How to get APK out of bluestacks? Rise of Berk. | The Spriters Resource | Page 1

#

I am trying to get models from dragons: rise of berk. I successfully have it running on bluestacks 4 and the models I want are RIGHT THERE. But any separate apk I download has no models at all! They likely load in when the game is booted up! When I ran the non-bluestacks one through studioassets, it just said "no unity asset could be loaded" which im worried something is wrong with it, because the APK I gave it had audio assets and it did not even show those. (Does it usually show all assets?)

Is something wrong with my studioassets program that its not even reading any audio assets?
How do I get an APK out of Bluestacks and back on to windows? I tried "export to windows" in bluestacks media manager, but it said "cannot copy files" 😭

#

You have to compress it first (for example .ZIP) and then you will be able to.

#

potent kiln 2. You have to compress it first (for example .ZIP) and then you will be able to...

Oh? How do I do that in bluestacks?

mental heath Jul 5, 2024, 4:53 PM

#

So I got the file to zip using astro file manager on bluestacks.......now to figure out how to move it back to my actual desktop.

potent kiln Jul 6, 2024, 1:09 AM

#

Using the media manager's "Export to Windows' feature

#

If that fails there is a shared media folder called "BstSharedFolder" you may be able to use instead.

mental heath Jul 6, 2024, 5:04 PM

#

potent kiln If that fails there is a shared media folder called "BstSharedFolder" you may be...

I was able to move it out, but I had to import something (random file) from windows in order to make the folder appear in asset manager. Now I have two different folders from the app, the unzipped APK I got from bluestacks, and another that only has the cache in a file called no-backup.

#

But when I try running them through asset studio, the greenbar loads about half way and then says "no unity file loaded".......I wonder if that means they are encrypted 😭 is that normal?

potent kiln Jul 7, 2024, 12:25 AM

#

I won't be able to tell unless you upload some sample files.

#

(Note: Only a few files, not the whole thing)

mental heath Jul 7, 2024, 2:36 AM

#

potent kiln I won't be able to tell unless you upload some sample files.

Upload files or upload pictures of the files? I wouldn't know which ones would be useful information. Heres pictures in the meantime

potent kiln Jul 7, 2024, 2:36 AM

#

That's kinda funny, but its not helpful lol

#

I meant like take some of those and upload them here or to another site like google drive

#

But not everything since its against the rules to link to an entire game's resources here

mental heath Jul 7, 2024, 2:39 AM

#

Lol

#

Would one of the cache ones work?

potent kiln Jul 7, 2024, 2:40 AM

#

For unity games the expected file type is usually something like .bundle or .asset or .ab

#

Are any of those in there?

#

It is also possible to have files like this instead

#

It is still possible to have others of course

mental heath Jul 7, 2024, 2:42 AM

#

Searching apk......no.

#

Theres a file labled assets it has music .wav files

.dsb files .dhr files

potent kiln Jul 7, 2024, 2:44 AM

#

I haven't heard of those

#

Did you try loading the entire apk file?

mental heath Jul 7, 2024, 2:44 AM

#

Yeah.

potent kiln Jul 7, 2024, 2:45 AM

#

I'll look at the game myself and see if I can figure it out.

mental heath Jul 7, 2024, 2:45 AM

#

FOR REAL?!

potent kiln Jul 7, 2024, 2:45 AM

#

Geez lol

potent kiln Jul 7, 2024, 2:46 AM

#

No guarantees!

mental heath Jul 7, 2024, 2:46 AM

#

Just someone else who knows what they are looking at more is great

potent kiln Jul 7, 2024, 3:16 AM

#

So i guess the files are these dsb , dab, and dhr files but I have no idea what they are

#

Hey this looks promising, same company too! Looking at the files in a hex editor reveals LPKG at the beginning of every file

mental heath Jul 7, 2024, 3:36 AM

#

Wow

potent kiln Jul 7, 2024, 3:36 AM

#

So it did work, kinda

mental heath Jul 7, 2024, 3:37 AM

#

~~What is lpkg?~~

potent kiln Jul 7, 2024, 3:37 AM

#

Some kinda compression

#

This is the result

#

Pvr is some kind of texture format, an example

mental heath Jul 7, 2024, 3:37 AM

#

!!!!!

