OK, so it's at 0c10.0000

You fixed the entry point address, but you still use the incorrect
load address.  The program cannot run if you load it into some
unrelated memory region and then jump to some totally different
address.  You must use the SAME address (0c10.0000) for both the -a
and -e options.

Best regards,
