Oh, hello.

So you may or may not have seen my previous tutorial on how to insert Mario Kart 7 hacks using HANS and wondered, "how the heck am I going to extract a RomFS/get it?!" well, that's precisely why I made this tutorial.

A RomFS has all the content of a game, but in an compressed (?) form, so we have to extract it if we want to hack a game.

As of now, there are MANY ways to extract a RomFS, so I'll pick one out of a hat, and for this tutorial, we'll be using HANSHelper.

So here's what you'll need:

* A game/title you want to dump.

* A way of accessing the Homebrew Launcher.

* HANSHelper.

* braindump prerelease.

Alright, let's start.

Dumping the game

So first, download braindump from the site and put it on the following location:

[SD Card]: > 3ds > braindump (don't create the folder if you're extracting it, well, the folder, I mean).

After that, extract the SD card and start the Homebrew Launcher. Start braindump, select the title you want to dump and braindump will automatically begin the process. Do note that it might be slow, depending on how big the title is. Please bear with this, at least for the moment.

After that's done, you should find the game on the root of the SD card on a folder called something like this:

0004000000xxxxx (the 'x'ses can be anything).

Now we go to the next part:

Extracting the RomFS

First, we put HANSHelper in the folder where the RomFS and ExFS are, then we boot it.
From there, HANSHelper guides us on the process, but eh, I'm still gonna list it here, just because.

We want to extract the RomFS, so we press 1.

Then it asks us what do we want to extract, so press r for the RomFS, as I doubt we're gonna need the ExFS (for now...).

Then it asks us to enter the path of where the RomFS is located, but since HANSHelper is already there, we're gonna press enter.

Now it asks us to enter the path of where do we want to save the extracted RomFS, so just enter where do you want it to go (I actually haven't tested this function yet, so I'd like it if someone told me if the way they did it worked...).

After that, it returns to what it was initially, meaning that the RomFS was already extracted.

Hooray! You just extracted a RomFS! Now it should appear in a folder explicitly called "romfs" in wherever you saved it.
Now you're free to go wild with it.

Again, ask me any questions you have as I'll be glad to help you (I barely get any replies...), and also tell me if I got anything wrong, or better ways to do it, or so.

End thread.

Placeholder for uh, things to come (that is, if there are things to come...?).

Well, the tutorial starts out a bit too fast for me. Like, how am I even supposed to be able to run Homebrew on a 3DS? I know there's probably dozens of tutorials out there, but i'd like to know of the most efficient, up to date method. Also, does my 3DS need to be a certain firmware? In that case, i'm probably screwed. :(

I had thought of also making a tutorial on that, but considering that it should be the simplest of things, and more importantly, that there are little to no free entrypoints, well, I'd rather not.

As of now, if you want to install the Homebrew Launcher, you need to have either of the following things (that is, you don't need to have ALL of these things):

All firmware versions

* Cubic Ninja.

* The Legend of Zelda: Ocarina of Time 3D and a Save Dongle.

* Super Smash Bros. for Nintendo 3DS, a New Nintendo 3DS and Linux.

9.X-10.1?

* Just your web browser and an extreme avoidance to wireless communications (so the web browser doesn't get updated).

If you don't have/can't do any of these things, you can't, sadly, launch homebrew for the moment.

MK7tester, that doesn't look like the MK7 ROMFS at all, are you sure it's not a different game?

I'm positive it's MK7, after all, it IS the game that's in the game slot when a run braindump.

Even tried it a second time, I got more files, but still no course...

That definitely isn't Mario Kart 7's romfs. You most likely selected the wrong target when you launched braindump. Mario Kart 7's romfs should look like this:

When you launch braindump, make sure that Mario Kart 7 is selected here:

Turns out my 3DS wasn't reading the MK7 game card correctly in braindump. Thanks for the help Yawshi!
