Dolphin how to 16:9?

Hi there. Just want to know the settings for Dolphin Core (Win10) to render in true 16:9. Tryed several settings but it seems the Core Renders 4:3 Screen (ZWW, ZTP; Smash Bro etc). Cant take Screenshots bc Dolphin would Crash .

I don’t think we have the widescreen per-game hacks hooked up (yet).
