In this video about One ROM, the world’s most flexible and powerful replacement ROM, I show you how to program your One ROM using the simple, yet powerful, CLI. I cover the CLI on Mac, Linux and Windows, including how to analyse and program One ROMs, peek and poke ROM data, and also provide a sneak preview of an exciting upcoming new feature - reset your host systems directly from One ROM.

This video is part of a series to show you how to get the most out of One ROM.
