I am looking for a way/tool to extract the contents of an CVM (ROFS) file, which seems to be a container file used in some games (in my case: Kunoichi/Nightshade).
After searching the internet, I found that apparently some iso tools like UltraISO/Apache3/MagicISO are able to open an CVM file. But... no luck here. Any ideas?
I have this (futile?) idea of creating an "undub" (replace english voices with original japanese, but keep the english subtitels) for the game. Why? Because it's interesting from a technical standpoint and because I like the original voices better. The basic procedure should be simple: extract both versions of the game, replace the audio files (maybe demux/remux some videos), put it back together.
It's comparatively easy finding tools to convert given audio files. Opening CVMs should also be possible, as (for example) Persona 3 also uses them and someone created an undub for it.
This is your first stop but you need to register there first to see what this link is.
Xpert with the CVM plugin.
I get the an error: "invalid file header or file encrypted". I guess in this case I have an encrypted file, which means this is the end of the road for me. :(
Looks like I picked the wrong game for this. :)
