Joat from the new Nintendo DS homebrew wiki
has accessed the DS touchscreen and shows us his "hello world" - a tech tutorial classic.
A video is also provided.
This cinches it - I'm ordering parts to build my own Passme passthrough pronto. Let's hope that Joat continues his good work and posts plenty of instructions on the wiki! You should too order your parts, too. I'll post on my experiences and you reply. We'll do it... together.
Thanks to Charavel Olivier and Darkain's blog for the scoop...
