Can we get something going for the Power Shot N100?
Depends which parts of "we" you bring to the table. If you are a developer with significant C and assembly experience and a big chunk of spare them, then yes!
N100 is a Digic 6 camera, so substantial development effort would be required to support it. A first step would be to get a firmware dump, which you can probably do using the Canon Basic dumper:
