ROFS Compression\?Encryption? Method
Posted: Mon Sep 10, 2007 12:03 pm
I learned this today while doing some research on the type of compression\encryption method used on the CVM file I was trying to decode.
If you open a CVM file(or possibly any archive file) in a hex program and see something along the lines of
ROFSROFSBLD Ver# Date
within the header, it was compiled using a tool called CRI ROFS from a japanese company called CRI MIDDLEWARE

To learn more about the how the format works go here.(Poorly Translated by Google)

And finally a list of games that will most likely have had this tool used on them.

Since as the site states the file system used is the ISO9660, maybe someone will be able to come up with a tool for extracting files
from these archives files that have used the ROFSBLD TOOL.
I hope this information proves to be useful and someone can put it to good use cause I sure could use tool for this
