Is it true that some of the games old/classic/used /new games require some adjustment in voltage than recommended +5 volts?What about HGA ?
Yes it is true that many games need adjustments in voltage,Either they need more voltage or some times less voltage than recommended +5 Volts.The HGA is equipped with a adjustable heavy duty power supply with a small knob/pot located on the front section of power supply and the voltage can be increased or decreased easily by varying the pot/knob to a desired level . In Most of other Home Arcede systems there is fix power supply and Voltages cannot be increased or decreased or adjusted manually how ever in our system the voltages can be adjusted easily.
