Actually, I never used an emulator at any point during this process.

I was playing my copy of FireRed on my GameCube (damn thing still gets some love) via my GameBoy Player.

I had that connected to my computer with a Dazzle DVD Recorder.

From there, I was using the broadcasting software that Justin.tv distributes in order to deliver my content directly to you. =D

i use the older version of this and its pretty great. You can use VLC, or the program it comes with to rip them on your computer.

EDIT: if you live in the north texas area, I'll rip them and put them on a hard drive you supply for free. Can't beat that!

If you're looking for something cheap, try an EasyCap. If you want something that's decent but not too expensive, check out a Dazzle DVC100. Or if you're big into quality and don't really care about the price, check out an AverMedia.

Then:

  Now:

• Image Software: Adobe Photoshop CS6
  

This one.

Here's what I use. Not nearly the best, but it's manageable for the average Joe or group.

Current

• Streaming: OBS Studio (Win 0.14.x)
  
• Overlay: HTML/Javascript w/ StreamControl writing data to JSON and JS polling it.
  
• Capture Device: Startech USB3HDCAP + XRGB-mini Framemeister
  
• WebCams: 2x Logitech C920
  
• Audio Mixer: Mackie Mix 8
  
• Headsets: 2x Audio-Technica BPHS1
  
• Misc: Powered Composite Splitter, Behringer HA400 Headphone Amp
  
• Stream Tools: Nightbot, TwitchAlerts
  
  

  Deprecated
  

• Capture Device: Dazzle DVC 100
  
  BPHS1s are kind of the standard for accessible and reasonably priced xlr headsets.
  
  I was getting decent quality out of my old dazzle before I switched, people just need to learn how to setup their bitrate properly to reduce artifacts and how to deinterlace their capture via amarectv or using the built in obs plugins (I used yadifx4 for the longest time) which do a nice, respectable job. Would I recommend a dazzle? Eh, it produces decent video for the price (got mine on ebay for $20), but has some compatibility issues - if you do a quick search for audio issues with the dazzle you'll find a couple threads. There are workarounds, but it's finicky.
  
  Ideally though, streams should be capturing component video. It removes the need for software/external hardware deinterlacing. The issue here is that you either need a TV that supports component, or a component->composite converter, which I've seen people have performance issues with in the past.
  My current setup uses a Framemeister to upscale the composite signal and handle the deinterlacing, outputting HDMI to the USB3HDCAP. The advantage is that I get to feed straight composite signals to any plain old CRT, which is great because I've been recording out of a suitcase the last few months while I move around.
  
  I build my overlays in JavaScript and HTML; there's a layer of logic that polls a local JSON file written by StreamControl for changes and updates them on the page.
  
  Just taking off on a flight. More info later. (It's later)
