Instead of flashing a NES rom to the Pico using picotool, you create a FAT32 formatted SD card and copy your NES roms on to it. It is possible to organize roms into different folders. Then insert the SD Card into the card slot of the Pimoroni Pico DV Demo base.
A menu is added to the emulator, which reads the roms from the SD card and shows them on screen for the user to select, flash and play.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound.
