What is the best way to capture footage of of a ds

A capture card

I am not sure what is considered 'best' here but I'll give 3 methods to capture DS games.

Wii U VC if the game is available there. (Good quality + HDMI capture cards aren't that expensive)

DS Capture card (Good quality but quite expensive. I am not even sure if they're still available)

Or pointing a webcam / phone at your DS. (Best cheapest option to get started)

I'd like to know it too. My only option would be pointing a phone camera at my DS, but I don't know how to keep both screens visible and still be able to play without shaking my DS too much. I would play Resident Evil DS.

@WanderAgro How I fixed this is by building a stand from LEGO holding my DS up, this way it is easier to point my phone at both screens and without shaking the DS. Then I upgraded to the Kid Icarus Uprising Stand. Hope this will help!

@Seydie: Thanks a lot for your suggestion. I'll try it if I can.

@Seydie I did this and I might have a world record soon so thanks a lot

i just record my 3ds with my phone, it looks decent enough.
