ROM Hack [Tutorial] Edit the HomeMenu

[Asia81]

TitleID Yes, product code no (except with 3DSBuilder, but 3DS Builder is not used here)

--------------------- MERGED ---------------------------

I can try something for the product code, I will check tonight, I'm not at home

 

[MasterLel]

Well I can't get the Japanese keyboard to work properly, so I'm thinking about using the japanese cia, change its product code and TitleID and install it over my european keyboard, which should fix the problem.

 

[Traiver]

Hm....

 

[Zan']

Does this mean we could change icons, bar positions, add buttons (e.g. "Load the HBL" button) and so on? Did anyone manage to do it?

Not sure what you mean by load the hbl button but you can change color and positions.
@MasterLel and @TheDeKay habe done it.
And I am pretty sure changing the Icons is possible as well.

But someone could possible rewrite everything in code etc and compile it. And the rebuild it with the Home Menu headers etc. I guess that would be "easier" but probably requires reversing as well.

Just take the Header Files from the european one. And everything else from JP.
And possibly overwrite the language file

 

[MasterLel]

Adding buttons should be possible but adding a function to it, like loading the hbl or whatever when you press it, is impossible. (well in theory it's possible but it would requires reverse engineering on the code.bin)

Just tale the Header Files from the european one.

Gonna try but I doubt it will work.

It should. The header includes ver etc.
And you effectively change code etc.

However the keyboard may even be bound to the JP region. That would require you to nop this requirement. And in that case title ID won't matter.

i dont know why but when i try to install my custom menu FBI says "error this title already exist" then i reboot my console and its bricked ._:

thanks ¬¬

Follow this :

Don't install a customized home menu over another customized one. You have to install a clean home menu to overwrite the customized, then you can install your custom cia.

like this : normal HM > custom HM v1 > normal HM > custom HM v1.5 > normal HM > ...and so on.

Use an updated FBI and don't encrypt cias downloaded from 3DNUS, they are already encrypted.
Also, if your console crash after the installation, it's normal, just reboot it.

he's right thought... You don't buy a car if you don't know how to drive it, and then ask the vendor "hey teach me how to drive pls"
And OP said :

Q: How to...
A: I don't know.

You can easily brick your system if you don't know what you're doing.
