Primary Volume Descriptor (PVD) Dumper in Python

[hiker13526]

I wrote a program to dump the Primary Volume Descriptor from a .bin file in IsoBuster format. Can be helpful to quickly dump the PVD to a file without needing to open IsoBuster, or used programmatically.

https://gist.github.com/anonymous/2a308 … 0b829a9c92

I have created a small batch file "PVD_Dumper.bat" which I drag and drop a .bin file to and it dumps the PVD to a text file in the same directory as the .bin file. This is the batch file:

Code: Select all

"%~dp0\PVD_Dumper.py" %1 > "%~dp1\%~n1_PVD.txt"

I attached both the batch file and python file to this post for easy download.

Requirements: Python 3.x

I know this is an old post, but wanted to say thanks.  I run Linux and can get the PVD from games with this hexdump command:

Code: Select all

hexdump -C -n 96 -s 33568 game.iso

But it doesn't output the results in exactly the same format as IsoBuster, and since the form validator seems to compare against that IsoBuster format I always have to massage the output a bit to get it accepted.  Just stumbled across this for the first time and tried it out and it works great.  Will save me a bit of time and effort for each disc I rip going forward.

Thanks!

Ha, man, that's some advanced formatting going on there.  Impressive.  I with a knew about that a while ago, would've probably saved a couple hours or so cumulative over all the discs I've dumped.  Very much appreciate you sharing!
