Yep, already tried it with dolphin and pcsx2. Luigi's mansion played and looked pretty good Kingdom Hearts 2 was too pixelated to be enjoyable.This is great, I've been waiting for something like this since June.
And it captures the whole screen, so you should be able to stream emulators and even other consoles.
Heres another video showing performance with Bioshock Infinite.
Performance is farely good, I think the Overclocking could possibly be dropped down a bit to preserve a bit more battery life.
