I kinda feel like people don’t really care, I mean the ones who care are here and they left these products behind, but we’re really a small fraction that barely counts, most just use these stuff, they just don’t overthink it.

I think you don’t need any special software, the linux kernel recognizes DS4 OOTB as a game controller, I tried it with Flycast (standalone, not libretro’s) and it was just plug and play
