			update 20170615 from Caius:<br>
			As stated in source, sound hardware is totally different from the original Sega System 18.Bootlegers used a single OKI MSM6295 PCM chip for both samples (stored on two device) and BGM (stored in four devices).Pin 7 of the OKI is high (tied to VCC). Clock on pin 5 of the OKI is @ 1 MHz. H-SYNC should be around 14.84 KHz but I'm not really sure, I can see board has some SYNC issue maybe due bad design.V-SYNC is measured @ 58.271 Hz (using an EL4583 SYNC separator with low-pass filter applied). Back to sound: it seems BGM is missing a track (at least music of first level).You can notice it by ourselves looking at this video I made and comparing it to a MAME or original PCB recording: https://www.youtube.com/watch?v=ZUOEtbNiTNk&feature=youtu.be I can't see any faults on PCB so I think this is a limit of the re-engineered sound hardware (like it happens for some CPS1 bootlegs). Maybe we can ascertain this if sound will be hooked up in emulation (currently it's missing). Lastly : there are three PLDs on PCB (one on CPU board, two on video board).All three are secured GAL16V8 and two of them are registered too. I was able to reproduce only two: a combinatorial and a registered with simple logic.The third is a registered one which use a strong feedback.
