Homebrew Official Citra - New 3DS Emulator

[zecoxao]

Can someone direct me to how to decrypt cia files as i have a cia file that is region free but i gather it is still encrypted hence why it wont run on citra

you can extract the cia by using makerom tool

Not looking to extract the cia i have the cia it is just encrypted need to decrypt it

makerom -ciatocci <cia_here.cia>

Citra crashes when I'm trying to load Cave Story 3D

File name of it is "ctr-acvp.3ds" if anyone knows what to do

You need one or the other to decrypt ROM images unfortunately. Google the XORPads for your specific game- you'll find them eventually. Hopefully neobrain will make Citra compatible with encrypted ROMs in the future, so this will be a non-issue.

Unfortunately, Citra will never be compatible with encrypted ROMs until the bootrom section of the 3DS processor is extracted and dumped, 'cause only that will contain the 3DS's common key, which is necessary for decrypting ROMs to be readable, and is a very important function in generating xorpads with the program.

Also, it'll be even harder for creating an emuNAND on Citra, 'cause the NAND key is unique to each 3DS console. Which will mean it'll only be possible if there was an easy way of extracting the bootrom from the 3DS processor, which will probably never happen until 20 years later. Or if someone decrypted and dumped the decrypted NAND onto the internet.

Or just not encrypt it at all. Getting a decrypted NAND is also possible and building one from scratch is possible too.

Would it be possible to run Citra on an Android device by installing Linux on it, and then running the Linux version of Citra on it?

As for the possibility of it not running it well, the Galaxy S6 seems pretty strong with an 8-core CPU (technically two 4-core CPUs), a 1440P screen, and 3GB of DDR4 RAM. This is the phone I'm getting in a week or two.

One last question, is Citra currently a single-threaded, or multi-threaded process? If multi-threaded, how many cores can it take advantage of?

No.
Also Android is already linux.

No he could using a current build, he'd just be sitting at a nice 1fpm.

Best wait for actual android support, I think the android version will come along much sooner than android running a virtual Linux emulating a 3ds full speed... on a phone.

So Android running Linux has a performance loss (compared to a Linux desktop of similar power), or are you just talking about the fact that a phone is unlikely to run a 3DS emulator well?

Linux VM on Android will have an overhead.

Also #1000

The former. Linux desktop on android is at the level of emulation in speed and performance, so it'd be an interpreter emulator with software rendering running on an emulator on a phone.

I'd be surprised to see a gameboy emulator running at full speed on android-linux. Or a calculator.

Tl dr very very very slow unless you own a phone from 15 years in the future right now. You'll definitely have to wait for an apk version.

It would be possible, however there wouldn't be too much point except for proof of concept as the speed would likely be terrible. I know Dolphin Emulator worked on Android via Linux before the actual Android port was released, so why not this? Citra already is able to compile on ARM AFAIK, so with a bit of setting up, you could make a build and run it. Also, contrary to what many people seem to believe, it is not emulation. Linux will actually be running on Android, however it won't be running as fast as a desktop with the same power due to the Android OS and all its processes running in the background, and unless it's been fixed, there is no hardware acceleration. You do need root to do this, however there is an application called Debian noroot which runs Linux applications without root, but it's just a compatability layer, basically like Wine. If Citra can run on Debian noroot, it will get lower performance than the root method. If you want to try this, here's a link to the Dolphin guide. This is the probably the easiest way to do it. Of course, instead of compiling Dolphin, you'll want to try and compile Citra.

Also, I'm pretty sure Citra is only single core ATM.

CITRA NOW RUNS POKEMON MYSTERY DUNGEON!!!!!!!!!

 

[Tjessx]

Even with an apk version there is no phone strong enough to emulate 3DS, maybe in a few years.
Definitely not a Samsung phone.

 

[Pink Gold Peach]

Can someone help? I have OoT3D.cci and when I try to run it in Citra, it crashes

"Defintely not a samsung" but they have the most powerful phone to date! (S6).. And considering some dolphin games can run full speed on the K1 Tablet. Im sure when citra hits decend speeds some tablets could handle it.

Even though I'm personally not a fan of their phones, there's nothing specific about them that would prevent them from running a 3ds emulator over any other phone out there. According to this page: http://www.phonearena.com/phones/benchmarks 2 of the 3 best performing mobile devices out there are samsung phones. I'm not sure where you're coming up with your ideas, but performance wise, samsung is setting the curve, not behind it.

Count the number of phone with high performing statistics, now count the different company, I don't know where you live, but here in Belgium i can't count them on my hands.
Samsung has indeed the most preforming phones (if you look at the stats), but if i have a 300 dollar acer in one hand, and i have a 1000 dollar samsung phone in the other, you won't feel any difference, except the plastic, the size and quality of the screen, and of course the camera. Samsung's version of android is too inefficient, it wastes half of the phone potential. But you are right, they got most potential to be able to emulate a 3DS, but therefor, i hope the developers put another rom on it, AOSP is so much faster.
