MX29LV160

First you need to setup the Cartridge Reader Shield's config switches like so.

Then insert the 29LV160 flashrom into the 44pin zif socket, plug the zif socket into leftmost position of the 8bit flashrom adapter and finally plug the flashrom adapter into the cart reader.
You also have to adjust the two SMD switches both to the bottom position.

In the main menu first select "Flashrom Programmer" and then choose "8bit adapter". To program the flashrom you need to erase it, then do the blankcheck and finally select write to flash it with your rom.
While writing a rom to the flashrom the led should blink constantly until the flashing process is completed.
