Homebrew Is there a guide to decompile an official theme and turn to custom?

[RemixDeluxe]

I'm not asking where to get the official themes, I just would like to know if what I'm asking for is possible to do so I can use with menuhax 2.0

If I remember correctly, the MenuHax installer not only has a way to inject your custom theme into the system but it also has a way to extract the current theme from your system. You could use that to extract official themes from your 3DS system, if you paid for them and have it, that is.

So what your saying is theres no program or anything to decrypt them but only by extracting it yourself if you own it?

You can get them on that iso site.

There's a program called YATA+ and many other similar programs. It is what allows us to create our own custom themes. Even though I haven't tried, I am 99% sure that program will be able to open the extracted theme from your system.

I can confirm that YATA+ can do exactly that. Just dump the body_LZ.bin and open it in YATA+, boom

there might not be a program SPEICIFICALLY to decrypt themes, because themes are just like another other content/dlc downloaded from eshop etc, you decrypt it just the same as decrypting a game or an update. themes kind of just 'dlc'.
if you don't know how to decrypt eshop content, then that is what you should be looking for

Did you forget to link something? Otherwise your last sentence makes no sense.

i didn't say 'this' (and then post a link) - i meant that you should be looking for 'how to decrypt eshop content'
there are a bunch of threads here about it i am sure
makes sense to me!

my bad, I thought you were trying to show me something. I thought the only way to install DLC is with .cia files anyway which is out of reach from 9.2+ users. Sadly I'm on 10.1

 

[phalangery]

Like I said, use YATA+.
Themes are gonna come in a body_LZ.bin. If you open that file with YATA+, it will show you the top screen background, the bottom screen background, the BGM, the sound effects, etc. You can then save them separately and/or mess with them to your heart's content.

EDIT: I feel like either I'm not getting it or you guys are making this way too complicated. If you can run homebrew at all, you can dump your current theme with yellows8's homemenu_extdata tool. From there it's literally just as easy as opening that file in YATA+. I did this exact thing with the DLC Shantae theme

ah ok. to decrypt YOUR OWN content/any thing encrypted, you need to be on 9.2 or below. well there is the braindump thing, i only read a little about it, maybe that will help you decrypt content above 9.2.

but, you might be able to find online an already decrypted version of the theme you want
but if you cannot, then you would have to get it decrypted

he is asking how to get this body_LZ.bin

That's easy, use yellows8's homemenu_extdata tool, it comes with smea's homebrew starter pack

Is it theoretically possible for 9.2+ users to install decrypted DLC then?

You can install the regular menuhax then switch to an official theme off the theme store and it will still work, I'm currently running it with an MH4U theme off there. The readme specifically says the only action you can do and not lose menuhax is switch to a DLC theme.

You will lose it if you switch to another default theme though, and I don't have another theme to test if switching to another allows it, I'm guessing you'd have to reinstall it first in order to switch again.

homemenuext data (remember this?) extracter would be my best guess but we shoudlnt be going as low to pirate themes.

Why are you in this topic then? Please don't persuade me to not do something because it makes you uncomfortable.
