This video is the first in a series to show you how to get started with using One ROM, the most flexible replacement ROM for your retro system. In it I cover all of the major hardware features, including how to identify pin 1 and install the legs and header pins.

Future videos in this series will cover programming One ROM with your chosen ROM image, how to install multiple images simultaneously, more advanced configuration, and features specific to certain One ROM variants.
