G9 1.00F - zSHARE - bingo_bongo_g9_firm_vergm1_00f.7z
Well, bingo_bongo has precedence. My dump of G9-1.00F is here: [URL

I wouldn't mention this except that (1) b_b's firmware doesn't start until byte 0x09BE00 of his file, and (2) once the leading and trailing zeroes are scrubbed off, DIFF says that there's a difference between the two dumps -- though I can't get it to tell me where the difference is. I'm wringing mine out in IDA with an eye toward porting. Boy oh boy! The tools have gotten way much better in the 30-plus years since I did any of this work. (Anybody want an IBM S360AL disassembler written in FORTRAN? I have the card deck around here somewhere . . .)
If anyone has the knowledge and the time to determine where the two dumps differ, I'd appreciate knowing. There may be a chance the IS (Image Stabilization?) software changes independently of the "firmware version". My camera has "IS Firm Ver. 3.00" and "IS Param Ver. 2.03".
Thanks for considering this, and thanks very much for initiating and continuing this project.
