You can find more in-depth details in the comments inside the plugin and miniapp source files.
Miniapp payload: This asm payload based on luigialma's version from nitpic3d is responsable of terminating the rest of the problematic threads, reconstructing the partitioned otherapp from the recieved buffer, mapping it to 0x101000 with gspwn and finally launching it. We can't load otherapp directly from ROP because some gadgets and important functions are in the same area as the otherapp target address, so a small helper payload is needed first. ROP chain: From the rop chain and using yellows8's 3ds ropkit as a base, we can terminate some problematic threads and replace the area at 0x100000 with the next stage using gspwn. By overwriting a vtable, we can produce an arbitrary jump in the main thread and eventually jump to the ROP chain. Furthermore, the client sets up a buffer to recieve the data from the host, but it never checks the incoming data size, so we can produce a buffer overflow which overwrites important data after the recieve buffer. cia and is not signed, we can send anything arbitrary. Since this data is not part of the child. 
Vtable pwn exploit: The download play child application doesn't have the course files stored in its romfs, so it has to ask the host to send them when needed. This exploit consists of 3 stages + the otherapp. 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. After a while the exploit will trigger on the client 3ds(es). #Mario kart 7 rom eur driver#
Once the multiplayer menu loads on the host 3ds, select Grand Prix then 50cc then any driver combination and finally the Mushroom Cup. After that, let the client 3ds(es) join the group. On the host 3ds, select Local Multiplayer then Create Group. On the client 3ds(es), launch the download play application. (You will see a confirmation message in the top screen once the game launches). 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 can place your own otherapp at /kartdlphax_otherapp.bin, but keep in mind that the hax 2.0 otherapp doesn't work currently. 3gx file from the Releases page in the following directories depending on your game region:īy default, the plugin will use the built-in otherapp payload (universal-otherap).

Therefore, in order to use this exploit you need to install the 3GX Loader Luma3DS fork. The exploit uses a 3GX Plugin in the host system. 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. Kartdlphax is a semiprimary exploit for the download play mode of Mario Kart 7.
