Nowadays, Powkiddy A12 game machine is gaining popularity. There are very few game machines with 9-inch displays, arcade sticks and buttons at the price of $60, so they are getting high scores for not only cost-effectiveness but also completeness.
However, in A12 arcade games that require performance are somewhat unfortunate, such as falling frames.
That's why I started this DIY because I wanted to port the Raspberry Pi 4, which runs the Dreamcast game perfectly, to make it a more complete game machine.
Even if you try to get only the case and 9-inch display, it will cost you $60, so making a bartop with the Powkiddy A12 is a price-worthy task.

(In this video, 2A step-up module was used, but a reboot occurs due to insufficient power. I upload the link back to the 4A module. But it is recommended to step down with a 12V battery. Battery production tips: • 라즈베리파이 4로 노트북을 만들어보자! ... )

* The battery that can be selected at the time of purchase has a low capacity, so a reboot or no booting may occur when I use it. It seems that there is not enough capacity to turn on both the Raspberry Pi 4 and the monitor. I think the battery needs to be stepped down to a 12V battery or use 4A step up module.
