Primary Volume Descriptor (PVD) Dumper in Python

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!
