Trials in the Sky Chapter 2 & 3 .mcc file archives

Post by lionheartuk »

Hey Guys,

I've taken a look at the .mcc files from Trials in the Sky Chapter 2 and 3 MAP directory, its pretty clear they're archives, they appear to be lightly compressed too, but I'm pretty confident they contain 3D Models and texture files in there , much like the itp files in the later games from the series.(ao no kiseki/zero no kiseki)

The company uses Metaseqoia for all their 3D models and .tga files for their textures (according to the rest of the Kiseki series at least), so I'm certain there will be some .msq files in here somewhere (sure thats the right extension).

I've uploaded a link to a map from each of the 2 games here:
https://dl.dropboxusercontent.com/u/779 ... d3maps.rar

It'd be great if someone could take a look at this, I've not much experience so I can't say if it'd be complex to extract or not.

I also posted this on another forum, so if there is any news from there I will share it here too, so everyone knows all there is to know.

Code: Select all

# Trials in the Sky Chapter 2 & 3 .mcc and .itc
#
# Written by puggsoy
# script for QuickBMS http://quickbms.aluigi.org

get EXT extension

if EXT == "mcc"
   callfunction MCCEXTRACT
elif EXT == "itc"
   callfunction ITCEXTRACT
endif

startfunction MCCEXTRACT
   get FILES long
   goto 0x10
   
   for i = 0 < FILES
      getdstring NAME 0x10
      get OFFSET long
      get SIZE long
      get DUMMY long
      get DUMMY long
      
      log NAME OFFSET SIZE
   next i
endfunction

startfunction ITCEXTRACT
   idstring "V102"
   
   savepos POS
   get CHECK long
   
   for CHECK = CHECK != 0
      goto POS
      get OFFSET long
      get SIZE long
      
      log "" OFFSET SIZE
      
      savepos POS
      get CHECK long
   next i
endfunction


First of all, this works for both the .mcc archives, and also the .itc archives extracted from those. Secondly, the files that are extracted from the .itc archives seem to be compressed, but I don't know which compression type is used. All I can tell is that it begins with 0x000003EE, which is followed by the compressed size, and then the compressed data.

Oh awesome!

Though I am surprised to find a *lot* of .dat files in there.

I as expecting textures and models in clear recognizable formats.

For the next 2 games (ao no kiseki/zero no kiseki) there are itc files, and simply extracting those gives models and textures straight away in readable formats.

Perhaps they switched method between the games.

Edit, turns out they were always .it3, and comparing the 2 files side by side, they couldn't be more different.

Turns out I was wrong, these files do not contain what I expected (should have been obvious based on their sizes honestly, looks like I made a mistake and misread them.

Here are the files that I'm 100% sure contain either models or textures, they're still archives but thats it, they're in the map directory, filesize checks out too, so sure this is it.

If this isn't it, i guess I'll have to just go through the game on PC using NinjaRipper (doesn't work for Translated versions or Steam, but does work for Original Japanese releases).

Is nobody able to help with this at all?
Really would like to remake some of this in full HD.
