>>49453925 Basically when they're making a game they create scaffolding for things that might get built in the future. Along time features get added and removed, and shit that doesn't get used, just ends up being cut off, because of the way programming works it's all interconnected hierarchically so just ignoring a branch is a lot easier than removing it completely, because removing it completely means removing thousands if not tens of thousand dependencies all the other shit relies on, and nobody's gonna get to the end of making a videogame and then re-make it from scratch in a version without all the dummy/dead data just so some autists doesn't lose his shit.
For example, read those posts in the OP.
There is audio data, which pretty sure they juggle cries between games rather than re-making from scratch every time. And there's a single count value, a single number, for pokemon that have megas in other games. That means there's a tiny bit file and one solitary mathematical number, 3, or 4, in the value strings. that's a remnant megas data, it's not the same as "Has megas data" which OP said which implies mega forms are fully modeled, textured, animated, and implemented into the game, there's just no way to trigger them, no. There's literally no mega data, it's just a number where mega form would be (Probably there because of home/bank dependencies) and a cry, which is more than likely from just data transfer since all the mega cries combined probably take up less than a couple megs of storage space.
