I very fondly remember this project when I was growing up too, and I credit it with sparking my interest in kernel development.

When trying to port some industrial control software to DSLinux, I ran into some bugs around how the SLOB allocator behaved under memory pressure. One of my patches landed upstream, even though SLOB is deprecated now. Still, as a kid starting out in the embedded space, it opened my eyes to the joys of hacking around with homebrew.

Fun fact: a modded DS still powers a large part of my local observatory's equipment.
