Yes

--------------------- MERGED ---------------------------



Yes assuming both have the capability of dump/restore.

Great, I thought that I'd have problems because the save is a file for the whole switch and not for a single user

It is a 'device' save, but from what I've seen so far, there is nothing linking the save to the device (e.g. serial number). I have not actually tested with another device because I only have 1.

There's a really online internet verification, so anyone (even users with physical cartridge version of the game) won't play every event when s/he's offline.
Maybe someone can wireshark the traffic to their servers and make some bypasser for it, hmmm..

Unless I'm misunderstanding his words, SciresM is confident that it's just bcat data. Meaning once one console has it, it can be exported and imported to other consoles in the bcat save partition.

YOU JUST MADE MY DAY

 

[claussm]

Promising news for sure! I'm sure in very short order this thing will be cracked wide open.

 

[OkazakiTheOtaku]

Really, worst-case scenario is that we miss the Easter event and then have the method down for the next distribution. People were so pessimistic about the wild area data for Pokemon Sw/Sh and how it would be impossible to get that to work on offline consoles, and now it's archived and importable ~1hr after the distribution starts.

dude lol u just spoiled me dorohedoro lmao

 

[Ferrowolf]

Wait how do you get the wild area data

Ahahahaha someone thinks I'm worth mentioning. Thanks for sharing this screenshot. It's hilarious

I planned on backing up the save of my 'backup' game (on emummc), and transferring to the legit copy (on nand) when it arrives.

Is this going to even be possible (using JKSV)? Or immediately flag Nintendo servers?

I have backed up and transferred Checkpoint saves for a few games from emummc to nand, and it has never caused any problems.

A friend and I tried this over a year ago with MHGU download quests. They dumped their bcat for me and I loaded it into mine. I can't remember for 100% sure, but I don't think it worked. I only remember being disappointed for some reason. Ha.

The game dont show up for me for save transfer on the "legit" System Option. Very odd. Guess you have to use a Save Editor, which is a No-Go for Legit Consoles sadly. Otherwise you still risk stuff.

I guess I will nail down my stuff to NFC Cards for now =/

We can put our stuffs in our amiibo cards ? How many items? Can we put everything ? (items, bells, receipies...)

 

[0bvious]

JKSV can backup Animal Crossing fine. Will that backup even work if I move it to system nand? I guess it might treat it as another system and fail?

Here are some preliminary audio discoveries I've made...

OST Files (songs) are located in `romfs:/Sound/Resource/Stream` and are in Nintendo's new-ish standard `DSP 4-bit ADPCM` codec, in a `bwav` container.

- These can be decoded/played/converted to standard formats in VGMStream
- These cannot be *en*coded with any standard software I've found (but I have found a way! writeup soon when I do some more testing)
- It doesn't seem like you have to worry about encoding to the proper bitrate. The bitrate is dictated by either the codec or the container. It looks like the formula for bitrate is `x * 219` where `x = # of audio channels`

In terms of in the context of AC:NH specifically....

- The `live` versions of the songs (KK Slider), they are single-channel (219 kb/s)
- New OST songs are dual-channel (438 kb/s)

Sound effects are tricker at the moment; they are packed into `.bars` archives in `romfs:/Sound/`
At the moment there is no clear way to extract what I assume to be more `.bwav` files from the archives.

To be clear, at the moment I have a method for converting arbitrary files into `.bwav` but I can't get the metadata right at the moment and I don't know if they work on the actual game, as I don't have my console accessible at the moment. But this is what I know so far.

Is there a way to extract the models from the game? After extracting the SZS/ZS files the BFRES file seems to be unreadable. Tried it with UWizard and Kuriimu.

Switch Toolbox works, and you can export to .dae

Thanks for your quick response!
The Batch export models one doesn't seem to work. It tells me it extracted/batched successfully but the folder is empty.

Sorry if this was already asked, but can anyone confirm if it's ban-safe for legit switches if you play with a hacked one in local wireless and trade items between them?

Can you test it and lets us know ?
