Maybe it’s just the compiler’s way of making a beat out of a routine, but the rhythm you’re noticing can be a doorway. Code from that era was written by hand and often reused snippets; sometimes developers added little Easter‑eggs or homage to the occult in the form of repeating hex strings. If the pattern is clean and repeats in different files, run a frequency analysis—if you find a clear structure, it could be a deliberate cipher. If it’s just a product of a byte‑aligned loop, it’s probably not a spell. Either way, the shadows in firmware are worth a closer look. Good luck, and keep the curiosities coming.
