Nintendo announced back in January it was shutting down Miitomo on May 9th. I know, it wasn't very popular, and it's not really a "game", but I figure Nintendo's first smartphone app is worth some sort of archiving effort.

The majority of customization assets (clothes/wallpapers/flooring/etc.) are stored on Nintendo's servers and are downloaded to the app as needed. So once the app shuts down, all of that will probably disappear too.

I used a packet capturer to try and sniff out where the data is coming from. The model assets seem to come from zip files stored on "download-cdn.miitomo.com". ("api.miitomo.com" is another URL where... stuff comes from.) Here's some samples:

(Replace the "android" with "ios" for the iOS assets.)

I've tried manually downloading stuff by going through the numbers but, um... there's a lot. The shirt numbers alone go up to at least 1000. But a lot of those numbers just don't exist? For example, "headwear0066" through "headwear0099" don't seem to work... but "headwear0100" does... but other numbers going up from there don't... but "headwear0211" does... etc.

It'd be nice to be able to just crawl the whole thing, but I've gotten 403 errors trying that.

The textures are PVR 3.0, ETC1 encoded (via GerbilSoft). I managed to open them with something called PVRTexTool, but there might be something else out there.

Here's some random examples:

And here's some other random URLs I picked up:

manifest.json lists all the files the game downloads, including their MD5 hashes, so a downloader can be made to get all the files ever used by the game regardless of region or platform.

I actually possess such a downloader, ~~and I'm downloading the files as I'm writing the post~~ Got it downloaded. About 762MB of content and assets.

I'm don't really care about Miitomo (tried it a few times but I didn't get the appeal of it, despite logging countless hours on Tomodachi Life), but for the sake of preserving its stuff? I guess I can do something to not let this game be lost to history.

Nice. (Also, welcome!) I actually just found the manifest last night. It's quite helpful. There's also one for iOS:

http://download-cdn.miitomo.com/native/20180125111639/manifests/v2_20180405_3_ios/manifest.json

einstein95 parsed out the links and apparently tossed them into ArchiveBot, so... I guess they'll be appearing on the Internet Archive in some form.

I might download them too for the heck of it.

The files starting with "urls-gist.githubusercontent.com" are what you want.
