I recommend at least a 32 gigabyte of SD Card and I’m going to use 64 for this blog and we also need another computer to install the Raspbian Image to the SD Card. You are obviously going to need a Raspberry pi 4 1,2 or 4-gigabyte model that will work.
This method should get a lot of people up and go until retro pie officially releases their retro pie Image for Raspberry pi.
So we have to install Raspberry Pi OS and then install Retropie inside of that Operating System. This is a bit different from installing just a retro PI Image to an SD card. Here again, Today I’m gonna show you how to install Retropie on raspberry pi 4. Install Retropie on Raspberry pi 4 (Inside Raspbian OS)
