The Pico is *very* overclocked, from 150 to 325Mhz. Not because of the sampling (although it helps!) but due to the required resolution on the DVI port (1024x768 for pixel perfect doubling). Sampling it entirely made with PIO, the CPU is just handling DMA interruptions to adjust read and write addresses. Tried a few implementations, most CPU based, but this was the final goal, and it works beautifully!

Next steps are cleaning the code and pushing to somewhere public. Maybe it’s a good opportunity to try Codeberg? #RetroApple
