Is there someone having a working Konami Silent Scope 2 (ROM's marked '931') who is able to give me a dump of the M48T58 NVRAM code to resurrect my dead board ?

Hi, the problem ist not the chip or writing the data.. it seems that there's no one who has the NVRAM data available to share for the Silent Scope 2... I know someone who seems to have the data but requests a lot of money for the repair which I am able to do myself but I need the NVRAM data first from a still working board...
dark silhouette has a small little pcb board that sits on top of the main cpu board. I swapped all the roms and put that little board on and it now plays dark silhouette.
All I did was change out 4 eproms that were on one board to make it ss2. I had to leave in another 4 eproms on a second board to make ss1 work. Its kinda hard to explain, silent scope 2 will still work with the 4 eproms on the second board in place or removed. It didnt matter. silent scope 1 HAS to have them 4 and the other 4 to work.
Yeah, I was curious about that as well.
I know a fella that has SS2 running on an SS1 boardset with only the swap of 4 roms as best I know right now. He made mention of a small pcb also, but I'm trying to clarify which board exactly. So I'm not sure at the moment if the NVRAM chip was swapped somewhere in the process or not. (I'm not familiar with the board layout on these)
He's too far away for me to just run over and look or grab the boards to borrow.

Let me know if you need another boardset to use for a proof of concept test once you think you have it figured out, I have 2 sitting collecting dust![]()
maybe he's willing and able to just dump the M48T58 chip (the NVRAM) - that would already be a major step.
He doesn't have the capability at the moment.
But I'll get whatever information I can from him about his boardset.
So is the NVRAM chip ... NOT ... on that "little board" ?
(guess I ought to look up a picture of the boardset so I can familiarize it's arrangement)
