I want to get into speedrunning, and I know which games I will do at the start, but I want to do two games at once with the same controlller. I'd be using an Xbox One controller connectecdto my PC via USB.

I've googled the topic but all I find are threads of arguments between people saying it is or isn't possible...but I know you guys will know lol.

How would I do it? I know it's possible because we see it all the time...

Which games? I know for example that it is possible for snes games by running two emulators (snes9x) at the same time, having the same input for both and unchecking the "Pause when I active" Option. Still we would need to Know which games you are referring to
