Animal Crossing is an interesting game to me because of how little the series code has changed over time. The GameCube releases seems to have almost literally been the Nintendo 64 release recompiled against a different SDK for the GC platform (weighing in at only 27MB total for the GC release! An entire 1.4GB DVD for 27MB!), while the Wii and 3DS games, and seemingly the Switch one, are variants of the DS rewrite (seemingly the last time the codebase was scrapped and restarted).

I'd be really curious to know how similar the Switch code is. On the surface, the game seems to have been extended quite a bit, but I feel like a lot of it is just uncovering functionality that already existed in the codebase, e.g. the ability to place arbitrary items on the outside grid, I'm fairly sure the "engine" already supported this, and it was the way outside objects were implemented, there was just no interface for adding/removing them.

New Horizons used the standard internal game engine Nintendo deploys for most of their flagship Switch games, called LunchPak/LunchPak 2.

Which is crazy since (having played NL and NH for a combined 1500 hours) even the little, deep details carry on from New Leaf. If I didn't know better I'd say NH was using an evolved NL engine.

Hmmm, I wonder! My experience with this comes from doing some minor reverse engineering work on the Wii game back in my teens, in order to pass all the dialogue through Google translate, for great amusement [0].

My observation was the data structures/file formats were basically slight modifications of the ones used in other first party Nintendo games, primarily Mario Kart and Mario Party. So it seems like it's always drawn heavily from some internal SDK/engine, it's just not clear how much, or how much of that engine is saved between consoles.

Anecdotally, the DS and Wii (and ... maybe the GC? I don't remember now) used the same file format for the dialogue scripts, although the DS version was little-endian, and broke all my (terribly brittle) "tooling". The 3DS was totally different, and I ... Think the Switch was a variant of the 3DS format? It's been a hot minute since I've looked at any of this stuff :-)
