So I already have emulators, and roms, and a controller I like. My usual play is to just HDMI my laptop into the TV and play.

So this raspberry would allow someone else to use the laptop while I'm playing video games. Would it really have much utility to me beyond that?

How easy is it to set up and use?

Are there certain emulators that they recommend?

What other emulator systems would work on it? When I "got out" of emu-gaming, there were some buggy, but sorta-functional N64 and PS1 emulators out there. Whats the landscape like today?
