Pico Android Gamepad

https://www.raspberrypi.com/news/custom-usb-games-controllers-with-raspberry-pi-pico-hackspace-42/ This project makes a similar gamepad for PC using keyboard keys for the input presses, is there a better method for android or would this work

thonny and u2f files are important for this project do you know which gpio pins to use... also look into direct input and xinput.

i found GP2040 CE https://gp2040-ce.info it's xinput and has gpio diagrams for all the buttons, should serve my project's needs perfectly!
