Custom mii icon save injection tutorial

Have: The inject pack, TexConv2 (can't link here, google) and https://github.com/aboood40091/GTX-Extractor/releases/download/v2.2.1/gtx_extract_v2.2.1.zip (warning: 40.2 MB download) and lastly the nvidia dds utilities - https://developer.nvidia.com/gameworksdownload#?dn=dds-utilities-8-31


--------------------------------First time setup---------------------------------------
-Extract the inject pack and GTX extractor to their own folders
-run dds utilities installer
-go to the install directory of dds utilities (C:/Program Files(x86)/NVIDIA Corp/DDS Utilities/ for me) and copy nvdxt.exe to a folder beside your inject pack and gtx extractor folders
---------------------------------------------------------------------------------------


-------------------------------Using CEMU for testing----------------------------------
-Download the latest version of CEMU and unzip into any folder
-Put your dump somewhere CEMU can access
-File -> Load, select your game.
-Now you are probably seeing a black screen that you are stuck on, what you need to do is remove all controllers then plug as many as you want back in. (Options -> Input Settings to drop/connect controllers)

*dump your game then continue here*
-to install a save you should just be replacing files in \cemu folder\mlc01\emulatorSave\ (or something similar) for me I had a folder called d72e798a_255 inside which is where I put the contents of my save's common folder and d72e798a for the 80000002 folder
you should now be good to test using that save
----------------------------------------------------------------------------------------

Step 1: dump you save with saviine https://gbatemp.net/threads/release-saviine-wiiu-savedata-tool.399833/

Step 2: make a complete backup of your save that you never touch - just in case

Step 3: go into the common folder of your game save and find the texture folder then copy any .TEX file into your inject pack folder

Step 4: extract the tex the same way you would a nut (in the newer versions drag and drop the .TEX on top of A.Extract.A.bat, this should print out some text that looks exactly like this:
	Slot 0 ID 0   1 Mipmaps     ABGR_8888/A8B8G8R8

It will then tell you that TexConv2 crashed, don't worry about that. That should happen.

Go into your Convert folder and you should have a 0.gtx, take that and move it over into your gtx extractor folder

Step 5: drag and drop 0.gtx on top of gtx_extract.exe and you should get 0.png

Step 6: edit 0.png to your hearts content then move it to the nvdxt.exe folder and run the command: (Note: to open command prompt from a folder hold shift and right click some blank space in the folder then select "open command window here")

	nvdxt.exe -file 0.png -nmips 1 -u8888

then you should get a file called 0.dds, take this and move it to your inject pack folder.

Step 7: From within the inject pack folder run the command:

	NUT_Inject.py mtex_00_00.tex 0.dds 0

replace "mtex_00_00.tx" with your .tex name

Step 8: Inject your save using saviine (Note: you shouldn't have to inject the whole save, just inject the relevant files)

Enjoy your custom mii icons!
