In this One ROM tutorial video, I show you how to program your One ROM with a ROM image. I cover how to use the One ROM Web programmer software, how to select your ROM image and type, and how to write it to your One ROM.

This video demonstrates programming a 24 pin One ROM. The process is the same for 28, 32 and 40 pin One ROMs.

This video is part of a series to show you how to get started with using One ROM, the most flexible replacement ROM for your retro system. Future videos in this series will cover more advanced One ROM operations.
