Advent of Code on the Nintendo DS
Solving AoC on the DS with Rust.
This post is long, verbose, and explains a lot about things that aren't relevant because this was written in tandem with developing the project and is meant to show everything I learned on the way. It's hard to get an actual source on this, but various comments spread across the internet talk about how most code on the ARM7 was heavily restricted by Nintendo, thus most of the power of the secondary processor goes entirely unused. But those are all topics for another day, because this post is already very long and implementing more complex features such as cart transfers or extended graphics is an entire entry's worth of detail in itself.
