I'll look into it when I get a chance.
From what I can see, Shallie is the only game from the recent Dusk PC port that uses encrypted XML files, right?
Correct. E&L does not encrypt, and Ayesha does cursed things inside the executable instead.
Here are the seeds you are after:
{
"id": "A16",
"name": "Atelier Shallie",
"main": [
0x6df7,
0xc953,
0x72ef
],
"table": [
0xaa83,
0xac8b,
0x89cf
],
"length": [
0x1d,
0x13,
0x0b
],
"fence": 0x13fa
},
If you add the above to gust_enc.json
and use -A16
as parameter when calling gust_enc.exe
(e.g. gust_enc.exe -A16 GrowData.xml.e
), you'll be able to decode the encoded files.
I actually lost quite a bit of time looking for these seeds in the wrong place, because Shallie also encrypts the .pcsave
files from C:\Users\<user_name>\Documents\KoeiTecmo\Atelier Shallie DX\SAVEDATA\
with a similar, but not quite the same, algorithm and that one is listed first in the Shallie disassembly. So I found myself pointlessly trying to figure out why the seeds I found wouldn't work against the .xml.e
files, before realizing there was a whole bunch of different seeds in the function that followed.
Maybe if I ever find myself with nothing better to do, I'll add pcsave
decryption to gust_tools
, but I don't think that will happen anytime soon.
Oh, and of course, I'll produce a new release of gust_tools
with the updated seeds when I get a chance.
I can only get as far as finding the first literal value; I can't really follow the rest of the instructions as I don't know nearly enough about IDA.
