Not sure, but extracting/modding DS rom help.

So i've got this DS rom, that i'm trying to edit the script of Story Mode. I am able to extract all these files but i am unaware how to open them, those who are wondering they are .cnut files and the game is Smackdown vs Raw 2010. If anyone can help it would be nice

 

You could probably start here:
http://www.romhacking.net/

 

can't find anything about cnut files ther

 

It's a rom hacking community, you can look into their message boards.

 

Oh ok.

 

All the files contained in the filesystem are compressed in their own format, unless the formats are used in many other games, you most likely will not find any sort of documentation on them. They also aren't very clear on what is actually inside them because of their filenames except for a mainstream extension for audio formats being .sdat (sseq,ssar,swar,sbnk,strm etc.). Don't expect it to be easy.
