Well thank you for the thoughtful reply. Yes, that sounds like you know your way around digging through an iso file like this.
But no, I haven't even looked at the respective Isos for FFT and WotL to see what's in them, much less know where the files are stored. Knowing SE/Sony, they are probably compressed using a proprietary compression algorithm of some sort, which, when you run into that, you basically either need the exact software tool that was used to compress them, and decompress them with it, or you are "S.O.L," until someone comes along and cracks the algorithm.
However, yes, if we had both sets of files up in front of us, it should simply be a matter of converting the files that are in the PSX version to a format the PSP hardware is going to recognize as "a sound effect." That much seems simple enough, but you'd probably also have to plug them in with identical filesizes, since a program like this will run a check on any files it loads up into the ram, to make sure they are the right size, before putting its "green stamp of approval" on them and allowing the files to be displayed/played back/otherwise actually rendered by the program.
But like I said, I would have no idea where to begin. I know a bit about how games work, but as far as cutting them open and toying around with them, I'm afraid I'm still kind of an amateur.
Almost all the modding work I've done has been through preprogrammed utilities with a GUI. I've done some light hex editing, but that's the limit of my expertise.
You might say that I am "aware of" a lot more stuff than I'd claim to be adept at.
