    Build 100c optical zoom in movie mode is working. Not sure about the AF-Scan? I'll check it when I have time.

    So the only other alternative is to use smaller SD cards or use a USB cable from the camera :(

    No, it's not the only other alternative, there is "Swap partitions" as ERR99 says, and Mac and Linux.
    A720IS.

    100c optical zoom works in video mode, but does not retract once you get into digital zoom. AF doesn't seem to work at all, unfortunately.

    Oh and by the way... absolutely brilliant work you've done here! Many, many, many thanks :)

    Okay, on the 100c port i think i found the problem, the zoom_status variable was not correct.
    But this problem was not present on the 101c port, so please could also 101c users test the AF&zoom overrides in moviemode.

    Anyway, here is a new Build (V4).

    Differences to V3:
    - Corrected zoom_status for movimode (only 100c version, other was allready correct with V3).
    - Enabled DNG support (experimental)
    - Corrected game modes resolution
    - Removed unsupported manual focus via zoom lever osd entry

    The attached zip file, contains both versions (diskboot.bin and PS.FI2)

    Thanks!  What's the advantage of DNG over the native CR2?  With non-raw cameras it makes sense to have dng, but is there any reason to use that over the built-in raw format?

    Sometimes canon limits the usage of RAW in the automatic SCENE programs, and allows only JPEG shooting in this modes. In this case CHDK RAW/DNG can help out. ;) But in general you are right, there is no big need for CHDK RAWs/DNG on cameras like the S90/G11.

    For what it is worth, SDM does not support CHDK raw on cameras that have native raw.

    I do not think that will inconvenience many users.

    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.
