Homebrew HzMod - old3DS screen streaming

[CyberTails]

I have absolutely no idea why it would crash :/ Low on free RAM? Out of VRAM? What CPU?

I'm going to try to update Windows 10 and see if that helps. I'll give you further details

UPDATE: I just update to Windows 10 1803 and the software loads and works now, ty (How do I take advantage of the New 2DS XL's Feature for HzMod?)

No need to do anything, new3DS checks are inside HzMod which should run stuff on Core3 (I hope).

Thought I test this since there was talk about it on the Snickerstream thread and it runs okay-ish on the N2DSXL if you drop the quality down to 50%, just curious if there is any way for performance to be on par or better than NTR in the future or is this the best it can get without hacky workarounds?

Well, for new3DS I could definitely do some optimizations, but this is sadly old3DS-optimized, and any change to the code WILL break old3DS compatibility, which would defeat the purpose of this thing. But yeah, since you can't map physical memory to your process, it's not possible to have better performance than what we have. NTR runs inside nwm (Nintendo Wireless Module, aka. the wifi (and Ethernet) sysmodule), AND it runs its code inside kernel mode when compressing the frames, so it doesn't need to map physmem to itself because it can already access physmem instead of having to use IntrProcessDMA (which requires time to copy data and RAM to hold the duplicate data).

Ah, so that's why NTR get's such good performance but is somewhat buggy to use, I had many times where it would just not work and I had to reboot and enable it again, I did find HzMod to be much more stable than NTR with the only issue is slightly poorer performance but I'm guessing having 2 versions to maintain is a lot of work.

It's pretty amazing you were able to get this much out of the o3ds despite it's hardware limitations.

Not having luck getting this to play nice with luma inputredirect, I tried running Hz then running input redirect and it works but Hz shuts off (I assume it does because the teal led shuts off) I then tried launching Hz again then my 3ds crashed. I included the crash dump and Hz log.

When I try running input redirect with HzMem input redirect fails and spits out an error code.

How do I compile this for Linux?

I already installed libsdl2-dev, and even so it tells me that a bin2c command is missing, so I installed hxtools, and even then it tells me an error.

What version of devkitARM do you have? The bin2c command comes from a devkitARM installation.

Oh, I thought DevKitARM was not needed, because I was compiling it for Linux not for 3DS, right now I install it.

Yeah, I have devkitARM/bin permanently (~/.bash_profile) in my PATH, so that explains everything.

Now install devKitARM, what should I install with the devKitARM pacman?

 

[Sono]

Oh fuck, I forgot about pacman... well uh, I have no idea. I downloaded my devkitARM package from Sourceforge. It's highly discouraged here to use old versions, but you could either grab the devkitARM_r45 package from Sourceforge or compile bin2c.c from the devkitPro Github.

You just need the regular toolchain to compile for Linux.

 

[yonaikerlol]

You just need the regular toolchain to compile for Linux.

I already have the devKitARM installed, devKitPRO, with all the packages from the pacman repository: 3ds-dev, I have installed the bin2c compiled since the last version (1.1).
In addition to the basics, GCC.

The error apparently gives it to me because I do not have the turbojpeg installed, since from the main repository it can not be compiled (or at least I did not find how).
So just copy the turbojpeg.h library to the folder soos of HorizonM, and I compiled that part (which I could not before), but now I got stuck in it.

In addition to the .h which is just the header, you also need the library itself installed on the system.
In the turbojpeg source you should be able to run the usual ./configure (or a variation thereof), make and make install and it should all be taken care of. That's usually how it goes. But it will likely have more specific install instructions.

libturbojpeg has a ridiculous package name in apt; something like libjpeg-turbo or something like that... just use apt-cache search to find it

He uses pacman.

Also, I just realized... how did you get HorizonScreen source? It must be a super ancient version which doesn't even work properly with newer builds. If I survive then I'll hit up my Linux installation in a VM and figure out how to build it.
