Portraits position in main menu

This is not related to the position but how the tiles are displayed. If you take the 5x5 portrait and number every tile from 0x00 to 0x18 in the ROM you get 25. Imagine now them lined up in order. The tiles will be displayed as follow, and this will give the good displaying result:

00 01 02 03 08
10 11 12 13 09
04 05 06 07 0A
14 15 16 17 0B
0D 0E 0F 18 0C

I will have to modify the portrait displaying function(s) in my hack as I want to have 6x5, 7x5 or maybe 7x6 portrait so I don't know yet how hard it's going to be to modify the display routine, considering this pattern. The portrait following the first one follow the same pattern:

19 1A 1B 1C 21
29 2A 2B 2C 22
1D 1E 1F 20 23
2D 2E 2F 30 24
26 27 28 31 25

I checked FF3SE source code to check how Terri Sheshi was loading/saving the portrait and it was after confirmed in YY-CHR. In the 2011 version (japanese only), you can do a custom displaying format in a 00 to FF grid and save that format and the portrait are displayed completely instead of separated portions.
