The gains come from pairing Ghidra with a coding agent. It works amazing well.

I'll second this. I used opencode + opus 4.6 + ghidra to reverse engineer a seedkey generation algorithm[1] from v850 assembly. I gave it the binary, the known address for the generation function, and a set of known inputs/outputs, and it was able to crack it.

would you have a tutorial on that?
