So, this was a small tool I created for creating soundmods in the arcade version of JJBA: HFTF. This should work on other CPS3 games, however. This program allows you to find a chunk of data in the ROM's audio, and patch it out with new sound files you can import. You can also exports sets of sound replacements as zip files. Supported formats are MP3, WAV, and AIFF.
Here's a picture of the program in action:
