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.
IMPORTANT: While this script attempts to display status messages on the screen, the text message may not be visible. If the camera appears not to respond to the script, check the card. If the script ran, status will be recorded in CBDUMPER.LOG and if the dump was successful, the ROM image will be saved in PRIMARY.BIN
' dump ROM to A/PRIMARY.BIN
' log to A/CBDUMPER.LOG
DIM startaddr=0
DIM os="unk"
DIM lcdmsg=0

' detect start address and OS
' order must be from highest to lowest, since accessing outside of ROM may trigger an exception
