So, I was wondering. I have a R4DS, and after i've seen some trailers of games, and television programs where they show in-game footage of DS Games without using a digital camera or anything, .. is there any way of recording both DS Screens with some piece of homebrew, or trick? Since I would like to know the best way for doing so.. maybe a DS Emulator that records both screens? I hope someone knows a good solution for this.

 

Companies who do video reviews and trailers/commercials are given a special cable from Nintendo apparently. I don't know of any Homebrew app that allows recording but I'm sure demo dumps are possible.

 

There was a topic about this a long time ago. Intelligent Systems (Yes the one's that helped make Paper Mario) made a official emulator for game company use only. They also made a device that can be used to record video off a DS screen.

 

Depending on your computer, it can potentially wreak havoc on your RAM. >_>

 

Too bad it'll never happen..

They have special modded DS games for that. I saw one during the Japanese Tetris DS tournament. It has a cable thing connected to the cartridge and it goes somewhere and ends up being displaying the top screen on a TV.

 

The other end is just a standard Composite or S-Video connection.

 

They just use a regular DV Camcorder with a Direct Sound Feed to the Camera using Stereo cables. It's a popular technique nowadays for do-it-yourself video capture for DS. There's a whole tutorial on how to get near perfect results on the speeddemosarchive wiki page.

 

You mean like the PSP can use a TV?

Yeah, that would be cool... However, the graphics in most 3D games would probably be screwed up if it was stretched to fit a 40" LCD Screen TV.

Or, it'd be impossible to play Elite Beat Agents, well at least while looking at the TV screen.

Nintendo use a modified DS called the Nitro capture unit. However, if you wanted to make one yourself, see jumbotron DS (http://home.comcast.net/~olimar/DS/jumbotron/)