potent kiln Jul 7, 2024, 3:38 AM

#

As for models I don't know

#

It could be buried in this avalanche of .dat files

mental heath Jul 7, 2024, 3:38 AM

#

What hex editor? How did you decode them?

potent kiln Jul 7, 2024, 3:38 AM

#

By the way all these files is just 1 out of a billion dsb/dhr/dab files lol

mental heath Jul 7, 2024, 3:39 AM

#

There could still be models buried somewhere in there?

potent kiln Jul 7, 2024, 3:39 AM

#

Perhaps

#

I only looked a bit for the texture format

mental heath Jul 7, 2024, 3:39 AM

#

Would the asset studio pick them up?

potent kiln Jul 7, 2024, 3:39 AM

#

No

mental heath Jul 7, 2024, 3:39 AM

#

Wah

#

Thats a big step forward

#

......how would I replicate it?

potent kiln Jul 7, 2024, 3:41 AM

#

Well anyway for this you download quickbms
Download the ludia jurassic park bms file
Load the bms in quick bms and then the matching dsb/dab/dhr files

#

I can record this process if it will be helpful

mental heath Jul 7, 2024, 3:41 AM

#

Please that would be amazing.

#

How did you get the rcmcache too?

potent kiln Jul 7, 2024, 3:43 AM

#

That may be a little more annoying

#

It requires root

mental heath Jul 7, 2024, 3:43 AM

#

Hhhhh no android

potent kiln Jul 7, 2024, 3:43 AM

#

So I was able to get it using the nox emulator

#

Other than that I don't know how you would

mental heath Jul 7, 2024, 3:44 AM

#

I'll see if bluestacks can and if not, i'll just try nox!

potent kiln Jul 7, 2024, 3:44 AM

#

Nox is easy because having root is just a checkbox

mental heath Jul 7, 2024, 3:45 AM

#

And then you just import it to desktop like normal?

potent kiln Jul 7, 2024, 3:45 AM

#

i copied the folder to downloads since you can open it on desktop

mental heath Jul 7, 2024, 3:46 AM

#

Did you have to open the app or is that data all just from apk?

potent kiln Jul 7, 2024, 3:46 AM

#

Give me a second

#

The location is root/data/data/com.ludia.dragons/files/RcmCache

#

mental heath Jul 7, 2024, 3:48 AM

#

Bloomin hell, downloading nox asap

potent kiln Jul 7, 2024, 3:48 AM

#

You can download es file explorer to easily copy this to the downloads folder

#

You must enable root though or you wont be able to

mental heath Jul 7, 2024, 3:49 AM

#

I did something similar in bluestacks with astro file manager

potent kiln Jul 7, 2024, 3:49 AM

#

Which ever you prefer as long as its able to do it!

mental heath Jul 7, 2024, 3:50 AM

#

So you got the little dragon images without a file viewer.

mental heath Jul 7, 2024, 3:51 AM

#

Thats the one you downloaded?

#

Damn before I even asked

potent kiln Jul 7, 2024, 3:52 AM

#

Is the question not implied? thinkio

mental heath Jul 7, 2024, 3:52 AM

#

Does the game load the cache when it loads or did I just wrongly assume that?

#

I thought it had NO assets until loading 😭

potent kiln Jul 7, 2024, 3:55 AM

#

Uh Idk

#

When I downloaded it it downloaded roughly 800 mb of data and the rcm cache is roughly 800 mb

#

So I would assume this is the data

#

Or I am misunderstanding the question

mental heath Jul 7, 2024, 3:57 AM

#

Did you start up the game?

#

Is it possible the models are still loaded in after loading up

potent kiln Jul 7, 2024, 3:58 AM

#

Whatever for now I'm focusing on these files since you wanted to know how to unpack them

#

quick bms https://aluigi.altervista.org/quickbms.htm

Luigi Auriemma

mental heath Jul 7, 2024, 3:58 AM

#

Sorry yesse

#

Nox downloaded

Downloading game now

potent kiln Jul 7, 2024, 3:59 AM

#

the script (note: automatic download) https://aluigi.altervista.org/bms/jurassic_world.bms

#

I already listed the texture viewing program and how to get the files (scroll up for that)

mental heath Jul 7, 2024, 4:01 AM

#

Yesssss thank you

#

Im gonna get to downloading and messing with these.

