kartdlphax - A Mario Kart 7 semi-primary exploit
​

kartdlphax is a semiprimary exploit for the download play mode of Mario Kart 7. It can be used to run an userland payload in an unmodified 3DS by having it connect through download play to another 3DS with Custom Firmware running the exploit.

​

Installation
The exploit uses a 3GX Plugin in the host system. Therefore, in order to use this exploit you need to install the 3GX Loader Luma3DS fork.

In the host console, place the .3gx file from the Releases page in the following directories depending on your game region:

• EUR: luma/plugins/0004000000030700
• JAP: luma/plugins/0004000000030600
• USA: luma/plugins/0004000000030800

By default, the plugin will use the built-in otherapp payload (universal-otherap). You can place your own otherapp at /kartdlphax_otherapp.bin, but keep in mind that the hax 2.0 otherapp doesn't work currently.

Usage

1. On the host 3ds, make sure the plugin loader is enabled from the Rosalina menu (L+Down+Select), then launch the Mario Kart 7 game matching the region of the client 3ds(es). (You will see a confirmation message in the top screen once the game launches).
   
   
2. On the client 3ds(es), launch the download play application.
   
   
3. On the host 3ds, select Local Multiplayer then Create Group. After that, let the client 3ds(es) join the group.
   
   
4. Once the multiplayer menu loads on the host 3ds, select Grand Prix then 50cc then any driver combination and finally the Mushroom Cup. After a while the exploit will trigger on the client 3ds(es).

Keep in mind that while you can send the exploit to 8 consoles at the same time, the success rate seems to decrease for each console added.

Hey does this mean there would be a way to play custom ctgp-7 maps with unmodded users?

Theorically: yes. Practically: very unstable and hard to maintain, better to use the standard way of installing CFW.

 

[SuperDan]

Smart Buggers !!

yoo...that is a sick way to lunch a payloader

wait.... does CTGP 7 local muti player even work?

I think it freezes if you are using an old 3ds with a physical cart to host, but other than that i think so yes.

This exploit aims to install CFW on a clean 3DS or just run homebrew on the sysFW and keep it uncharted aftwards?

but it would have to be muti cart yeah? I never got single cart to work with CTGP 7

Depends on the otherapp you use. By default it boots to B9S installer.

CTGP7 multicard works fine if all consoles are using the same settings. (Except for the bug where o3ds can't create rooms with cartridges)

This is awesome! I love exploits that don't require any files to be put on the candidate system, such as the Wii Mini BTHax exploit.

So a hacked 3DS can now hack 8 other 3DS systems at the same time without doing anything to their SD cards beforehand, just using Mario Kart 7 and Download Play

this is the funniest @*#$ing thing I love it so much :')

 

[MiiJack]

All that I'm hoping is for multi regional download play now.

it's pretty insane how this hack 'spreads" out multiple systems....wirelessly

 

[Gamemaster1379]

Honestly this kind of hack is a great interim step. I know a lot of other latest system versions basically rely on the seedminer(?) exploit which uses the online services which won't be there for forever. At least with this, you can exploit new units so long as you have already exploited ones.

All models should be supported by browserhax-XL.
