That would have been only a little before a1ex left. Getting code running on real hardware is easy, maybe I'll talk to you in discord in a few months when you find this fabled free time we are all looking for ;)

The 4000D is an interesting cam, we've had a few people start ports then give up. It has a mix of old and new parts in the software. Canon used an old CPU / ASIC: https://en.wikipedia.org/wiki/Template:Canon_EOS_digital_cam...

So it has hardware from 2008, but they did update the OS to a recent build. This is not what the ML code expects to find, so it's been a confusing test of our assumptions. Normally the OS stays in sync with the hardware changes, which means when we're reversing, it's hard to tell which changes are which.

That said, 4000D is probably a relatively easy port.
