Hi, I'm trying to extract the files from Exist Archive [Vita] package files, I got into the cpk and found the files I was looking for, but they're packed further.
The one I'm trying to open right now is a .tpk file with .ISF as the file header, if someone could help me with a bms file to unpack it that'd be much appreciated.

Code:

# Exist Archive: The Other Side of the Sky *.TPK
# script for QuickBMS http://quickbms.aluigi.org

idstring "\x0ISF"
get UNKNOWN long
get NUM_FILES long
get UNKNOWN long

savepos TABLE_POS

for i = 1 to NUM_FILES
   goto TABLE_POS
   get NAME_OFFSET long
   get FILE_OFFSET long
   get UNKNOWN long
   get FILE_SIZE long
   get UNKNOWN long
   get UNKNOWN long
   get UNKNOWN long
   get UNKNOWN long
   
   savepos TABLE_POS
   
   goto NAME_OFFSET
   get FILE_NAME string
   
   log FILE_NAME FILE_OFFSET FILE_SIZE
next i

AIF files, extractings from archive, this is a Morton swizzled DXT images, chunked by MipMaps. Format needs further research.

Yup, I knew they were AIF from reading the hex data. Thanks for the BMS script!

I'm working on it, all anyone seems to know right now is to rip the data with a hex texture extractor tool. There are a few AIF files that people know how to view, from SOA and TOC. Those methods don't work for these tho, I tested it.
