Thanks for posting the dump. I haven't looked closely but I'd expect it's quite similar to g7x2. It does use a different DryOS version: 59p3, as opposed to 58p10 on g7x2.
We haven't ported any other digic 6/7 cameras with this exact version (also used on M5 and M6), but M100 and SX730 are 59p4 so both earlier and later have been ported.
