GameBoy Emulation

[Spectere]

I need to check out that Advent of Code stuff at some point. That would be a good way to either brush up on my Objective-C (or learn Swift, for that matter).

Couldn't be worse than learning modern C++ by writing an emulator (though at least I went into writing Plip with a reasonably solid knowledge of C).

They are quite fun. The way they integrate a story line and present the problems is excellent. It's often very clear what they want you to do (unless you flat out do not know the algorithm or data structure they expect you to use). And the way they often build upon earlier solutions for later problems feels good, since you aren't always starting from scratch for each problem. Plus theres often a lot of opportunity to go above and beyond what they want if you feel like doing something neat.
