Hey Guys,

right now, I'm working on a replacement for the Nintendo Miiverse Applet.
Replacing the Icon and the Banner was the first part I worked on.
You can see some example pictures here:

I've worked on a private Homebrewtool which I want to start with this Applet.
It's a combination of some different functions.

I've tried one thing to replace the Applet.
1. I've created a CIA of my Homebrew which I can perfectly boot from Home Menu itself (like a game).
2. I've extracted the CIA, modified the DecryptedExHeader.bin and the NCCH.header and rebuilt the CIA.
3. I've encrypted the CIA with Decrypt9/GodMode9 and installed it to the NAND.
4. The Application doesn't show in the Home Menu. When I try to boot the App through the Applet Icon...:
- 4b. When I delete the Miiverse Applet (00 00 04 00 30 00 00 BE 02) it crashes instantly with the black "An exception occured" Window (because theres no app).
- 4c. When I install my Homebrew over the Miiverse Title ID, it shows "Miiverse" (it's normal) and gets stuck there (should load the homebrew shortly after).

Here are the changes I did on the CIA to install it on NAND (Left original / Right edited for NAND):

My goal is it to replace the Miiverse Applet with something else, unfortunately I'm stuck with loading a different App besides of Miiverse.
Is there a way to change the Title ID the Applet loads when clicking on the Icon?

Would be awesome if someone could help me out with the research.

OK, so where is the applet data located. I know where the actual Miiverse files are (the .tmd, .app, etc.) But where is the Miiverse Icon located?

OK, just thinking that if people want to help with this, they also would want to change the Icon.
probably.
When we've found out how to replace the Applet with another App (by changing the Title ID for example? not sure), I'll write a All-In-One Tutorial.

But first I need some help with this.

I'm in no place to sift through it right now, but I'd recommend searching through various files in the homemenu to see if the miiverse TID pops up and try changing that to another TID.

Out of curiosity, your app is launching correctly from NAND right? If you launch it from FBI it doesn't crash?

Okay, have to modify my Application and need to try it again.
I installed my App on NAND as "000400300000BE02" (Miiverse (olv) EUR) and it crashes when I boot it via FBI.
Installed on SD it works without problems.

Getting Error:
An error occurred (ErrDisp)
Error type: generic
Process ID: 15
Process title ID: 0x0004003000009802

Address: 0x00207570
Error Code: 0xd9605c05

Fixed that.
I can boot my Homebrew (installed on NAND with Title ID: "000400300000BE02") from FBI without problem but when I try to boot it from Miiverse Icon, it will stuck at the Miiverse Intro Screen (haven't changed this screen yet)

We need to fix that, but I haven't found out how, yet...
Please help with that
