Or just make the desktop mode actually function properly, yes it has one outside of the wierd controller menu one, but good luck getting it to work right, it's like it was written by AI.Retroarch is made for Emulator boxes connected to a television and controlled by a controller.
It's terrible for playing emulators on a PC. Maybe if they focused an ounce of effort for fixing mouse support inside retroarch it would be worth using on PC. I can't understand why the UI is so terrible on PC.
