This video covers the new One ROM v0.7.x firmware - now available - explaining in depth what, why and how I did it.

It covers the new architecture and its benefits, including fully automated regression testing for all ROM types, all hardware variants, the plugin APIs and regression testing the main shipped plugins. There’s also a run through of the new v0.7.x+ web programmer. Along the way you’ll also learn about RP2350 PIO emulation, One ROM Lens and One ROM Lab.
