Not sure about this one.
The board is good for nothing, looks like its had liquid spilled on it a long time ago and there is green gunk everywhere.
There is not much on the board that works but this GAL appears to be unlocked.
Its a GAL22V10 found on the daughter board, it may come in useful for someone.

On the motherboard of the System 16B there is a couple of PLDs.
315-5213 is a PAL16R6, mine is locked and im not going to attempt to reverse it
315-5214 is a CK2605 chip which I have dumped and converted it to fit in a GAL16V8 device. I have confirmed this is working.

My friend Runik is currently in the process of creating decrypted ROMs for SEGA games that use the FD1094 custom CPU.
If you are able to test them on real hardware then please give feedback.

 

To use simply (re)program the relevant eproms with the ones downloaded and replace the custom CPU block with a normal 68000 CPU.

There is a PAL located at U9 and marked as DEC402 (on my board) inside the BM4000 unit.
I have dumped and tested this PAL.
Without the PAL fitted I got no boot up and an almost yellow looking screen with some lines through it

There has been a bit of work done recently with the bootleg version(s) of Bubble Bobble (Bobble Bobble).
The story can be found over on the Arcade Otaku forums, https://forum.arcadeotaku.com/viewtopic.php?f=26&t=5154

Basically the joaoljr has added the code found in the MCU of the original pcb into the ROMs of the bootleg and it has resulted in what is almost, if not completely perfect Bubble Bobble. Title screen and all is restored.

I did take a picture but it can out horrible so I wont add it but it does work.
Thanks to joaoljr for doing this patch.
