New DS hardware development kit
Toolkit developer SN Systems has announced the arrival of a new official DS hardware development kit. Want to put a webcam on a DS cartridge? Talk to these guys.
There IS a downloadable trial - but unfortunately this download is subject to the confirmation of your licensee status. Only official Nintendo registered developers may use our software, and they "security check applicants to ensure this."
I'm sure this disclaimer is just there to scare off the timid and if you explain that you simply want to "hack" the unit and open it to public innovation they'll send you the download key immediately.
