    Are you talking about New 3DS and New 2DS here? Are you saying New 2DS has extra processing power over the New 3DS?
    Because according to the specs on this page, they share the same CPU/GPU/RAM:

    You don't need too much knoledge of the console to design a capture device...you'd need more knoledge in programming FPGAs, device drivers and software to communicate with those drivers. 3DSs(and most of other Ninty consoles) use a very simple way of transmitting video to the screen: pixel clock(this dictates when the data pins should be read), vsync, hsync and 8 pins for each of RGB colours which carry the said signal in parallel(so 3DS has 24bpp/8bpc image path via parallel data transmission)(I don't have that much experience in radioelectronics, but I understand the working principle because it's described on the 3ds hacking wiki pretty well). To be honest, designing an HDMI or DVI-D solution would be harder because those use a packet system and don't just shove the raw digital RGB down the cable. Oh and also usage of HDMI requires patent fees to be paid which isn't a desirable thing for a low cost device. And furthermore HDMI capture cards are also freaking expensive(that depends on the persons money, but still blowing atleast $200 on a capture device is a bit too much) and probably won't even accept this low of a resolution input(which would mean the 3DS->HDMI converter board would also need to work as line doubler/tripler/quadrupler). (WAIT, where can you get a VCR with an HDMI input!?)

    As for HorizonMod, I'll give it a try once I dig up my good pci-e wifi card(that's somewhere cause I've been using wired ethernet connection for my PC for more that two years now) and it'd be interesting to see how much it has improved(though I doubt anyone came up with a method to replace JPEG as the main video codec, which would still be bad for image quality). I'll update the OP after I test it.

    I really like idea 2 since it would give a high quality TV out without needing any extra hardware in the 3DS itself (so only a minor case mod for the connector would be needed) allowing it to connect directly to a screen. That is assuming that whatever screen you are connecting it to supports the weird resolution. I guess that most likely it wouldn't look correct even if it worked. Might require an external dongle to convert the resolution to something a monitor or TV can recognize, but IMO that's still an improvement over needing a whole board in the 3DS requiring a bigger battery cover to fit the extra hardware and in turn making the 3DS incompatible with every case and many pouches on the market.

    Plus the fact that the capture cards can only be used with a PC, so you can't simply plug it into your TV if you want to play on a bigger screen, which may not matter to many people but I'm sure there are others like me who would like the option to easily play on a bigger screen.

    Also, a 3DS capture card can only be used with a 3DS. An Elgato or AverMedia capture card can be used with anything that has TV output (assuming you have one of the models that accept analog input), so you get a lot more use out of it for that $200.

    Yes, I'm talking about the New 3DS and New 2DS. Sure they have the same specs, but you are forgetting a VERY important difference, because they have the same specs but the N2DS doesn't have 3D, it gets to use a whole new core just for screen capturing, since the N3DS has a core dedicated to 3D which goes unused on the N2DS and HorizonMod has been written in a way that turns that extra idle core into dedicated streaming core instead, so it gets considerably better FPS (even above 60 if you don't limit it).

    Citra is a good option, but things with too heavy use of the touch screen can be a pain to play, especially if they are action games (eg: Monster Hunter which uses the bottom screen for camera control turns really clunky). For most games though it's a great option so I agree, especially since setting native resolution to x8 or so makes games look amazing even in 1080p which is a nice bonus (if you plan to upload on youtube or something).

    VCR thing was just an example of a device that can capture stuff, thanks for the follow up on that with the pic:rofl2:

    Not really. With the right camera and setup, it looks much better than even NTR or HorizonM. I used an Ipad 2/3/4 (couldn't remember which one exactly) and got the videos to look real nice.

    I had an idea about capturing games that I've never seen tried out and I'm wondering why.
    I got some decent results capturing DS footage directly with my webcam many years ago, having my webcam propped up in weird ways to get it angled directly at the screen, of course it was a bit tricky to play like this and I couldn't hold the console completely still.
    When fully in focus the camera would get some weird rainbow glare so I had it slightly out of focus which meant the image wasn't perfectly clean but it was still in focus enough that you could see individual pixels.

    This made me think, wouldn't it be relatively easy to reconstruct the original image by using some simple form of image recognition to crop out just the screen (as long as everything stayed in frame at all times), given that the camera was high resolution enough and of good enough quality to discern individual pixels without excessive noise, and resize it to the correct resolution, applying some filtering to filter out the noise? The colors and contrast would always be off by at least a little compared to a direct capture (depending on the quality of your camera), but it would still be a huge improvement over just recording the screen with a camera. It would eliminate the shaking and for all intents and purposes should just look like a slightly desaturated direct feed, and you may even be able to fix that by filtering it and calibrating the filter so the colors look as close to original as possible.

    It seems like it would be such a simple thing to make a generic program able to do this, especially with modern computers having enough power to do it in realtime with ease. The only tricky part would be calibrating the filter to look close to the original with your particular camera, as that part of it would vary by camera, but it's not strictly needed.

    Of course it would be much easier to actually play the games if you didn't have to hold it in a specific way and prop up the camera but people who can't afford or aren't willing to spend the money on a capture card (or there just isn't one available for their preferred system) still do this anyway and it seems like it would be a godsend to those people.
    I did not know HzMod got such a large update, haven't seen that mentioned on the front page or anything. Still, the lower image quality mentioned in the OP is a valid point. JPEG (or other heavy lossy image compression) does not look great, and with the added compression of whatever streaming service if you decide to stream the games or even the added compression of a YouTube video, it will look doubly bad. It may be good enough for a stream that will only be shown once but for a video that will be viewed numerous times over however many years and will either give new visitors a good or a bad impression of your channel it could matter a lot more.

    Couldn't the converter board just be externally powered, solving the HDMI power issue?

    Also, about the n2DS thing, can't you use the extra core on a n3DS when 3D is turned off?

    The N3DS has a DEDICATED core for 3D, which goes unused on the N2DS. Even if you turn the slider off you don't get it's capabilities as when not used it's still dedicated on standby looping until you turn the slider back on, while HzMod has code specifically written in a way that uses whatever isn't being used, meaning even with 3D off you still lose at least some percentage of processing power. And yes, it's stupid console design:P

    Kind of cool that n2ds has an extra unused CPU core. As far as HorizonMod goes, does that allow you to stream/record both top/bottom and direct audio or you gotta use the headphone port?

    Pretty sure HzMod is only top screen, but if playing a game where the bottom screen isn't important then it doesn't really matter. Don't remember if there's sound unfortunately, been too long since I last used it:unsure:

    There's going to always be a market for something like this. I know people think the 3ds is "past its prime" for a thing like this, but I have one response for you: speedrunners. I really hope he does this, it would be nothing short of amazing.

    Stephen (Woozle64 on Twitter) is going to make a new Nintendo 3DS capture device (Old 3DS, since the N3DS is too complex in his words to disassemble) and most 3DS stuff runs fine on the Old 3DS. There is also a kit coming for the Original DS (so not the DS Lite)
