Canon G9x mark II firmware dump

I made a firmware dump from G9x mark II Ver 1.00C. https://drive.google.com/file/d/1GRClsB7TCDB4Ryonfk5TvDWSs37eizlZ/view?usp=sharing

CamInfo_Debug(1) works as well with G9x mark II.
I would be interested to know how big the differences to the firmware of the G7x mark II are. I'm not sure if I'm ready for porting yet ...

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.
Don't forget what the H stands for.

Greetings!

I have got a g9x mark 2 myself. And...  I can't make a firmware dump from it.

How have you managed to run an  .m script? What to press for that?
Is it a generic DryOS script or something special is required?

Thank you!

Once an SD with this format is inserted on the Camera, "extend.m" is called when the camera is in playback mode, by pressing FUNC./SET.

i will try again.. Maybe the problem that my SD-image is an old FAT16. I will try FAT32.

It doesn't work every time for me either. I would start the camera several times.
