I think he means character slots.

If there is, I'd ask the guys who made Project Neos. They seem to be able to remove CSS slots, but I'm not sure if they can add it.
I actually talked to them about it. All they did was switch 4 of Marth's costumes to Lucina's costumes, but got rid of the changes between the two.

It would require converting the video into a moflex (a guide is around somewhere), and repacking the rom afaik.
It is not possible to replace it through SaltySD?

Actually they indeed added custom slots, for example, the orange yoshi, but it has some bugs

Sound effects, win themes, and sometimes background music mute themselves while I'm playing. Still not sure why.

This might be a little shameless from me to ask but I'm really running out of ideas now.

Long ago I used a pack some guy uploaded to /vg/, it was a rar with EVERYTHING ready to just download some nus3banks and build an update for the game.
It was when 1.1.4 was the current patch and it worked perfectly for me. It included a pre-decrypted patch and everything, it was really just get your music and go.
In time, 1.1.6 came out but the anon never reappeared with the promised updated pack and since I'm a lazy idiot, I can't decrypt files myself, let alone search for the current 1.1.6 to see if I can even extract its files.

So I started using Saltysd so my game could just read nus3banks directly from my SD. Everything was fine until I noticed smashcustommusic doesn't have the files for Midgar and Umbra Clock Tower.

How can I replace the themes of those stages?

And my shameless question: can someone prepare a similar pack like the one I mentioned?
I'm 99% sure you can't in this site because I think sharing an update would be illegal or something but I lose nothing with asking.

For Midgar and Umbra, use the Smash Wii U selections on smashcustommusic, then add "_3DS" to the end of the nus3bank's file name.

That was fast!
I'll try that and come back with results later.

It worked. Thanks!

But for some reason, the menu music doesn't work instantly.
It ALWAYS plays the Melee menu music and it resets to my custom one whenever I finish a fight and return to the Character select screen.

In the vault, the custom themes play fine.

Edit: I tried injecting my own music into the nus3banks and it still didn't work.

Edit 2: I ended up decrypting an update and modifyng the nus3banks myself.
Every theme works now but... is it normal the game still asks for an update in the home menu?
When I play it still says 1.1.6 so I'm going to asume the 3ds doesn't think my custom 1.1.6 is legit.
Some stages take a lot more to load tho but everything is playable.

May I ask if someone can make me A pack with the required files on it so that I only have too move the file to my sd card because my first attempt failed and I watched a video and did exactly what he told me I'll try looking at it again but I use cfw (luma3ds) on 11.2 O3dsxl and it's a freeshop version of sm4sh (usa) if the bin didn't work for usa version could it be I have (a). A pal version of sm4sh (B). A europ .bin file on usa version or (C). all things wrong ?

or will someone be able to Look at the folder and change it where needed and mail it to me ?

that would be nice

thanks in regrets, MilhousevanHouten

I noticed something that I think is weird since I'm not using SaltySD anymore.

In addition to the longer loading times per stage, I noticed there's a very slight pause when a character activates its Final Smash.
This may sound stupid but was it always like this in O3DS or it has something to do with my patch?
After adding all my music it ended up being a little over 700mb.
There were other issues but refer to my previous post for that.

THIS GUIDE IS OUTDATED, PLEASE GO HERE: https://gbatemp.net/threads/the-discussion-of-smash-4-modding-things.464298/#post-7171908
IF THIS WAS LINKED TO YOU BY A BOT, PLEASE LET THE OWNER KNOW THAT THERE IS A NEW LINK.
Extracting files for modding v2 (the rough draft) People please read through and make sure there is nothing odd. It does use godmode9 because I like to abuse features which are useful. This eliminates the issues of having half decrypted fileas as well (something that happened early on iirc).

What you need:
GodMode9: This is written for GodMode9, idk if it'll be the same for SafeMode9.
An SD Card with at least 2gb of space (I don't want to get a real number). If you are using a cartridge, you will need enough space to dump it as a cia (about 1.1gb more).
This pack once again: to extract files from dtls, same as in the OP.
A way to read files on your SD Card (I really hope that you have this because wireless will be a pain in the ass).
If you only have a cartridge copy of the game, you will need decrypt9 or hourglass9 (this is part of the holy guide).

Step 0: Dump your cartridge to a cia. (only do this if you do not have a digital copy of the game installed) (go to 2a)
In HG9, it is Gamecart Dumper > Dump to CIA.
In D9, it is Gamecart Dumper Options > Dump Cart to CIA.
Step 1: Setup GodMode9 as a payload by putting the GodMode9.bin in /luma/payloads and rename it to up_GodMode9.bin, down_GodMode9.bin left_GodMode9.bin or right_GodMode9.bin (whichever you prefer or isn't currently assigned), put your SD card back into your ds and hold that button on the d-pad on boot. You should now see a green bar at the top called [root] and some other information on controls.
Step 2: Go down to SYSNAND SD and go to Title > 00040000 > and the titleid low for your region
000EDF00 for US
000EE000 for Eur
000B8B00 for JP
Step 2a: (only for those who dumped their cart to cia) Go to SDCARD > files9 > ctr-p-acx(region letter) > CIA image options > Mount image to drive (skip to step 4)
Step 3: Go to content > 00000000.app and select NCCH image options... Mount image to drive. This should take you to a new screen that contains the exefs and romfs folder as well as other files.
Step 4: Select the romfs folder and press l on sound, dt, and ls. This will mark files for you to copy. (you do not need anything else as you aren't able to really edit them anyways)
Step 5: Hold R and press Right on the d-pad to go to a new pane and go to SDCARD > files9. Once you are there, hold R and press Y to make a new folder. You can go through the pain of renaming it, or give it a 1 to signify that it is the base files.
Step 6: Hold R and press L to get back to the first window. Press B until you get to the Title folder (the one with 00040000 and a couple other ones) and click 0004000e > titleidlow for your region (same as above).
Step 7: Select 00000017.app (may be different for other regions, just select the one that is larger than 5mb (hint: its like 300mb+)) and mount it again. Go to romfs and press l on dt ls and sound (if you want it). Hold R and press right to go to the window in files9 and make another directory by holding R and pressing Y. Name it something else (press right until you add a character works)
Step 8: Shutdown by pressing power or whatever it says on the top, and put your sd card in your PC. Put the base game dtls (the first one) inside /smash 3ds pack (the thing you downloaded earlier with the tools)/Obtaining Files/DTLS and put the update dtls inside /smash 3ds pack/DTLS Update/
Step 9: Shift + right click in the DTLS folder, click open command window here, and type "dtls dt ls" this should extract every file into an outdir folder. Once that is done, move it where you wish.
Step 10: Shift + right click in the DTLS Update folder, click open command window here, and type "python dtls.py dt ls outdir" this should extract every update file into outdir (note: there is no indication of this happening besides spam refreshing the outdir folder or watching the task manager).
Step 11: move the outdir folders to somewhere nice, merge if you want to (i personally am against this because old files have some use, but you likely won't need to be concerned).

So, small problem. I used to do Sm4sh mods on 3ds, and I really wanted to test a texture. However, Ohana3DS (original/not rebirth) no longer works on my computer. It crashes whenever it tries to insert data... Has anyone else had this issue?

Did you try loading the hand.bch model? I think it was one of those models or something that you needed to load first for Ohana 3DS to actually work with smash. If you can't find the .bch file, Here's one:
