Given that the Pi Zero has just one USB, and its a micro socket, we added a modified, powered hub to the equation so it could accept joypads, keyboards and drives. If you want to switch the RCA output to PAL, open the Pi Zero's config.txt file (located in /boot) and uncomment (by removing the preceding hash) the following line: A quick change in the config file swaps it to a PAL signal, and we're bathed in glorious rasterised technicolour! When looking into the Pi Zero's config file it turned out that the composite RCA output defaults to NTSC (this'll be correct for some of you, of course). We tested it by shoving the wires into the SCART socket, and we got a picture! Kind of.Īs you can see, it wasn't quite the rainbow-tinged dream we were hoping for. Pins 18 and 20, for those who want to do the same, rather than assailing the phono socket. Buried within its 21 pins, SCART has a composite video input (and output, for that matter). Instead of connecting internally to the phono socket, we opted to make use of the SCART socket instead. Initially we cracked open the case and soldered a couple of twisted-pair wires from the Pi Zero's composite RCA output to the back of the TV's video input phono socket.Īfter some tinkering, it seems the phono socket or its PCB had some issues, which turned out to be a blessing. But there's also a composite video output available on the tiny Pi, so that's where we started.Īs we didn't want too many trailing cables or an exposed Pi Zero, everything is going inside the old telly. The stumbling block here is that it obviously has no HDMI input, and that's the simplest option for hooking up a display to the Pi Zero (using a mini-HDMI adapter, of course). So we took to the charity shop, and found ourselves a classic CRT! Without further ado:įlat screen LCD TVs are ten-a-penny these days, but we really didn't feel like that would fit with the theme of a retro video game. Now we've whipped you up into the prerequisite frenzy, join cstanton and me as we turn the Raspberry Pi Zero into a Mega Drive/Genesis, SNES, Amiga, Master System, NES and a host of other classic video game platforms.
