Virtua Fighter 5 FS modding

Hello everyone. I'm a newcomer when it comes to Virtua Fighter. I'm been playing Virtua Fighter 5 Final Showdown and watching videos of various Virtua Fighter games. Particularly VF4 and 5. These past few days, I been modding VF5 FS and swapping songs from the game to songs that I enjoy and fit quite well with the game's atmosphere like Tekken since I'm a huge Tekken fan . Now I'm focusing on changing various sound effects in the game like UI sounds, punch and kick sounds, etc. But unfortunately, I hit a roadblock when it comes to unpacking the .csb files. So, I was wondering, does anyone have knowledge of unpacking these .csb files? I tried numerous tools to unpack them, but to no avail.

 

Neithermind everyone. I figured out the problem. The .csb files were compressed. So I had to decompress the .csb files first and then have the ability to edit them. I will be releasing my edits on them in a week or 2 weeks if anyone is interested.
