I just figured out how to add portraits to the random select centerpiece!
And I figured out how to add more "stages" behind the character selection portrait!
AND I UPDATED ALL OF MY CHARACTER PORTRAITS! YOU HAVE TO REDOWNLOAD THE FILE IF YOU WANT UPDATES.

All are in the usual mediafire folder.
http://www.mediafire.com/?sharekey=3d487a4dc671b9cfb81a3d47453fcce4d5408aad5d4418417700cf6b59479179471ca34169c0e0200c2ee58f677a41b5
Now how the HELL do you add the damned prefil portraits to the SFF!?
It doesn't work when I do it!
To be specific, your Miyako prefils, I added them to the SFF.
And to her DEF file I added the path data/char/miyako.def for her arcade intro.
And it will not load the intro up, skipping to the vs screen.
In the profiles of char, the "DEF" is the only file that can not be shared without change because the amount of chars from the other one is different and may have a conflict of codes.
You see, by default, Kyo, Lyzer, and Haruhi are already occupying the image value of 0,1 and 2.
His "DEFS" should be created from just one editing the value of the PCX image and added the "char.sff.
Just wait a little while I'm finishing the rest of the tutorial in English the rest of the screenpack.
hope you don't mind if i help right hloader?
ok to add the profile pics you need to open fighter factory (or any sff editor)
open the char.sff in the char folder in data.
add your portraits as the following way as image 3 (unless you already have image 3 taken, use 4 and so on)
all images HAVE to be 320 x-axis and 0 y-axis
use group 2 to add the emblem
use group 4 to add the character pic (the diamond one)
use group 6 to add the character name (the one that has it on the left bottom corner)
use group 7 to add the small white emblem
and finally use group 8 for the character info
make sure that they have the same image number but are different from previous portraits that are already installed in the char.sff
save and now open any of the .def files in the same folder
(i use kyo.def since its easier to find the text you are going to edit)
copy everything in the def file into new .txt file.
now this is the tedious part (not really)
now find "2,0" using Find (Ctrl+F)
change all the zeros next the two into the number you used for the portraits

now save the txt as a def file in the same folder as kyo.def with the name of your choice (akuma, wolverine, etc.)
finally the last part!
Spoiler, click to toggle visibilty
now go to your chars file in your root mugen file and open the character that you want to designate your intro
(example ShinGouki) open your character's def file and at the bottom there is a line
;[Arcade]
;intro.storyboard = intro.def
;ending.storyboard = ending.def
now change that into this (example)
[Arcade]
intro.storyboard = data/char/ShinGouki.def
;ending.storyboard = ending.def
save and you are done!
now open your mugen and choose your character in arcade, and see if it worked!
if it didn't or if there is pink (this happens rarely) you must recheck the portraits and see if they are transparent
hope you find the tutorial helpful until HLoader releases his! 
Edit: Credit goes to DarkFoxX since i used his tutorial and made it 3 times longer to see the step by step procedure
EDIT: if you place your portraits as image 3 or 5 or whatever, use THAT number and don't use the 4, as it was used as an example!
