I wanted to use my mi box to let the kids play put-put on the television. To accomplish that, I connected a wireless mouse to it. As scummvm was not natively in the play store, I sideloaded it. It works, but I have 2 cursors. In the scummvm main window, I have a mouse pointer and a cross, which are some space apart. Only when I click, they come together. Also to click a button, you have to click above it, and drag onto it.
I didn't find the right solution from the Internet.
