Emulate ROMs At 12MHz With Pico2 PIO | Hackaday

Nothing lasts forever, and that includes the ROMs required to make a retrocomputer run. Even worse, what if you’re rolling your own firmware? Period-appropriate EPROMs and their programmers aren’t always cheap or easy to get a hold of these days. [Kyo-ta04] had that problem, and thanks to them, we now all have a solution: Pico2ROMEmu, a ROM emulator based on, you guessed it, the Raspberry Pi Pico2.
