I have been running 16 star on EMU for the past 2 weeks but I really want to stream my gameplay from my wii. Is there any good recommendations for a decent capture card that supports windows 10? If not what else can I do or should I just stick with EMU.
It's a little pricey but the Elgato game capture HD captures the Wii and it does it pretty well. It supports Windows 10 as well.
Don't listen to them. Wii's default output is red-white-yellow, so unless you bought a component cable for your Wii, the best bang for your buck is going to be the gv-usb2. It's a quarter of the price of an Elgato game caputre HD. Works just fine on Windows 10. Wii doesn't natively output any higher than 480p so there's no reason to blow a bunch of money on an HD capture card if that's all you're using it for.
Any standard AV capture card will work - even standard easycap makes. As long as you install the drivers (usually included with cap card) you're good to go.
