@Felthry @monorail seems like someone's already done it and it works for them https://reddit.com/r/dwarffortress/comments/3u975i/steam_controller/
@monorail @Felthry yeah, basically. Valve's CS:GO config maps stuff like votes, opening the buy menu… to a grid on the left touchpad. They also support custom icons. It'd be a bunch of work to set up though
here's an example for the radial variant https://partner.steamgames.com/doc/features/steam_controller/radial_menus
@Felthry @monorail depends on the controller, sth like the Steam Controller that just straight up comes with trackball emulation would probably work
