I use this program to play Minecraft with a ps3 controller and it works flawlessly for that purpose, but the program contains a bug that makes the mouse fly uncontrollably across the screen if the controller is accidentally unplugged.
This works flawlessly in Mint 19, very nice if you suffer from mouse arm syndrome, I use it for a number of games that only use mouse, I even use it for surfing sometimes. On a windows machine I use Joystick 2 Mouse which is very similar.
Was able to play Megaman vs Ghosts n Goblins using my gamepad thx to this, works pretty well
Very useful for games with poor controller support. Runs quietly in the background, otherwise you may need to run it with --notray to edit your setup - that needs to be fixed.
