MX29LV320

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

Then insert the 29LV320 flashrom into the TSOP48 ZIF socket, plug the ZIF socket into middle position of the 8bit flashrom adapter and finally plug the flashrom adapter into the cart reader.
The two SMD switches do not matter in this case as they're only for the SOP44 slot.

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.
