CHDK specialitiesEdit

Due to the camera's keyboard layout, CHDK for the SD780 uses the following key to enter <ALT> mode :

1. Press Playback (the blue triangle in a blue box) key shortly for enter/exit <ALT mode>, press Playback key longer for the camera's original function
2. Alternatively, the <ALT> key can be set from the CHDK menu to be the DISP key

Firmware dumps

Progress:

• Camera responds to encoded DISKBOOT.BIN on bootable FAT16, but UDumper (NewDryOS) from CartTricks 1.44 does not write on card.
• Camera will boot PS.FI2 file. Have discovered first LED.
• AF LED found. Blinker circuit built; initial tests look good for first attempts at blinker firmware dump.
• FW dump complete - will find home for it shortly.
• Initial port underway.
