Tutorial  Updated

Using "smashhax" with Linux

If you can use the browser, I suggest that you use the new browserhax (up to 11.0.0-33!) in the meantime.

Try out Ubuntu 15.04: http://old-releases.ubuntu.com/releases/15.04/

This requires a New 3DS. The demo version doesn't work and is patched. If you have 1.1.3 or newer delete/disable the update data.

officially called smashbroshax sometimes smashax
Here is a new tool I call smashbroshax-helper. It is a graphical interface for the exploit which simplifies most of the process of broadcasting the packet. It requires almost no setup outside of creating a bootable Linux USB/DVD.

Important notes:
  • This does not work on Fedora or Red Hat-based distributions because aircrack-ng needs to be compiled on it (and I can't figure out how to install the needed things).
  • Don't use a virtual machine!
  • This probably will never work on Old 3DS.
Download smashbroshax-helper beta

It is recommended that you use a live Ubuntu 15.04 image. Versions 15.10+ have issues. http://old-releases.ubuntu.com/releases/15.04/
  1. Create a bootable USB/DVD with a Linux distribution (there are various guides online).
  2. If possible, get a second USB/SD card/storage device, download and save the above .zip to it.
    • Don't extract the contents of it to the USB device, as it might cause problems. Just save the .zip file to it.
    • If you can't do this, you'll have to connect to the Internet while in Linux to download it.
    • If using a bootable USB, make sure you can use two ports at a time. Don't take out the Linux USB while it is being used!
  3. Restart your computer and run the bootable USB/DVD you created.
  4. Extract the contents of the .zip to the Desktop.
  5. Open the smashbroshax-helper folder and double click "smashbroshax.sh".
  6. Follow the on-screen prompts.
  7. If everything goes well, you should now have homebrew!

If you would like the full tutorial, involving terminal usage and compiling:
To reverse the changes to your wireless interface and remove issues connecting to networks after, rebooting your system or changing it to "Managed" instead of "monitor" should fix it. How to do that is in the second to last section.



@Cydget made a script that condenses most of this into a script. I have not tried it myself yet but it seems to work for others.
So, I made a little script for this. If anybody wants it, then unzip this file and read the readme. And yes, I like to pipe things. http://www.mediafire.com/download/oulnubnzkk9g3i0/smashhaxEZ.zip

