ROM Hack Streetpass Mii Plaza - Puzzle Editing [QUESTIONS]

[xXDungeon_CrawlerXx]

Hey Guys,

Since yesterday I try to replace Puzzles with my own.
I found the needed files for the Puzzles in RomFS of "Streetpass Miiplaza".
Location of the Models: "romfs\graphics\model"
Location of the Preview Images: "romfs\graphics\tex"
I edited some preview Images and some Models already, rebuilt the romfs and rebuilt the cia.
I've encrypted the CIA with Decrypt9UI and deinstalled the original one from EmuNAND.
After deinstalling the original, I've reinstalled my modified one.

Unfortunately nothing changed...
Even If I replace the Models with other original models, nothing changes.

After that, I deleted BossExtData and ExtData, still nothing changes.

I guess the models which Streetpass MiiPlaza uses is in BOSS.
For example the file "!!!$!!!!J!!+s(" contains all standard Puzzlenames (up to Final Fantasy Explorers) and a lot of CGFX-Files (80 CGFX Files).
The Filesize: ~22MB

I guess all Puzzle related Models and Textures are saved in this file.

Unfortunately I can't just modify the file because it has a checksum.
If I edit just the Puzzle-names, Streetpass Mii Plaza is unable to load the file and deletes it completely.

Could someone help me finding the checksum of this file + extract/insert CGFX-Files to it?

EDIT:
Uploaded the BossExtData file here:

Extracted one CGFX-File from it (Offset: 20028 - 2BDC8), decompressed it and got this:

Spoiler: IMAGE

I guess we could edit this stuff BUT there's the problem with reinserting files + the Checksum.

Would you help me with this?

Do I need to have a CFW for this too work? Or can this work in official firmware?

If you can use JKs savemanager from HB then your good.

I can use cia's as well. But the steps are like:

-Replace save file in SD card
-run JKs save manager
-profit?

DUDE, WRONG THREAD!
I know how to use the Save, I've installed it when the savefile was released!

In this thread I want some help with replacing original Puzzles with Custom ones!
