Custom firmware finally booted!
I'm not sure what I did differently this time, but for some reason the camera finally took my modified firmware. Unfortunately, the routine I modified was so slow (it beeped) that the camera reset itself before it could finish - so it just beeped continuously for several seconds, paused, and started again. Fortunately, USB mode still worked great. I got a few beeps everytime I started a USB operation. Kind of cool. I can't explain why it refused to boot before now, though. Maybe the camera was just being stubborn? Anyway, I'm going to try for a more invasive mod next - and see if my luck holds.

Hey, that's great! Once I get some issues worked out I will try to start coding myself, I've a little bit of ASM and some C. Is there a size limit of the firmware? Since it goes in the flash memory, i would doubt it but I am probably wrong.

Of course, there is nothing to say you can't add additional binaries if you need the room - but then you have less space for pictures. I have a build system that basically creates the banks as individual blocks of code, then does a copy /b core+bank0+...bankA. Of course, Bank A is just filler and the checksum data.