Requirements
  • Any Linux distribution should do (this has only been tested with Debian-based distributions). Windows and OS X users should wait or find a method for now, sorry!
    • Please do not use Linux in a virtual machine, it likely won't give direct access to your wireless card. Dual boot or use a live USB/disk.
    • The recommended distro to use is Ubuntu 15.04 (link to Ubuntu MATE 15.04).
  • A Wi-Fi-capable wireless card.
  • Super Smash Bros. for Nintendo 3DS Full or Demo.
  • New 3DS. This does not work on Old 3DS.
  • Patience. The hax is sort-of unreliable so your game will most likely crash a few times.
  • Recommended: Another device to access the internet (phone, tablet, computer, console).
Preparing
  • Install these packages using your package manager. For example, "apt-get" for Debian-based distributions (including Ubuntu).
    Code:
    openssl libssl-dev libnl-genl-3-200 libnl-genl-3-dev libnl-3-200 libnl-3-dev pkg-config
  • Find your wireless card's interface by opening a terminal and using the command "ip link". It would be something like wlan0 or wlp3s0.
    Code:
    ian@ian-VPCEG34FX:~/Desktop/aircrack-ng-1.2-rc2/src$ ip link
    1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default 
        link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    2: eth0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast state DOWN mode DEFAULT group default qlen 1000
        link/ether xx:xx:xx:xx:xx:xx brd ff:ff:ff:ff:ff:ff
    3: wlan0: <NO-CARRIER,BROADCAST,ALLMULTI,PROMISC,NOTRAILERS,UP,LOWER_UP> mtu 1500 qdisc mq state DORMANT mode DORMANT group default qlen 1000
        link/ieee802.11/radiotap xx:xx:xx:xx:xx:xx brd ff:ff:ff:ff:ff:ff
  • You probably already have it, but get the homebrew starter kit and place it on your SD card.
  • Download the smashhax .pcap files from the releases section of the smashbroshax repository.
  • Determine the .pcap file to use. This should be straightforward using the file names.
    The built beacon-hax pcaps are located under "pcap_out/". In the filenames, "vXYZ" means game-version "vX.Y.Z". Full-game filenames for USA include "gameusa", while the other regions filenames include "gameother".
  • Get the "Otherapp payload" from the Homebrew Launcher site and save it to "smashpayload.bin" at the root of your SD card.
  • Download and extract aircrack-ng's latest release source.
  • Save aireplay-ng.patch from the smashbroshax repository in the folder "aircrack-ng-1.2-rc2".
Compiling aircrack-ng/aireplay-ng
  • Open a terminal and go to the "aircrack-ng-1.2-rc2" folder.
  • Use the command "patch src/aireplay-ng.c < aireplay-ng.patch". If you get the following then it has succeeded.
    Code:
    patching file src/aireplay-ng.c
    Hunk #1 succeeded at 560 (offset 1 line).
    Hunk #2 succeeded at 573 (offset 1 line).
  • Run "make" and wait. The program should be compiled with the patch now. If you get the following as the last line then it has succeeded.
    Code:
    make[1]: Leaving directory '/path/to/aircrack-ng-1.2-rc2/src'
The moment of truth
  • Run these 3 terminal commands in order, using the wireless interface (from "ip link") you found earlier.
    sudo ifconfig wireless_interface down
    sudo iwconfig wireless_interface mode monitor
    sudo ifconfig wireless_interface up
    sudo iwconfig wireless_interface channel 6​
    (the last line was suggested by @difool. and might make the payload trigger faster)
  • Enter the "src" folder in your terminal.
  • Run the following command to start broadcasting the packet: "sudo ./aireplay-ng --interactive -r /path/to/smashbros_version_beaconhax.pcap -h 59:ee:3f:2a:37:e0 -x 10 wireless_interface"
    Use the .pcap file and wireless interface you found out earlier.
  • On the 3DS system, start the game, then choose Smash and Group. Wait for the magic to happen.
Encountering errors? Something confusing?
  • Does running aireplay-ng end with "End of file"? You might be running your installed version of aircrack-ng. Don't forget the ./ for "sudo ./aireplay-ng ..."!
  • Please tell me the distribution you are using and the error you've encountered. This will help me fix your issue faster.
  • If you don't get something, don't hesitate to point it out! I want to help anyone I can.
  • Did you spot an inaccuracy or mistake I made? It would be great if you can tell me that too.
  • This was before the Otherapp payload selector was added to the HBL site. This is kept here for legacy reasons or something.
    • Determine what file you need to get from the Homebrew Launcher Payload section:
      With the release builds, the hax loads the payload from SD "/smashpayload.bin". This should contain the hb-launcher(https://smealum.github.io/3ds/) otherapp payload. Until there's a proper otherapp payload selector on the hb-launcher site, the payload can be downloaded from the following URL(see also https://github.com/smealum/sploit_installer):
      FIRMVER values(without quotes):
      • "POST5" = non-New3DS
      • "N3DS" = New3DS
      REGION values(without quotes):
      • "U" = USA
      • "E" = EUR
      • "J" = JPN
      MENUVER values(without quotes):
      • "11272": Non-JPN, system-version v9.0.
      • "12288": System-version v9.2.
      • "13330": System-version v9.3.
      • "14336": System-version v9.4.
      • "15360": System-version v9.5.
      • "16404": System-version v9.6.
      • "17415": System-version v9.7.
      • "20480_usa": USA, system-versions v9.9-v10.0.
      • "19456": Non-USA, system-versions v9.8-v10.0.
      MSETVER values(without quotes):
      • "8203": System-versions below v9.6.
      • "9221": System-versions starting with v9.6.
      For example, the payload URL for New3DS USA 9.9.0-X - 10.0.0-X is:https://smealum.github.io/ninjhax2/Pvl9iD2Im5/otherapp/N3DS_U_20480_usa_9221.bin
      The end result is a file named "smashpayload.bin" at the root of your SD card.

