Burning Rangers: Hacking ISO to swap English music tracks with JP versions (ADX)?

Is it possible to do? I got into Burning Rangers because of Phantasy Star Online/Universe's BR levels, which always used the Japanese audio tracks. I want to swap the music from the Japanese iso to the English one without affecting the dialog. If it can be done, what would be the easiest way?

Edit: Just to reiterate, these are ADX audio, not CD tracks.

 

For anybody who runs across this thread on Google looking for the same thing, I did figure out how to burn a working Saturn hack. The problem was that I was googling things like "hacking Saturn ISOs" and "Saturn rom hacking". Once I did a search on how to AUTHOR Saturn ISOs, in regards to hacking, I found what I needed pretty quickly.

I got mkisofs from here: http://smithii.com/cdrtools

I used these instructions:

Except I used PowerISO, and I got my IP.BIN from here (since CDRWin won't see my drives): http://phemusat.tripod.com/ by downloading the "SMS emu version 2" file (it has the file inside the zip). I then grabbed the BGM file from the Japanese version and pasted it into the US one, and burned the ISO using the instructions above.

I noticed that the opening movie still had the crappy English song, so I found this program, which lets you listen to ADX files and cinepak movies. I got it from here:

This allowed me to isolate the OP.CAK file which (logically) was the opening, which I then swapped in and overwrote the original opening. So now I have a working image that plays the Japanese opening movie and music, and the English dialogue is untouched. The only problem is it seems that the order of the audio files isn't exactly the same, so I get a weird floty ballad on the Sonic Team logo. The program I used to preview the media files will let me extract them as waves. Does anybody know of a program I could use to pack them back up as an ADX if I were to unpack and reorder them all correctly using the English set as a guide?

I realize my original request might have been a tall order for the hacking advice, but I think I've demonstrated that I'm smart enough, and more than willing to help myself....but still I would appreciate a little guidance if anyone has any to offer.

 

Hi all!

In order to avoid having to update 2 threads, and risk getting yelled at for quadruple posting, I'm going to post the link to my (nearly identical) romhacking.net thread, for anyone who's interested or find this thread through Google:

http://www.romhacking.net/forum/index.php/topic,16806.msg247555.html#msg247555

If you do have questions or thoughts, feel free to reply, and I will post again if I'm ever successful. I just didn't want to give the impression that I'd given up (or died, lol). I found some neat tools that I link to in the thread above, as well.

Thanks!
