Heres some homebrew for the GBA:

I made a way to select objects on screen like a mouse by using pixel color.
Here is a video I made to explain how it works.

A or B buttons = mouse click.
Direction buttons = move mouse.

I'm providing the C source code and my batch file.
Check out my youtube channel if you want to see more random fun stuff.
Thank you and have fun programming on the GBA!
