1-Mods/And32InlineHook for AArch32 hooks
