Lu-Scene-A

Lucina Alternate Costume Lu-Scene-A

This mod is based off of an alternate costume created by Cool Smash Alts~ @Smash_Alts

Bear with me on the tutorial as I can't explain everything when it comes to adding a character slot, since it's different for most people.

This mod was created on Smash Patch 1.1.6 and using Sm4shexplorer v0.07. This download includes 2 versions: One is replacing the 5th character slot for Lucina, and the other comes with all the images and model files to add a slot for Lucina. 

This download is unpacked, meaning you need Sm4shexplorer in order to install it. Sorry :(

Now I'm going to continue assuming you know how to use sm4shexplorer.
-To replace the 5th slot is simple: 
Open the Lu-Scene-A Replacement folder
Open the c04 folder and there are the files you have to use to replace into sm4shexplorer
Drag and replace the model.nut and model.nud files into the corresponding folder in sm4shexplorer, in this case is under data/fighter/lucina/model/body/c04

-To replace the portraits is the same thing, just different folders and location. 
Open Lu-Scene-A Replacement folder 
Open the chr folder, and there are the files you have to use to replace into sm4shexplorer
The portraits are located under data/ui/replace/chr

chr_00 is for Battle Portraits 
chr_11 is for the Results Screen Portrait
chr_13 is for the Character Select Portrait
And stock_90 is for the Stock Icons

Simply drag and drop all the included chr_stuff into their corresponding folders. With the way that they're order, you can select the folders, and drag them onto the chr folder in sm4shexplorer, and it will paste them into the correct folders. If for some reason it creates more folders in sm4explorer, delete those newly created folders, and just paste the files into their correct folders.

And that's it! That should replace the 5th character slot.

Now adding character slots is a bit more complicated and requires more reaserching for you do to. 
It requires hex editing the ui_characters bin file with a program called Parameters
Also (in some cases) editing the TexID on the model.nut and model.nud files
Renaming all the folders, and chr files 
Don't worry, the information is easy to find, and simple to do. 
If you really cannot get the files to work, message me and I will do my best to help you out. I work A LOT, and only have time in the dead of night to answer questions.

Just so you know, I mainly followed these videos by xXSonicBrawlerXx and StylesX2, links are broken on purpose since gamebanana likes to do weird stuff to links
