The only screen recorders for old and new 3DS such as NTR and HzMod work by streaming the 3ds screen to a computer, where it is then recorded, Why couldn't you just record directly on the 3ds? In all the videos, the 3ds seems to be running at a perfectly fine speed while streaming to the computer (not referring to the streamed framerate but the actual 3DS) so if it doesnt slow it down, what's the point of not having a local screen recorder, wherein you start it up, begin the recording, record, and end the recording wit a button combination? The video file could be saved to the program folder. So my question is; Why is this not a thing?
Homebrew How come there are no local screen recorders?

yes but like. for ntr. the 3ds still has to send 1 image per frame to the pc right?
well couldnt it just save each image and make a video instead of sending it away to stream
@Stabnormality the O3DS is far weaker, and the N3DS only has a *Slightly* Faster ARM Based CPU, the same task a modern Desktop CPU could do in say a few clock-cycles would take much longer on the 3DS's (now rather rapidly aging ARM CPUs). there just isnt enough power behind it to both Record/Stream & play games, (NTR for N3DS has its limitations, which can be seen hard if you try streaming while playing VC Games )
2 big reasons this works far better on the Switch,
Much more powerful SoC/CPU than the 3DS + it was an core feature of the Hardware the switch was based on, Nvidia Shield)
AND its streamed over a much faster Medium ("Sys-DVR" streams over both it's USB , and switch's compared to the 3DS, vastly superior Wifi hardware+ it hijacks functions allready existing in the Switch OS, "Horizon")
No such functions exist on the 3DS, wasnt based on a device that could, and hasto be Kludged into doing it. thats alot to ask from hardware that's essentially 9 years old at this point. hardware that was designed to be what it was from the ground up*ONLY* to play games

Probably because the video data streamed to the computer is using some custom simple codec/compression or is not compressed at all but to save a video file on the 3DS you would have to encode the video into a standard video codec and then constantly write the file to the SD card while the game and other things also need to have to access it
But 44670 already had a beta ntr that saved 30 seconds to the sd card.

Then I guess it is possible but it's still only 30 seconds and doesn't it slow down or stop the game when recording/saving?
It seems to max out the sd card when saving. Game audio sometimes cuts out. 30 seconds is either because that is somewhat typical for a console short recording or because it needs to pre-allocate space or just because it is unfinished.
Well then if you wanted to record for more than 30 seconds you would have to write the video data to the file while still recording and playing the game and at best that would cause much longer load times in games
Is the source code for this available anywhere?
