Ricoh GR - Firmware hacking

Hi Guys,

I think that this camera is amazing, but I'd welcome some more customisation options.

  • custom mapping of all buttons.
  • customised folder or naming
  • other tweaks which could be done via software update (list yours?)

So, I'm exploring options on altering the firmware and found some resources: (slightly updated code in my repo:

Long story short: I am not sure if Ricoh is going to update this camera range or release any great firmware updates. It's a great camera which could be amazing with some little tweaks. Some of the wishlist items could be theoretically achieved by some tweaking of the software. To do that:

  1. We need to be able to decompile correctly the available firmware
  2. be able to alter it and connect what changes affect which functionality
  3. be able to compile our own version

The code I referenced on top is not 100% working (some code is readable, some is still obfuscated, so additional work will be needed). I am regrettably not a crypto analytic, but I can code, so once the above 3 points are sorted modification of the code should be quite straightforward.

I am posting here to see if there is support for such an idea and endeavour.

If yes, and if there is someone with such skill set available in this sub willing to work on this, then great. Otherwise we could post a bounty / ask on other subs or websites for help.

I've quickly created a small survey to see how many of you would like to support this:

So, let me know guys what you think!

Cheers, Jokob
