Hacking NTRCFW 3.4 Preview1(Support video output on New 3DS)

[Majickhat55]

It seems that preview 2 doesn't work on my system at all...
Here is the procedure I used for testing both previews:

Preview 1

Spoiler

N3DS
Deleted/uninstalled all preinstalled ntr.bin and bootntr.cia files
Copied across preview 1 ntr.bin to mSD root
Installed preview 1 bootntr.cia via DevMenu

PC
Launched preview 1 FakeProxy

N3DS
Launched BootNTR, started debbugger

PC
Opened preview 1 ntrclient
>connect('192.168.0.101', 8000)
Connection successful on first attempt
Opened ntrviewer
>remoteplay()
Video mirroring successful

Preview 2

Spoiler

N3DS
Deleted/uninstalled all preinstalled ntr.bin and bootntr.cia files
Copied across preview 2 ntr.bin to mSD root
Installed preview 2 bootntr.cia via DevMenu

PC
Launched preview 2 FakeProxy

N3DS
Launched BootNTR, started debbugger

PC
Opened preview 2 ntrclient
>connect('192.168.0.101', 8000)
Connection unsuccessful on first attempt, returns several lines of Python errors
Connection works eventually without changing the initial command
Opened ntrviewer
>remoteplay()
Video mirroring unsuccessful, returns invalid quality error
>remoteplay(priorityMode = 0, priorityFactor = 0, quality = 90, qosValue = 30)
Video mirroring unsuccessful, returns several lines of Python errors
Repeating the same command returns the same errors, even after 10 repeats
Connection to 3DS automatically fails over time

Does it work for you without using the proxy servers at all? Not that I think it matters but just curious. Also what seemed to fix it for me was merging the old/new preview folders and replacing whatever it asked. Both NTR.cia are exactly the same so that shouldn't matter. I notice I still get the revsc10000 error when I use my LAN on the computer vs Wi-FI on the same network. This version doesn't seem to like my LAN at all. Try running the commands as admin if you haven't and also consider adding the "take ownership" command if you haven't in your registry. I forgot to mention I did that as well on all the NTR folders. I ran the "take ownership" in CMD to overwrite the REG protection and give the system FULL access. Still can't get my LAN to work with Preview 2 though.

I'm curious how does the video streaming impact playing online?

Is it reliant on the potential speed of the router or does it really use my bandwidth?

Has anyone tried using ntr to stream on twitch? And how was the performance and quality on the viewer side? Any bottlenecking that results in poor twitch stream quality?

It doesn't seem to effect the throughput very much on a decongested network. Obviously it's still using your bandwidth but not enough to really effect latency. Unless you're playing something with high rendered animations, or high RAM usage of the DS. Seems the viewer takes direct advantage of the quad cores to boost streaming over wi-fi. Games that also access the extra memory in the n3ds seem to falter during gameplay. Especially Xenoblade 3D.

I did one the other day. I was WonderTrading Pokemon on stream and it seemed to work just fine. No quality loss for the most part and maybe an average of 7-10 dropped framed on the WT connections before it returned stable. You can find the video on my twitch archives. Twitch.tv/Majickhat

Is there a NTR viewer/debugger for mac available yet? How is the performance on OSX using virtual box and alike?

How about wifi viewers battles?

There's no OS X port of the viewer at the moment. I've been using VMWare Fusion with preview 1 and the performance is about the same as running off an actual Windows machine.

 

[Majickhat55]

I saw another vid of someone else testing the wi-fi battles and that seemed just as stable assuming you have a good stable connection. Frames were averaging about 25-30 on Preview 1. I can only imagine it has improved a bit on preview 2.

Thanks for the quick info dude.

And for the sound, all you need is male to male aux cable right? And does the sounds sync?

 

[Majickhat55]

Yeah, if you have a mic input on your PC you just need a M/M aux cable. I haven't tried sound myself since I have a dual headphone/mic jack on my Laptop and it only wants to read headphones. Still trying to figure that one out Lol.

It should be in sync for most screen recorders. I've noticed that using QuickTime on a virtual machine results in sound being a few milliseconds ahead of the video, but most people won't be using that setup.

Is it one of those combi audio ports? I think those are supposed to work with headphones that have built-in microphones so the headphone and microphone are working at the same time through the same port. Maybe the screen recorder you use will have settings to point the audio input to that port?

So how would I set up the sound with the ntr viewer?

NTR Viewer itself doesn't have audio mirroring features, you'll have to set it up separately with your screen capture software. Usually people connect the 3DS to their PC's line-in port via a double-ended 3.5mm audio cable and then set the audio input on their screen recorder to use that.

Yeah TBH I haven't tried messing with the sound yet. I do have two headsets with mic, but neither seem to register with windows when plugged in as a mic, only headphones. I use Bandicam to record the video so perhaps that can, like you said choose the correct mic device. Guess I'll test that now. I've also heard deleting the stock mic driver for the laptop will correct the issue.

Replaced the old NTRbugger/NTRViewer folders with the new ones by merging, not replacing entirely (for some reason a newly created config_xml throws the syntax error, I kept the old one from preview 1 in the NTRbugger folder)
5.Merged the NTRviewer folder with the old one.
6. Ran the program like normal and it worked fine

Thanks, I'll try using the merging method as opposed to setting everything up like new. Maybe that's why the commands won't work.

Have to wait until after work to see if this works, fingers crossed!

Can it get 60fps video? I feel like it'd be fun to get for Smash.

 

[cooroxd]

And one last question, has anyone tried streaming xenoblade or monster hunter 4? Or is it still too laggy?

Xenoblade runs at less than 50% speed when using NTR remote play, possibly because it uses the additional N3DS resources that NTR's also using.

I'm uploading a video of MH4U, i'll post it here.

UPDATE: here's the video:



20 fps stable on hunting and 30 fps on the lobby.

Much better than the Preview1 (~10 fps). If we can achieve another 10 fps for this game, it could be totally playable.
