So pardon me if I sound like a noob for asking this, but is it possible to get samples and instrument data from a Gameboy game and turn it into a sampleable (that's not a word is it-) sound file for a soundfont.

For reference, I really want a sample of the bass from Castlevania II: Belmont's Revenge https://youtu.be/XTPEYCw5uuM
