Hello there! So you want to hack Mario Kart 7, huh? Well, you came to the right place.

Since ROM Hacking on the latest firmware is now possible thanks to HANS, I decided to make a tutorial to cover it because, well, no one else has, really.

So first and foremost, you're gonna need the following things in order to hack MK7:

* A way of accessing the Homebrew Launcher.

* A Mario Kart 7 RomFS (you can see a tutorial about it here).

* RomFS Builder.

* A hex editor (I recommend HxD).

All right, now that we have everything, let's start.

Building the RomFS

Okay, once you extract the RomFS, you just have to replace the files with whatever you want. Generally, people want to replace the tracks, so just go to romfs > Course and replace them freely. Of course, they have to match the name, so be wary with this.

After it's done, open RomFS Builder and locate the romfs folder with Mario Kart 7 on it, then click Go. Wait until it asks you to locate the file, which should be in the following location:

[SD Card]: > hans (NOT on the 3ds folder).

Once that's set, here comes the following part:

Removing the Hex Bytes

NOTE: Because the newest version of HANS no longer requires you to strip some bytes from the RomFS, this part of the tutorial is no longer neccesary, at least for the people who use the latest version of HANS (why wouldn't you, anyway?).

Okay, now you have to open the file in a hex editor and do the following:

You have to remove bytes from offset column 00000000...

To column 00000FF0...

So it should look like this:

After that's done, just save it.


Now for the final part...

Loading the RomFS

First off, you'll need to rename the RomFS file. Just having it named "aaasjhfdfsdashlolimsoedgy.romfs" isn't enough for HANS, because it needs to know the title of the game it's going to load the RomFS from. Yeah.

You'll want to go to the HANS menu with Mario Kart 7 loaded, so you can know the ID of the title, which should be here:



Only the last 8 digits will be neccesary. So, in my case, the ID and name of the RomFS I have to use is '00030800.romfs'.

Now that that's done, just extract the SD card, start the Homebrew Launcher, HANS, select YES on the SD card option thing and press start. Mario Kart 7 will start and your "hax" will load. Congratulations! You just learned how to insert MK7 hacks (this, in theory, should work with other games, of course).

Don't be shy of making any questions, because that's kinda the point of this thread. If you got anything wrong, just tell me and we can go through it.
...Unless, "of course", you start doing it intentionally, because, oh boy, I'll start shooting arrows at you.

Also feel free to point out stuff I got wrong, or better ways to do it, or stuff like that.

End thread.

Not really, as your tutorial is for 4.X - 9.2 systems. This one is for all system versions.

It's erroring every time right after MK7 boots. :L or it'll just show a black screen

also it's saying the path for the romfs is invalid even though it's the exact right filename

Hm, I feel like I wrote something confusing at some part.

Can you show me the name of your RomFS and the region of your MK7 game?

Sorry for my late answer! I found the solution:
I used IRONHAX to start the Homebrew Channel, and HANS ever crashed. Now I tried it with Homemenuhax and it works without any problems!!! ( except blargSNES, which crashes now when starting )
