Okay,First you have to start this code in file .bat
ctrtool --listromfs romfs1.bin >romfs.txt
In romfs.txt have all files we need and these are orderly.
Well,i'll start at bottom files in romfs.txt.You can see these files #####.If we can rename these files name correctly So we can repack successfuly.
use your hex to open romfs.bin and search "window_only.ctpk.lz" like this pic:
Next file is the files we have to rename
with binary code: DC 30 BF 30 F3 30 68 88 3A 79
look at 2 bytes first: DC 30.It's 30 DC exactly.go to http://www.rikai.com/library/kanjitables/kanji_codes.unicode.shtml
and it's ボ.and DC 30 BF 30 F3 30 68 88 3A 79 is ボタン表示("button display" google translated)
it's about ~4000 files like that.If you have much freetime you can do it completely about one week
