Attempting to collect udumper related information in one place. Udumper is a small executable that can be used to save a copy of ROM to disk on many canon powershot cameras. This avoids the need to blink the firmware out through and LED. The original udumper was developed by mx3, jeff666, grand and ewavr, as documented in this thread There is no official location for udumper, but recent source and binaries can be found in the latest version of cardtricks As of mid 2009, the current udumper does not work "out of the box" with recent canon cameras.
