Ok so first things first, I used the search here on Xbox-scene to try and find an answer...no luck.

I've got some sound files from 2 xbox games that I ftp'd onto my computer...
Is anyone able to help me out in finding an application that will open .TBX sound files
& also open
.SFX sound files and allow playback?

Or is there a way to convert these types of files to .wav or mp3 etc??

ANY info, ANY is helpful....EX= Links, whatever...
I'm really trying to tackle this

in the wiki for xbox media center, somewhere in those pages they have a list of programs that do this. There is like a list of 9 and they say which ones are good or bad. However, for me i was trying EA's NFS Carbon, which none of them work since they are in big .bins. For you though, they might.
