I have been working on this for the past few days. It uses a (cloned?) Wemos D1 Arduino/ESP8266 board as a web server and payload uploader for direct jailbreaking of your PS4. I know most people won't need it because they just use their computers but this allows for full offline mode to prevent updates and can be taken with you to a friend's house, etc. and it is very cheap (the boards cost me 4-5USD each).
