Reddit mentions of Komodo Nintendo Gamecube AV Audio / Video/ SVideo Cable

There are a few things you can do. Firstly, finding an S-video cable will provide you with the cheapest and easiest visual upgrade. The linked version is the most common, but there are better versions available. It's said that a cable with just S-video and no yellow composite output will provide a better picture than a combo cable, but in my opinion, the step up from composite to S-video is far more noticeable than the solo S-video upgrade. Should you want one though, the best one on the market seems to be the one Monster released. The downside here is that S-video is becoming increasingly dated, and many new HDTVs don't have them. Make sure to check and see if yours has an S-video input first!

If you want to go even deeper down this rabbit hole, there is a community dedicated to getting the best visuals out of retro devices, notably the wonderful people at www.retrorgb.com. You'll find a lot of great info there, and in regards to the n64, it sounds like certain colored models were more apt for enhanced modding than the original charcoal version. Most of their recommendations center around displaying on old CRTs though, so if you really want to display on an HDTV, you'll need to really drop some cash.

Specifically, you'd need this beast of an upscaler. you'll see info about this thing on the RetroRGB site, but basically what it does is works solely to convert and upscale the SD output of the older consoles into pixel perfect HD images, with as little input lag as possible. It's not cheap, but many people swear by this device.

Last but not least, you could simply play the waiting game. There will inevitably be a successor to the Retron 5 that plays n64 games in upscaled HD the way the current iteration does. And while you wait, the GameCube, virtual console, and especially the 3ds version of OOT all have improved stability and performance overall.

Hope this is helpful!

I highly recommend this cable: http://www.amazon.com/gp/aw/d/B000NBWRBQ/ref=mp_s_a_1_1?qid=1453214381&sr=8-1&pi=SY200_QL40&keywords=GameCube+svideo&dpPl=1&dpID=41BfETVXkfL&ref=plSrch. It's cheap ($6), works for N64/SNES/Gamecube, and it has S-Video, which offers a better picture than the red/white/yellow composite. I use it with my N64 and have seen a noticeably better picture. It's also Prime eligible!

Some on this sub have had bad things to say about this cable for a variety of reasons, mainly that it doesn't offer "true" S-Video. I don't know anything about that and the technical aspects of video output, I just know that I feel I get a better picture with the S-Video than with just a composite cable.

However you come out on the S-Video issue, this cable is still a tremendous value even if you only use composite.

Since you say you're not tech savvy, I'm gonna assume you'd rather not hard-mod your N64 to output a component (480p) signal. Also, N64's output resolution is remarkably low so it doesn't take much to capture good looking N64 gameplay.

What you probably want is an S-video cable (this is the kind I use). I know it says for gamecube, but video cables for gamecube, n64 and snes are universally interchangeable, so you're good.

For capture, the best bang for your buck is gv-usb2. For streaming a composite or s-video signal it's pretty much the universal standard.

Hope this helped.

Third party replacement cables are cheap. This one is $5 http://www.amazon.com/Nintendo-AV-Cable-Bulk-Packaging-Super/dp/B000035Y6B/ref=cm_cr_pr_product_top

For a few dollars more, you can get one with S-Video out http://www.amazon.com/Nintendo-Gamecube-Audio-Video-SVideo-Cable/dp/B000NBWRBQ/ref=sr_1_3?s=videogames&ie=UTF8&qid=1404327120&sr=1-3&keywords=snes+svideo

I would get one of these. I use something like this with mine so I can plug in s-video to my elgato and the other into my gamecube with regular splitters on my audio ones.
