With apologies if it is already mentioned somewhere in the wiki, is there a camera simulator somewhere?
(sounds difficult and time consuming to code blindly and test only from the real 5D2)
[ Of course something like the iPhone simulator provided by Xcode would be great, but it's probably too much to ask :) ]
G3gg0 has a simulator that can run the boot process and start a few tasks - it even intercepts some debug messages.
We only test on the real cameras.
