HOW TO MAKE A NUS3BANK FROM A BRSTM (THE MANUAL WAY)

HOW TO MAKE A NUS3BANK FROM A BRSTM (THE MANUAL WAY)

Do you want to get your hands dirty? Are you man enough not to use the GUI that does everything for you? (Here it is if you're not man enough, what a loser: https://gbatemp.net/threads/easy-nus3bank-editor-with-gui.426370/) Do you just like doing things yourself?
Whatever the reason is, here's the tutorial for you.
But it's for Windows. I dunno what to do for you Mac/Linux peeps.

PREREQUISITES:
- This thing. You need it for the, uh, everything. Duh.

Use WinRAR or 7-zip or whatever to do the unzippity bop doo dah.
- A BRSTM
'Cause why else are you here?
- A nus3bank
We need one to inject the .idsp into one. Just take some random one from your Sm4sh dump or elsewhere.

INSTRUCTIONS:
1. Extract the .rar if you haven't already.
2. Paste your brstm into the "Smash IDSP Build" folder.
3. Drag and drop your brstm onto the sm4shidspbuild.bat.
4. CMD should pop up (a black window with white text) with a whole load of text! This is an example of what it'd look like. http://i.imgur.com/BOKECq6.png?1. (Wait a little bit, not everything's going to show up immediately.)
Also, in the Smash IDSP Build folder you should see a bunch of funky stuff happening. After it's done you should be left with an .idsp with the same name as your brstm.
5. Take the idsp and put it in the "injection & extraction" folder.
6. Take the nus3bank I mentioned in the last section and rename it to the same name as your idsp (I recommend renaming it as if it were a Sm4sh song, so snd_bgm_blahblahblah.nus3bank)
7. Hold shift and right click. You should see a button that says "Open command window here". Click it.
8. Like the idsp, a cmd window should appear. Type in "nus3inject.py *.nus3bank *.idsp 0"
9. It should look something like this. http://i.imgur.com/lsMhG8s.png
If it is, then you got it! There's your nus3bank! Go ahead and test it in game.
