RPI-A-horizontal version-sharing project_retroarch open source handheld console

Introduction: I would like to share something I made a few years ago, using the Raspberry Pi A development board and the Weixue system to make a handheld console. The performance is better than that of miyoo, because it is slower to boot. Use esp32 to make boot animation. There is no esp32 part in this project. At that time, that part was drawn casually and the project was not retained.
