Dans les réponses, un type (disant avoir travaillé à l'époque sur des bandes sons NES) dit que dans ce cas précis, que c'est juste une coïncidence :
D'ailleurs, c'est même pas les mêmes notesThis is interesting but it is just a coincidence. Music and SFX are handled differently on the NES. also the full flag raising fanfare uses all 3 tonal channels of the NES. When picking up the mushroom in-game, one one channel is used for the effect. Maybe two channels for the mushroom pick up, regardless. The baseline in the overworld theme persists. Bassline* . I'm sorry to shit on this , but this just isn't how NES audio works. You'll CAN however find more stuff like this in SNES world with faster and slower playback of samples.
