In the nicest possible way, if you are coming out with comments like:
and the fact that you don’t know that you’ll have no chance, because you need either android or ios to run the app, of which you can get neither on the Pi, I think even if you could run it on Linux, you’d lack the technical ability.
Just checked and you can assign those axis to mouse.
Anyway the bottom line here is try it. Do you have a Pi 2 or 3? Google has an official droid build for the 3. The CPU in the Pi and phones are also quite simular also.
iOS is requires less RAM and CPU than Droid, because it the OS is much more optimised.
1 GB of RAM WILL run IF on Live. All background apps must be closed but it’s feasible. The IPhone 5s has only 1 GB of RAM and I can still run the latest version of IF.
