Universal dumper

VxWorks and dryos compatible dumper. Log file records status, start and OS. Shows how to safely call event procs that might not be registered. If this doesn't work on your camera, you can try the original.

note This script attempts to display status messages on the screen, however, they may not be visible depending on the colors used by the camera and the image displayed when the camera is run. The status messages are also logged to CBDUMPER.LOG in the root directory of the SD card. After running the script, inspect the root directory for CBDUMPER.LOG and PRIMARY.BIN. Adding LCDMsg_ChangeColor(a ,6) on the line below LCDMsg_SetStr(lcdmsg,msg) in the private sub PutMsg(msg) makes visible the status message on the screen (in orange) for the S95. (from Hello World script info)
