So I was thinking about yesterday, and what it's safe to talk about with respect to work. I'm gonna take *some* risk here, but ... essentially, I'm not a ROM hacker or an emudev. Those are hobbies. My specific talent is reverse engineering, which is a much more broad category.
Not all ROM hackers are reverse engineers. There are level editors, generic compression tools, script editors, hex editors, etc that can be used. Most emudevs are also not reverse engineers; instead they rely on documentation, test ROMs, and emulator source to make their emus.
In fact, that's how I made all my other higan cores. But my fan translations, and bsnes, that was reverse engineering. I have taken apart a good 30% of Bahamut Lagoon and completely replaced entire menu systems with my own code. When I started on the SNES, ...
The information was just *barely* past what the SNES developer manuals contained. I took us from opcode-accuracy to sub-cycle accuracy (clock edge accurate.) Every emulator since was based on bsnes: Super Nt, MiSTer, Mesen-S, etc. They all used my code and research.
But what got me noticed was reverse engineering the NEC uPD and contributing that code to Stephen Hawking's voice emulator. My hobbies, unfortunately, are just not profitable. Only Yuzu can earn money like that. What the head hunter wanted with me was reverse engineering mastery.
