The title pretty much explains it all - I want to be able to take screenshots from my DS, but haven't been able to find out whether it is possible and affordable.
Hate to break it to you, but it's in the $3,000 range.
There must be some means of getting video output from a DS, because G4TV and GameTrailers include gameplay video in their reviews, and there's no way they're playing the entire game in an emulator. And they're definitely not just filming the screen, because you can see effects of the stylus without seeing the stylus in front of it.
It's possible they have special hardware from Nintendo, or they may have in-house modders crafty enough to figure out where to solder a video cable to the motherboard. You might want to try asking on the GameTrailers forums how they record their videos of DS gameplay.
I also found this article on Nintendo DS on your TV, but it's really old (August 2006) and it says in an update that the device was a prototype that was never actually sold.
Yes, you can. Try using nds-bootstrap or TWLMenu from GitHub. nds-bootstrap is a bootstrap program to boot NDS roms that can be dumped from your cartridge. TWLMenu is a menu that can be used on a flashcard to boot these NDS roms. Check the wiki for the way to install and setup this. When TWLMenu is installed, you can open the nds-bootstrap menu to make a screenshot. Press
SELECT to open this menu. Now click on
Take screenshot... And then select the right VRAM bank and press
a. Whola! Now a screenshot is made. Then you can find the screenshot in:
fat:/_nds/nds-bootstrap/screenshots.tar On the flashcard. Or try the app on 3DS if you have one.
