Porting G3X

I recently acquired a G3X due to the focusing/zoom ring failure on my G1X2 (which leaves me no other ways to use M/Av/Tv, it was water ingression and the hall sensor cable is no where to be found on flea market).

I think if I were to use CHDK I could write some custom scripts to remap buttons and dials to be able to resume working state of that camera, but before I could look into it, I got a G3X, so now I have both cameras.

I have just dumped the firmware for the G3X, will take a look of what's next...

Got a bin now, let's see how to run this thing:

Code: [Select]
dance -> DISKBOOT.BIN ver 15
copy modules

Managed to create a bootable card and put the DISKBOOT.BIN in it, but not booting apparently.

Time to do some digging
