I really like the idea of building a DIY adaper like this, i was going to make one originally to use with consoles but changed my mind about getting a console.
Now PSNow is available for PC, it clearly states that you need a controller to play any game, keyboard and mouse are not compatible.
Is there any chance that this will work with PSNow? if so does it mean that i will have to connect my other PC to this one to get it working?
