A wee while back I ordered a Pimoroni PicoSystem to try out. It’s a small handheld games console based on the Raspberry Pi RP2040 microcontroller, and it sports both classic joypad controls and a 240 x 240 16-bit colour display. I gave my first impressions in an earlier post. Here’s what I think after spending some time porting my Raspberry Pi Pico version of the 1980s 3D shooter Phantom Slayer to the unit.
