Unless you are interested in recreating a Sinistar game for persol historic reasons, DO NOT build a real sinistar game. Now if you are restoring an existing Sinistar cab - that's different. A real working original game has value both astecticly and historicly.
However, the PCB, video deflection boards, sound boards, power supply and monitor you will need is nothing short of very difficult to maintian. I know this as I used to do this. For FUN if you believe it.
Build your cabnet that looks like a sinistar cab, but throw a PC running MAME in it. Trust me - much much easier and cheaper.
