FINALLY. That Sunshell is a pain in the ass to install :/
BadgeData.dat is a file that's exactly 16 048 000 bytes long.
0x0 starts the two-dimensional array of entries 0x10 times 0x8A long.
Japanese file I got from
@Februarysn0w actually gives a bit more info on how the array looks like.
The first line is Japanese text, the second one is English, the third one is French, then German, Italian, Spanish, Simplified Chinese, Korean, Dutch, Portugese, Russian, Traditional Chinese and 4 lines that don't appear to be relevant, but they're usually the same as English ones.
Names of the badges appear at 0x35E80, again we've got a two-dimensional array 0x10 times 0x8A long, but this time it's one per badge, not one per series.
0x250F80 starts the section that looks like properties of the badges, although I can't find any values from Mng in there.
0x318F80 is another section with similar values, investigation will be held.
0xCDCF80 is yet another one and it appears a bit different, although complex as well.
I think one of them might be related to the image and another one might be banner for example. Will check later.
And that's all from this file, I'll try to edit the name of the collection to see if I was right on the first part, stay tuned
EDIT: Ooooops, sorry for double post, how do I merge posts over here...? :S
EDIT: It works! YEAH!
