I don’t like the raspberry pi solution. 1) I didn’t want to drill more holes in the cabinet. 2) I didn’t want over saturation of games. 3) I only wanted arcade games (I have other systems for those games), and 4) I wanted a plug and play option, no computer setup. No learning curve.
I decided on the Pandora’s box 5 home edition. You only need a controller for the lcd screen. The A1up power switch can turn it off and on. It can be put on free play, don’t need coin buttons, and a long press of player 1 start brings up a menu to exit the game. No need for exit buttons. The Pandora’s box has over 2000 games, I trimmed the list down to the best 30 fighting games (it’s in a sf2 cab).
The arcade1up power supply works for the Pandora’s box. You can get a second power supply for the monitor, or buy a 12v 6A power and run both off of the same power supply.
