Reddit mentions of PC to TV Converter

Not OP, but I am the guy who wrote the blog post/built the cabinet. A few things:

1. I suppose you can directly screw/glue MDF, but I didn't want to risk splitting it, and plywood takes screws on the edge much better. It's also much lighter, and since this gets moved around the office, making it (relatively) light was a priority. As for the subtle wood grain, I do in fact enjoy it! It's super classy!
   
   
2. We did solder all the wires to the microswitches. We'd had bad luck with crimped wire ends slipping off the microswitches before. The microswitches are also rated for some insane number of presses, so making them relatively permanent wasn't too big a deal. We've had to swap one or two out, totally not a problem (we just tossed extra switches and a soldering iron into the back of the cabinet so it's always there in a pinch!)
   
   
3. For the signal to the monitor, we bought a VGA-to-SVideo converter for that old school CRT feel. This is the one we went with, and then just ran the motherboard's VGA out directly into it.

Ouya is shit. Weak hardware, bad controller, Android OS (not optimal for emulation or gaming). Ignore it.

Wii is very good for the systems it runs. NES, SNES< PCE, Genesis, and such I know work well. Nothing 32 bit or higher. No Saturn or PS1. If you soft mod it, you can play Virtual Console N64 releases, but not anything else on the N65. Soft modding can let you play the entire Wii, Virtual Console, and GC library as well (make sure it's a Wii that can play GC games).

Connecting the Wii to a CRT TV allows for 240p output, which is phenominal and the best you can do. It's exactly what you want. In general, don't play SD games on HD displays. A CRT TV or CRT Monitor is what you want to use. Multiple resolutions, superior motion, superior blacks, and no input lag. Just what you want. More on displays:

Xbox360 and PS3 can also have RetroArch installed on them, and that can play many emulators. You need custom firmware however.

Alternatively, you can try a computer hooked up to a CRT TV with a converter box. I have heard issues with them, and have no idea if they are true or not. Typically they go to 480p, which is not optimal, but is very good. But on the bright side, they're very cheap so it might be worht checking out:

For controllers, go here:http://emulation-general.wikia.com/wiki/Recommended_Controllers

The PS3 controller works very well, but an external program needs to be installed in Windows. Do not use Motion in Joy, but instead use Xinput wrapper.

We use this:

Had it for more than a year now, works perfectly. We have a streaming NetFlix subscription ($7.99 a month), it provides more than enough entertainment for the time being.

Try an active adapter, they can be pretty cheap: http://www.amazon.com/gp/product/B00351VWKI/ref=oh_details_o03_s00_i00?ie=UTF8&psc=1

Basically, to tell you what we're trying to do, here's more information:

Mac running Qlab, "master mac" will be outputting 1 or 2 video feeds and an OSC control via Ethernet. The Master mac will be the only computer outputting sound through the headphone port. The master mac will be controlling 2 other macs via ethernet router and OSC control to 2 other Mac Minis, which will each be in charge of 1 or 2 video outputs each.

Each Mac will have thunderbolt to VGA port dongles which will output to VGA to RCA converters. Like this.

Then, we want to connect splitters, and then output signals to TVs on the ground.

You will need a converter box and a cable for each end. You will connect the laptop via VGA cable to the converter box. Then connect the box to the TV (either S-Video for TV1 or RCA cables for TV2)

(To get free shipping, you'd have to order something else.)

I haven't used that box, so I can't comment on it specifically. As for recommendations, since this works both ways, I'd just pick the bigger TV. If they're the same size, my guess would be S-video (TV1) would have the best quality.

Speaking of quality, it won't be great. TV has pretty low resolution compared to computer screens. But it should be passable.
