* The sprite ROM is twice the size as Laser Battle with the bank
selected using bit 9 of the 16-bit sound interface (there's a wire
making this connection visible on the component side of the PCB)
+ * If demo sounds are enabled (using DIP switches), background music
+ is played every sixth time through the attract loop
