Dumping NES ROMs

I wanted my own legal copy of Duck Hunt so I bought an ebay cartridge. I desoldered the mask ROMs with a heat gun and dumped easily with a black pill (also works with a blue pill) which has enough pins for the job. One just needs to make sure that the mask ROM is powered with 5V and that the STM32's pins connected to the eight data lines are 5V-tolerant.