potent kiln Jul 7, 2024, 4:04 AM

#

How to unpack the files

#

For a little while I was wondering if all of this was just ui elements, but no there's 3d model textures too, along with misc things like audio (and quite possibly models)

mental heath Jul 7, 2024, 4:11 AM

#

Im EXCITED

#

Im sorry you had to do so much digging

#

BUT STRAIT UP MAKING MY DAY

potent kiln Jul 7, 2024, 4:12 AM

#

No worries

#

I wouldn't do it if I didn't want to

#

I find it kinda fun

#

But don't get excited for me finding the models or extracting them because I probably won't be able to

#

In that case you'd have to hope someone else could figure it out

mental heath Jul 7, 2024, 4:14 AM

#

How so? Would there be another program needed to find them or is there just.....a lot to go through.

#

Because if theres just a lot to go through I fully intend to dig.

potent kiln Jul 7, 2024, 4:15 AM

#

My knowledge of 3d model formats is extremely small lol

#

I only deal with models after they've been extracted, see?

mental heath Jul 7, 2024, 4:16 AM

#

Ah. So it would be finding out what format they are in and asking around for something that can view those.

potent kiln Jul 7, 2024, 4:16 AM

#

Though if I can find some evidence of it, you might be able to convince someone to look into it

#

It's more likely someone would if there's less work to do

#

Not guaranteed though!

mental heath Jul 7, 2024, 4:19 AM

#

Find evidence of models in a funky format, heard!

#

You would be ok if I ask more questions later on after I get all this stuff downloaded yeah?

potent kiln Jul 7, 2024, 4:21 AM

#

Okay!

#

I'll try and answer if I can

mental heath Jul 7, 2024, 4:29 AM

#

Ok so I got the file explorer and root is on, and I copied it into downloads but theres no rcmcache

Does it do it automatically when root is enabled?

potent kiln Jul 7, 2024, 4:31 AM

#

If root is enabled you should be able to explore those files

mental heath Jul 7, 2024, 4:49 AM

#

Gonna watch a video on how to get to root on file explorer.

It did not work. Turned on show hidden files and root explorer on es file explorer and still don't know how to get to root folder.

MORE RESEARCH I FOUND IT had to go home directory and /

potent kiln Jul 7, 2024, 5:31 AM

#

Great!

mental heath Jul 7, 2024, 8:31 PM

#

Got to the tacent viewer and got to see some textures for decorations and character models..... any idea on what files it can and can't open? .dat could be anything, right? but I get some errors on some of the other ones too. "Error: no such file in directory".

mental heath Jul 7, 2024, 11:35 PM

#

I kinda dumped every single file that had "dragon" in the name from rcm cache, and made a discovery. (It took like a half hour to transfer to desktop 😭)

The files are separated by species! Lol.

I even found the texture of the model im targeting.

potent kiln Jul 11, 2024, 3:40 AM

#

@mental heath Yo! I managed to find and analyze a model file

#

I did tell you I have little knowledge in these things, but this format is straight forward as model formats go

#

And don't get excited for a automatic model extractor, I set this up manually by hand in model researcher

#

This is the model file

📎 000000ba.dat

mental heath Jul 11, 2024, 3:44 AM

#

I THOUGHT IT WAS A DAB

potent kiln Jul 11, 2024, 3:44 AM

#

As for it is formatted, at the beginning it is vertex/normal/uv and then face indices

#

No rigging data in the file? (not that I'd know how) so it has to be stored separately

#

This is as far as I can go..

mental heath Jul 11, 2024, 3:45 AM

#

textures and model is all I could ask for

#

I do have one last need of you

#

Please teach me how.

potent kiln Jul 11, 2024, 3:47 AM

#

Oh, that's quite an ask, given I can only sorta understand it myself

mental heath Jul 11, 2024, 3:47 AM

#

model researcher?

potent kiln Jul 11, 2024, 3:47 AM

#

It is a program

#

For analyzing model formats

I was just about to ask the form tomorrow

#

Oh and I need to find out also, is this file a model?

potent kiln Jul 11, 2024, 3:49 AM

#

Anyway as to not lead you completely in the dark, here is the tmr file for the above model file

#

Load the model and then load this template

potent kiln Jul 11, 2024, 3:50 AM

mental heath

you need the corresponding dhr and dsb files and then unpack the files with quick bms

mental heath Jul 11, 2024, 3:51 AM

#

I found them as well I think.

