In case anybody here is interested, a few years ago I put together a similar (albeit far less comprehensive) resource on original PlayStation programming [1], exploring the GPU, geometry coprocessor and serial I/O hardware step-by-step with plain C examples. I'm planning to extend it with more examples covering audio and CD-ROM access next, but haven't yet had the chance to do so.

Great resource! But a lot of it is very old. I recently discovered this open source ds cart[1] and an alternative SDK[2] to devkitPro. Both were used in the development of a demo[3] released at Revision this year.

If you want an architectural overview of the DS, this is a fantastic overview: https://www.copetti.org/writings/consoles/nintendo-ds/

Making homebrew for the Nintendo DS was how I got into programming in the first place. Devkitpro was too confusing for me back then, so I used something called PALib, essentially a pretty hacky library built on top to make it "easy".

Nice community at the time though, I made a pong clone where the main selling point was that you could switch between different "themes", and a bunch of people contributed some really nice custom ones to be included.

This is exactly what I've been looking for recently. Me and my partner have gotten into reshelling and jailbreaking old handhelds, and we both have DSis that we enjoy, and I've been thinking of homebrewing some stuff for us

I had a go at setting up the devkitpro stuff and building a demo that I run on my DS. It’s surprisingly easy to do and kinda neat.

Damn this is some legit information. I've looked around for some more recent information regarding modding and shelling, any tips other than the ones listed below?

Thx
