looking for GH1 "hacked" firmware

[khobar95]

Hi folks,

I'm new here, so apologies in advance.

I have a GH1, and I want to use it as an allsky camera. I have a wide-angle lens that works really well, but I have no computer control over it. I've used it with a simple timer/shutter device, but I'd really like to connect it to a Raspberry Pi.

I understand this is possible via a hacked firmware, but this camera is so old that I can't find anything beyond Ptool.

So, is there a source for the relevant firmware that would enable full USB control?

Cheers!
