Idolm@ster (Xbox 360) HELP

ayylmao · **Posted:** Thu Aug 06, 2015 5:52 am

I'd like to work on translating the Xbox version of Idolm@ster using the preexisting translations from the PSP port of the game. I was already able to do so with a hex editor for one of the files, but considering the total amount of files I would have to edit manually, accomplishing a full translation would require an unrealistically monumental amount of work since I don't have the knowledge to write an actual script editor. So could someone help me by making one?

Example files.
The files provided are actually packs that contain both the script and the voice files associated with it (the .scb is the script, the .ahx are the voices files). The file which I translated is included for reference. A quick bms script to unpack them was already written 5 years ago, although there isn't any repacker. This may not be necessary though as it's just a matter of rewriting the sizes/offsets at the top of the .bna file after editing the .scb script (the .scb is always the first file in the pack for these regular game scripts). Editing the .scb file itself is pretty straightforward (it's basically just editing the UTF-16BE encoded null-separated strings, fixing the pointer/sizes located just above for the edited strings, and then fixing the pointers/sizes in the .scb header). I could go into more detail if it's needed.

Thank you!

Do you have an email I could contact you at? I'd like to help you with the translation.

For the sake of transparency, here's a reconverter I wrote for the dds script found here. I still need help with a script editor though.

Code:

Python scripts. I guess a tl tool is just a luxury now.
Build MSG from a null-delimited, UTF-8 text file:

Code:

import sys
import string
import struct
import os
import codecs
import re

fileT = open(sys.argv[1], "r+b")
fileTString = str(fileT.read())
name = str(os.path.splitext(os.path.basename(fileT.name))[0])
extension = '.msg'
msgName = "".join((name, extension))
print(msgName)
msgFile = open(msgName, "w+b")
msgFile.write("\x4d\x53\x47\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x45\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x3A\x00\x00\x00\x00\x0A\xEC\x00\x10\x01\xE0\x00\x00\x00\x00")
utf16Text = fileTString.decode('utf-8-sig').encode('utf-16be')
sizeText = str(struct.pack('>L', len(utf16Text)))
msgFile.seek(36, 0)
msgFile.write(sizeText)
msgFile.seek(0, 2)
print(msgFile.tell())
textPointer = int(0)
lineAmount = int(0)
print(textPointer)
textSize = int(len(utf16Text))
print(textSize)
for line in re.split('\0', utf16Text.decode('utf-16be')):
   line = line.encode('utf-16be')
   withNulls = int(len(line)) + 2
   msgFile.write(str(struct.pack('>L', withNulls)))
   msgFile.write(str(struct.pack('>L', textPointer)))
   textPointer += withNulls
   lineAmount += 1
   textSize -= withNulls
   if textSize <= int(0):
      break
msgFile.seek(32, 0)
msgFile.write(str(struct.pack('>H', lineAmount)))
lineAmount *= int(8)
checkFiller = int(lineAmount)
checkFiller %= int(16)
msgFile.seek(0, 2)
if checkFiller != int(0):
   msgFile.write("\xCD\xCD\xCD\xCD\xCD\xCD\xCD\xCD")
   lineAmount += int(8)
lineAmount += int(16)
totalSize = int(lineAmount)
totalSize += int(len(utf16Text))
msgFile.seek(42, 0)
msgFile.write(str(struct.pack('>H', lineAmount)))
msgFile.seek(16, 0)
msgFile.write(str(struct.pack('>L', totalSize)))
totalSize += int(32)
msgFile.seek(0, 2)
msgFile.write(utf16Text)

Insert MSG into .SCB:

Code:

import sys
import string
import struct
import os

fileD = open(sys.argv[1], "r+b")
fileP = open(sys.argv[2], "r+b")
filePString = str(fileP.read())
fileDString = str(fileD.read())
fileP.seek(0, 2)
endP = str(struct.pack('>L', int(fileP.tell())))
fileP.write(fileDString)
fileP.seek(148,0)
totalSize = int(len(fileDString))
fileP.write(str(struct.pack('>L', totalSize)))
fileP.write(endP)

Add file to .BNA:

Code:

import sys
import string
import struct
import os

fileT = open(sys.argv[1], "r+b")
fileP = open(sys.argv[2], "r+b")
filePString = str(fileP.read())
fileTString = str(fileT.read())
name = str(os.path.basename(fileT.name))
size = str(struct.pack('>L', len(fileTString)))
packedOffset = str(struct.pack('>L', int(filePString.find(name))))
offsetOffset = filePString.find(packedOffset)
fileP.seek(0, 2)
endP = str(struct.pack('>L', int(fileP.tell())))
fileP.write(fileTString)
fileP.seek(offsetOffset)
fileP.seek(4, 1)
fileP.write(endP)
fileP.write(size)
fileT.close()
fileP.close()
