So a lot of the time, I played Mega Man with a Game Genie, gaining tricks like moon jumping and a super shot (which was really just all three shots firing at once). But because it was basically an intuitive way of hex editing, there were a lot of side effects too. In many cases, the audio would get a bit messed up. Funnily enough, I actually got pretty used to even (even the horrible squeals). It was so much so that, when I eventually got back into Mega Man in the later 90s and repurchased my collection, it was a little jarring to hear the true audio for a time!
Skip to today, and I come across this playlist by JoeRallyChampionship. It contains both the original and Game Genie altered music to Mega Man (like what you hear above). And in a strange, almost perverse way... listening to it is rather nostalgic! Especially the Wily stages; they gained an even more eerie and inhuman kind of sound. Makes sense since Dr. Wily turned out to be an alien, after all.
Do you think you could stand listening to game music run through a Game Genie? And do you have any memories of hearing the music like this when you played it? I'm interested to know.
