Hello. I'd like to inquire about the huanted castle pcb. I understand that there are many of Konami substrates that support Stereo. I wonder if this huanted castle pcb supports Stereo. Among them, there is a connector called svcn4p, and I wonder if this is the connector that supports Stereo. Or I wonder if this pcb is purely mono pcb. I apologize for my English. thank you!
