That idea's cool and all, but I would rather just use Citra, Ijs, lol...

That's why I said 'In the future, if modern video game consoles ever are given a DMCA exemption or the DRM provisions of the DMCA are otherwise no longer relevant and it becomes fully, defensibly legal to homebrew them'. The problem is, right now, homebrew and CFW are still, technically, illegal due to circumventing DRM. I'm saying, in the future, once the legal changes you allude to have occurred, this will allow for controlled digital lending, rather than having to specifically loan out 3DS hardware.

Not entirely accurate. The problem is that emulators for modern consoles (Dolphin, Yuzu, Citra, etc) involve the use of console encryption keys, which violates the DRM provisions of the DMCA. It's a large, legally untested gray area, distinct from Sony v. Connectix and the reverse engineering defense.

For the first part "yes but actually no" case, depending on the country. In some it will be ok to modify the console as long as you don't use it further for stuff that's illegal. For example modifying to run homebrew will be ok, while modifying to run so called "pirated copies" will not be ok. Again it's not universal area so each one interested needs to check local country law for this one.

For the second part kinda another "yes but actually no" case. The fact those emulators need the keys is not yet the case to kick them. It's the same as emulators in the past required BIOS files BUT DID NOT provide them. As long as Dolphin, Yuzu, Citra and so on will NOT provide the keys in their package / source code, they are in the clear the same way as emulators that require BIOS but DO NOT provide it. (Exception if said emulator would have it's own BIOS written from the scratch, quite possibly HLE, then it's ok).

Unfortunately in Yuzu's case that's what happened, the keys were put in the source code - I've checked personally - with last change at about year 2020. The keys were by the time Nintendo struck down Yuzu outdated but that doesn't mean anything here, the legitimate keys were in the code, this part can't be defended, no matter what.

Still, not a bad thing to have around and mess with from time to time.

This requires DS mode emulation which will never happen, instead consider switching to a DS emulator.

I doubt that is the case. Yuzu did not provide ANY keys. Can you share which file and line number you have found them? I'm pretty sure you are looking at Yuzu forks and not the original archived source.

Possible but maybe we should check with moderators if it's okay, after all it would be kinda... you know...
THAT or I will send you a PM for now just to be on the safe side.

EDIT - Good news, confirmed by PabloMK7 these weren't keys in Yuzu's case.

Great concept, unfortunately my games (tested Pokemon X/Y and Mario Kart 7) seem to run much worse than on the console - gets really choppy and audio frequently doesn't play at all or starts a few mins later. I'm not on a "bad pc" either, so I'm not too sure. Using O3DSXL. I've attached my log.

So, if the server crashes or stops connecting for some reason, the entire game closes. I was wondering if it was possible to have citra automatically save state before it closes to avoid losing progress?

Also had this same problem a few times when trying it out but in my case it just keeps trying to reconnect, fails and emulation freezes so the only way out is to quit everything. Is this problem an issue that can be ironed out in the future or is this related to the user's internet connection? Sorry if this is poorly worded, I'm not too sure how the two connect to each other.

ChibiMofo · May 16, 2024

How cool! Now you can play 3DS games in 2D even though you actually own a 3D capable 3DS!
Can someone please point me to an emulator that PS4 games in SD?

hamohamo · May 16, 2024

Really cool for the syncing of savedata feature. Makes it kinda of a docked switch in a sense.

You still have to use it. This is just an extension for that.

choconado · May 17, 2024

This seems like an amazing idea that has potential. If you can finagle getting to use the inputs on the 3ds itself while playing on the computer or whatever device, you'll have made a solution for streamers that beats everything out there right now. Hard mods are expensive, and snickerstream has a *ton* of downsides. While currently sure, someone can just stream playing Citra and roms, there's a high percentage of streamers out there that prefer actual hardware when they can get it. So yeah, add console control functionality, and you have a dream app right here.

tanius · May 17, 2024

It would be nice to be able to stream only the top screen and still be able to use the bottom one and the 3ds as the controller.

As I wrote in my post on page four - Pokemon XY and most probably ORAS will work badly without HLE AAC Decoder. Unfortunately, these files are very hard to find these days.

torosashimii · May 17, 2024

Am I correct in thinking that this would allow me to use my 3DS game's save file on Citra while I'm at home and then continue playing on my 3DS while I'm out? Sort of similar to docking/undocking a switch?

If so, that's great. Not sure why people are asking the point of this tool (I find some of the comments to be quite rude in fact). This is incredibly useful for people wanting to stream games but still play on their 3DS in their own time.

I don't need it, I won't use it, but still: I love it!

You can use 3D screens with Citra.

TheStonedModder · May 17, 2024

If anyone wants to do something similar (at least for save files) between a modded switch and emulator I’ll pay ya lol

I want to seamlessly switch between portable and higher quality pokemon

xsdfr · May 18, 2024

just tried this out with some monster hunter 4
the game runs smoothly both in and out of combat which is fantastic but the load times are either very slow or abysmal
getting into the game (loading extdata) takes ages and getting into hunts is also really slow
still very cool and impressive

If I understand correctly, it's a big "Yes But..." in that you have to stay connected to the turned on 3ds to use the program with Citra. It's NOT saving the file to your PC, but still to the 3DS regardless. like think of it as "streaming" the save file to citra rather than porting it.

only issues i tried from a N3DSXL as the source system was loading anything that wasnt cached yet, (Omega ruby). though while my PC by today's standards would be Potato. (Ryzen 5 3600/GTX 1080Ti/32GB DDR-4 3200) my PC was connected to my network by ethernet.

if this wouldnt be a lil hard to install w/o a working top screen... would let me essentially continue to use my ALBW O3DS XL.

You can get the IP in the bottom screen with Rosalina. Open the Rosalina menu (L + dpad down + select) then go to Debugger options, then enable debugger. Finally take note of the IP address and then disable the debugger.

My sentiments exactly.

Mad props man, this tool is a technological marvel. I have some quick questions about how it can be used. Do the game specific settings you set on Citra load when you start streaming from the 3DS? And if so, is it possible to install mods or texture packs for a game on Citra and have it load those when streaming the game from the 3DS? I think it would be a very rare to not have the mod installed on both the 3DS and Citra, but the texture packs would be a game changer. (Especially for Majora's Mask 3D)

Performance has been pretty decent so far, but the audio issues are kinda bad right now. Are there any plans to create an option to cache files on Citra to make load times faster, or use the user's cache files from running the games previously through a dump? (If you already do this, then please ignore my ignorance) Thanks again for making this, and if you need any help testing then let me know. I have a pretty decent library of 3DS games to put through the wringer.
