What a nice surprise to see this on the HN front page! I was involved with DSLinux for several years. I maintained nightly-ish builds that I hosted on my website. I don't think I ever contributed any code, as my C and system programming skills were still rudimentary at the time, but I did a fair amount of testing and helping people in the community.
Most of credit for the amazing work that made this possible goes to a few individuals, in particular Malcolm Parsons (pepsiman), Stefan Sperling (who later became an OpenBSD developer), and Amadeus: http://dslinux.org/wiki/ContactingDevelopers.html
I sold my Nintendo DS since then, but I still have somewhere the Supercard that I would use to store and boot Linux, which looks like this: https://wiki.gbatemp.net/wiki/File:SuperCard_CF_V2.jpg
