This is due to the double layer board design of the Hyper Neo Geo 64. Correctly powered boards will display a blue screen with white text as the board and game boot up. If not powered properly, only a blue screen will be displayed. The board has four versions: one which only plays the four fighting games; one which only plays the two driving games; one which only plays Beast Busters: Second Nightmare; and one which only plays the two Samurai Shodown games. The fighting game board has two revisions. While looking like one, the first revision is not true JAMMA, as the sound does not come from the JAMMA edge but from a JST VL connector mounted on the front of the board, which is controlled by a potentiometer. There is a modification available to get mono sound off the JAMMA edge which involves removing a jumper and setting another. There is also an extra +5v connector that is supposed to be connected to the back of the board to "prolong" the life of the board per SNK. It is still unconfirmed if having the extra +5v connector connected actually does increase the board's life. Some say it is to divert the heat of the high amps going through
