It doesn't work that way....
If you need your pcb eproms redumped then you'll have to send it off to an arcade repair guy. Check the net, but it's best to find someone local if possible.
If you meant you own the pcb so now you have the right to play the rom in mame then think again. Backup copies of software extracted from hardware (which can be loosely linked to "bypassing protection") violate the dmca, and therefore, contrary to popular belief, owning a pcb does NOT give you the legal right to make a backup, or use it for that matter.
