Buyers must prioritize JAMMA (Japan Amusement Machine and Marketing Association) compatibility to ensure the board integrates seamlessly with standard arcade cabinets. Key technical factors include CPU processing power (e.g., ARM-based or FPGA for low latency), supported resolution (CGA/15kHz, VGA/31kHz, or HDMI/HD), and the number of supported players (typically 2-player or 4-player configurations). For modern multi-game boards like the Pandora’s Box series, verify the storage capacity (SD card or EMMC) and the cooling system efficiency to prevent thermal throttling during extended operation.
