Is it possible to replace a sound sample in an SNES game by inserting a new one, such as replacing, say, the sound of Mario jumping with the sound of a duck quacking. Or perhaps more interestingly, replacing the instrument samples used in the music?
I realize that if such a thing is possible, there'd be a details to deal with, like sample quality, length, etcetra....and details on that kind of thing would be great, but I'm mainly just asking if it's possible at all.
(the only thing I can recall in my dim memory that would've indicated such a thing possible is the search for amateur talent for a Star Ocean dub, but for all I ever knew that was a cruel - if clever - prank)
