Key Mapping

only_keyboard.se goes like this:

Requirements

It depends on your system having PS Remote Play installed at /Applications/RemotePlay.app. If this is not the case, you'll need to modify run.sh accordingly.
The latest Command Line Tools needs to be installed.
Relies on Python 3 (kudos to willoftw). brew install python
You have to turn off System Integrity Protection via 'csrutil' in order for DYLD_INSERT_LIBRARIES to function on the newest macOS. (Thanks Ben for figuring this out!)

Setup

./build.sh only_keyboard.se
./run.sh

SE File Format

SE files are, generally speaking, a mapping between an input key to a DualShock input. See the only_keyboard.se file for a breakdown of the format.

How It Works

ShockEmu works by intercepting the IOHID calls of PS Remote Play application and presents an emulated DualShock controller. It also hooks into the input routines of the application to catch keyboard inputs, which then get mapped according to your SE file.

Pro Tips

Launch from Terminal

The alias below allows for typing play / enter anywhere in Terminal and have RemotePlay.app launched with the above keys mapped:

$ cat ~/.zshrc | grep play
alias play="pushd [REPOSITORY_ROOT]; ./run.sh &; popd"

Launch from Terminal + Key Mapping Image

Have Preview opening the key mapping image for you and RemotePlay.app launched:

Save this script somewhere (e.g.: [SCRIPT_DIR]/play.sh)

#!/bin/bash

SHOCK_EMU=$'[REPOSITORY_ROOT]'

open -a Preview $SHOCK_EMU/Images/KeyMapping.png

pushd $SHOCK_EMU
./run.sh &
popd

chmod a+x it and create an alias that looks like this:

$ cat ~/.zshrc | grep play
alias play=[SCRIPT_DIR]/play.sh

Enjoy! 🎮
