Im new to programming and I wasn't sure how to add a joystick to the teensy lc from the perviously made software in the original game boy zero guide part 2. I used the guide to get the main pcb working but i wanted to add this PSP 3000 one found in the link: https://thepihut.com/products/adafruit-ps...

I know this probably isn't the best thread but Im new to Gameboy zeros and i was wondering how you can get the status bar at the top with WiFi and battery life?
