The zoom now works properly on 100c. I'm not sure if the camera is supposed to have an AF feature in video mode. If it does, I'm not sure if it works.
I've tested some override features and so far, everything seems to work as it's supposed to. I've done a 8-minute night-sky exposure without problems, as well as tested extremely short shutter speeds, which seemed to work. Not sure if anyone really needs anything quicker than 1/10000, anyway, and that definitely worked.
As for aperture override: this depends on the zoom. If fully retracted, it doesn't go beyond F/8.0, but it can go up to F/16.0 when fully zoomed in. I didn't do any tests in-between, but I suppose that the maximum and minimum aperture change according to the lense's specifications.
ISO override didn't seem to have any effect outside the camera's range. So even if it said that the photo was taken with ISO 12 or ISO 64, the photo was basically exposed at ISO 80, and when taken with ISO 5000, the real ISO was still 3200.
What seems bugged to me are the games, though. Reversi seems alright, Sokoban doesn't start at all and the colors in Connect 4 and Mastermind seem unusual.
Oh, and another thing: the camera will not take a dark-frame if the normal exposure is below the limit. Meaning that if you set override to above 1.3 seconds, but the camera's setting is below that, it will skip the dark-frame.
