Just checked with my own copy of the game - the sample data is indeed stored externally in a seperate folder
It's odd though since the external samples don't seem to be the original samples that were used, a good majority of them have different filenames and a good amount of them are MP3s
(weird stuff, I doubt MP3s are a good format for music samples ...)
Anyway you would have some luck opening the files (with the fixed headers of course) and replacing each sample with their equivalent in the 'Samples' folder
Keep in mind that some samples also have their tuning wrong so you might have to correct those, best of luck on whatever you're trying to do !
(Sorry for the necro, but I think this is worth replying with, feel free to scold me if you think otherwise
