>>42604348>>42604412You can actually.
CTRPluginFramework allows for something similar to
>>42604374, its menu has a button to make several screenshots for a few seconds, which you can then use to make a gif.
That's obviously not a great solution though. You can send your video over wireless using NTR (or maybe some newer homebrew, I'm not sure if newer options exist) to a program on your PC and record from there. Quality varies between game. This method doesn't send the audio, you always need to use a cable. Of course a capture card is the best option, but that seems to work well.
