Double Dragon MCU Image (Taken from a bootleg DD PCB)

This rom was located on a daughterboard that
was plugged into a 63701 socket. On the board was several
TTL chips and one rom containing the included image.
When the PCB boots up, it proclaims that the 63701 is OK.

I don't know if this image is useful to fix the needed MCU image
of Double Dragon.