#

and the resulting pool of .dat files is where the models are held? Lol Im so sorry for asking so many questions you have amazed me

potent kiln Jul 11, 2024, 3:52 AM

#

Yes

#

You can open up these dat files with a hex editor to examine the contents

potent kiln Jul 11, 2024, 3:52 AM

#

potent kiln https://mr.game-viewer.org/tutorial.php

Refer to the guide here

#

You can also view the model file I linked for a better idea of what to expect

#

It will be very confusing, just so you know..

#

So don't give up easily!

mental heath Jul 11, 2024, 3:54 AM

#

I certainly will not! I will play with this a lot tomorrow and do a lot more research!

#

Would I still be able to ask you questions if I get hung up on something though? 😭

potent kiln Jul 11, 2024, 3:55 AM

#

Anyway you can ask me for help, I'll help if I can

You said face data is at the bottom? While guide's face is at the top. Oh boy. Any idea how to tell where the face- HOT HELL

#

YOUR TEMPLATE WORKED MAGIC

#

I JUST HAD TO ADUST THEM SO THEY DIDNT OVERLAP OR GO OVER

mental heath Jul 11, 2024, 10:29 PM

#

The texture is flipped when I export but I can learn to fix that

mental heath Jul 11, 2024, 11:14 PM

#

:) WAHOO!!!!

potent kiln Jul 12, 2024, 6:47 AM

#

Yay!

potent kiln Jul 12, 2024, 12:03 PM

#

And I guess you don't need it anymore, but the face indices have a very uniform look to them so they are easy to spot

#

Here the face indices start right after the last uv coordinate

#

The type is short (you can see that if you view the template)

mental heath Jul 12, 2024, 3:33 PM

#

Ohhh I see it a bit! I just replicated where I saw it began on the template!

Im going to make sure everything right with the extracted model, run it through the checker, learn to make some icons and try to upload to the resource.

If all goes well I'll dig out more dragons!

Thank you so much for showing all of this! Its been a dream completed!

potent kiln Jul 12, 2024, 3:36 PM

#

You dont even need to look for it anyway

#

assuming all files are arranged the same way, the end block of the vertices will be the beginning of the faces

narrow shuttle Jun 23, 2025, 12:29 AM

#

Oh my god this thread is a lifesaver

narrow shuttle Jun 23, 2025, 12:10 PM

#

Sorry for reawakening this but I really need help . Ok so I did the steps above until I decompressed the .dab file for a dragon to 1350 .dat files (and other sound files) now how do I know which one of those holds the model and if I found it how do I get it out in ModelResearcher

#

Without a template of course

narrow shuttle Jun 23, 2025, 2:35 PM

#

Also an update on how to get the bones as well for animating would be great

mental heath Jun 24, 2025, 3:11 PM

#

Ah, you find the right file by sorting by size, and picking which one you want thats a .dat. Titans usually largest, followed by any premiums, then the regular dragon, and then baby.

Or just check its the one you want by setting a few thousand verts and clicking render. It will give you a shape of red dots to look at, and check if its the right shape for your dragon (make sure its not split or on its side)

Then check hex view, and probably load a template. It just needs adjusting to the right amount and end points (and will likely need extended much more than what a small gronkle takes) make sure theres no overlap and that the faces (green) don't go past the end. Find where the verts, Uv and normals end, and the faces begin (as pointed out above, faces are uniform, usually with 0 in every other space). Also for these dragons, are exactly 8 spaces away from the last line of FFFF. It should fit perfectly.

#

I still don't know how to get bones or animations. Also the rise of berk models are kinda seamed? Parts are not actually connected, so might have to be messed with to get a different rig to work. I did find a folder called dragon animations global! But its more dastardly .dat files that of course the model researcher can't research (because its not models).

potent kiln Jun 26, 2025, 12:11 PM

#

I was thinking about looking at the models again, but unfortunately I can't get the game working in Nox anymore.
It won't let me accept the prompts to start the asset download.

#

Looking at the old file I shared before, the only things included are vertices, normals, UVs, and quite possibly vertex color (the "FFFF"s)
