GT2VolTools is a collection of two apps that will extract all files from and create new GT2.VOL files for the various Gran Turismo 2 game discs and demos (GTVolTool) and extract various bits of data from the game for easier human consumption (GT2DataExploder).
Unlike the original GT2Vol.exe program, these tools are both open source and supports the VOL files from the various demos. GTVolTool will also now explode the much simpler Gran Turismo 2000 VOLs (tested on PAPX-90203), and the various demos and final versions of Gran Turismo 3 and Gran Turismo Concept. However none of these new formats can be rebuilt yet.
GT2DataExploder only supports retail Gran Turismo 2 versions because the data format in the demo versions is a bit different. That doesn't matter though, since this tool is not generally useful. Most of the information it outputs is available in human readable form on my GT2 site
Download the zip below and extract the files. Then just click on GTVolToolGUI and you're good to go. If you prefer the command line instead, GTVolTool is the command line version of the GUI. Both do the same thing, but the command line program can output a list of file sizes/locations in the VOL, to make single file replacement easier. Command line usage is as follows:
Gran Turismo 2/2K/3 VOL File Exploder/Rebuilder - http;//www.airesoft.co.uk Usage: GTVolTool.exe -e2(xplode GT2) C:\\Path\\To\\GT2.Vol OutputDir <-u> OR GTVolTool.exe -r2(ebuild GT2) C:\\Path\\To\\explodedVol NewVolFile <-r> O R GTVolTool.exe -e3(xplode GT3) C:\\Path\\To\\GT3.vol OutputDir <-u> OR GTVolTool.exe -l3(list GT3) C:\\Path\\To\\GT3.Vol OR GTVolTool.exe -e2k(xplode GT2000) C:\\Path\\To\\GT2K.Vol OutputDir For -e2 and -e3 The last argument is optional and can be anything. If specified, any gzip archives (those files ending in .gz) will be decompressed into a 'decomp' folder within the folder where the .gz file is. For -r2 The last argument is optional and can be anything. If specified, files in any 'decomp' child directories will be compressed and have .gz added to their filename before being inserted -e2k This explodes a GT2000 VOL. Only tested on PAPX-90203. It does not support GT3. -l3 This outputs a list of the entries in a GT3.vol and their filesize/offset. This is primarily useful if you just want to replace one file without going through the entire explode - replace - rebuild process
GT2DataExploder on the other hand is command line only. It's usage is as follows:
Usage: GT2DataExploder C:\Path\To\Extracted\Vol.Files OutputDir Label Extracts data from various decompressed Gran Turismo 2 files into tabbed text files suitable for importing into a database etc. If present in the vol, it will parse ENG, USA, and JP data. Other European language data isn't used. Note that this tool WILL NOT WORK ON DEMO versions, the file data is formatted differently. Example: GT2DataExploder C:\GT2\PalVol C:\GT2\PalVolData PalVol
The download contains the source and binary of both tools. GT2VolTool(Gui) require the .Net Framework 2.0 to run. If you have an anyway decent/recent computer, you probably have it. Windows 7 and 8 include it automatically. If it doesn't run, that'll be what you need. GT2DataExploder requires the VC2005 Redistributable, again, unless you're on XP you should have this installed by default. You'll need 7-zip to extract the archive.
