PicoPAC is a multicart DIY yourself based on cheap "PURPLE" Raspberry Pi Pico clone, easy to build and not expensive.

WARNING! "purple" Pico has not the same pinout of original Raspberry "green" ones, you MUST use the clone or you may damage your hardware.

NOTE: 3D files for shell are WIP and probably the PCB doesn't fit perfectly withous some cut/drill to PCB holes!! (Thanks to Mike Wilson for the Logo version)

Kicad project and gerbers files for the pcb are in the PCB folder, you need only a diode and a push buttons for resetting the cart if needed or want restart. Add you pico clone, and flash the firmware ".uf2" in the Pico by connecting it while pressing button on Pico and drop it in the opened windows on PC. After flashed with firmware, and every time you have to change your ROMS repository, you can simply connect the Pico to PC and drag&drop "BIN" files into. But remember that only games already in menu will be seen by the cart.

Even if the diode should protect your console, DO NOT CONNECT PICO WHILE INSERTED IN A POWERED ON CONSOLE!
