Homebrew diagnostics for DS

[invdrcats]

Hello, I do repairs on non warranty DS models and its frustrating finding out if everything works. I have a flash cart but i want to make a simple program that shows all the buttons and highlights them when pressed, and also checks wifi and touch screens to speed up the process of the repair.
Please anything would help either a guide to show me how to make it or someone to help me program it

Thank you-