When I was looking for usb wifi adapters, I was planning on buying that one until I found in aircrack forums and reddit, that the adapter doesn't support monitor mode and that's a problem getting the beaconhax on.
https://forum.aircrack-ng.org/index.php?topic=641.0
https://www.reddit.com/r/hacking/comments/2rzo86/aircrack_and_tplink_tlwn725n/

I don't know if that's true or not, but I started having doubts of buying that adapter, so I bought the TP-LINK TL-WN722N (which it worked), shown on this list: http://www.wirelesshack.org/top-wardriving-usb-adapters.html

I installed kali linux on live sd card and my internal wifi adpater send packets but my game doesnt do anything, i was forced to update to 10.3.0-28U in order to update smash to 1.1.2, i put the new otherapp payload. So basically im succesful at sending packets but my game doesnt act.

Edit: I also get that the mac address doesnt match the specified address and I am using the smashhaxEZ method, what should I do to get it to work? ( it sends packets anyways but doesnt load)
Edit: reached 9000+ (with 9-10pps) packets and still nothing.

Smashbroshax has not yet been updated for 10.3. Wait for Yellows8 to update it.

Please tell me what I'm doing wrong then because I followed the youtube video provided in the link along with a smashhaxEZ folder and I'm still getting ./aireplay-ng command not found. I've tried Ubuntu at first but got the same message so I've installed Kali Linux onto a live USB and actual hardrive and still keep getting that stupid message. My 3ds is on 10.2 right now and I'm not updating this time around at all. I also have a o3ds at 10.1.28 but the cart slot and trigger buttons wont work. Dunno what to do besides getting ahold of cubic ninja

So I'm curious, since people are claiming that the smash demo doesn't read from the sd card, meaning that you have to direct it to an online payload, does that mean that using the demo version to execute smashhax is a tethered entrypoint?

I already have access to the HBL loader through oot3dhax which I updated to 10.3 using SVDT, but I'd like to have a backup primary entry point just in case.

(I can't be assed to fucked up my smash save for it either.)

you have to build the .pcap files yourself with the PAYLOADURL option. apparently it's not very stable.

as for "fucking up your smash save", that's not going to happen.

I'm not concerned with compiling an airplay build from the source. So I'm reading the OP again, it looks like using the demo version or normal version is irrelevant. This isn't a very good entry point since you'd need to broadcast this every time time you wanted to gain entry. That is, unless I am reading it incorrectly.

you're right, it's not a good entry point. it's better for installing a more permanent one (for example, if you updated your system but forgot to update ironhax first).

Very True, This is definitely more of a PoC than anything else. Better an unstable entry point than no entrypoint I'd say.

well ever since I was told about the "channel 6" thing, it's been more reliable in activating for me.

I haven't tried building a custom .pcap for the demo, so I can't comment on how reliable it is.

People are likely having trouble with self compiling because they aren't considering hardware variation.

I have a new 3DS with 10.3.0-28U.
I have a US smash cart with 1.1.2 update installed.
My wireless card supports monitor mode
My wireless card is in monitor mode
My wireless card is set to channel 6
I followed the instructions with no errors, and ran:
sudo ./aireplay-ng --interactive -r smashbros_gameusav112_beaconhax.pcap -h 59:ee:3f:2a:37:e0 -x 10 wlan1
And the output looks the same as the videos online (shows that packets are being sent).
I open Smash, press Smash, press Group, and wait.
After a few minutes of nothing happening, I press back and press Group again, to try again. Nothing happens.

Any ideas?

Try using SmashhaxEZ from @Cydget rather than the actual command:

@ihaveamac Could you edit the tutorial and remove the part about the demo working if you compile it yourself. Even if you compile it yourself, it still doesnt work. It is cache related according to yellows8 and it looks like it will never be fixed, especially with the new update to the demo completely blocking all hope for it to work in the future.
