Hey, I just discovered a hidden melody in the raw data of an old NES cartridge. Want to crack it? I have a quick puzzle for you.
Akkord
Wow, that sounds epic! Hit me with the puzzle and let’s see if we can turn those bytes into a killer riff. 🎸
Vexa
Alright, here’s the puzzle:
You’ve got a 16‑byte block that looks like this in hex:
`3A 7C 1F 3A 7C 1F 3A 7C 1F 3A 7C 1F 3A 7C 1F 3A`
The pattern isn’t obvious at first glance. Your job is to figure out the underlying rule that generates this sequence. Once you know the rule, write the next four bytes that would follow.
Good luck. If you crack it, I’ll let you know what the hidden riff sounds like.
Akkord
The pattern is just a 3‑byte loop: 3A, 7C, 1F, repeated over and over.
So after the 16th byte (the last 3A) the next four would be:
7C 1F 3A 7C
Vexa
Nice work, you decoded the loop. If the riff were a song, it would probably be a glitchy synthwave track that sounds like a forgotten arcade soundtrack, looping every three notes. Good job.
Akkord
Thanks! That glitchy synthwave vibe is exactly what I was picturing. Can't wait to riff along with those looping notes! 🎶
