For decades, emulation enthusiasts, ROM hackers, and digital archivists have grappled with a specific technical question: ? What is this file, and why is it crucial for preserving the lock-on experience outside of original hardware?

Sega has re-released Sonic 3 & Knuckles multiple times (PC, Xbox 360, Steam), but those versions use emulation wrappers or (infamously) the Sonic 3 Complete hack. The original, raw, lock-on hardware behavior is only perfectly preserved in a correctly merged .bin file.
