That's awesome! I have a few suicided CPS-I games that I would love to have back to factory spec so to speak. Obviously I will not need to use them because I will have the multi, but it is just an OCD thing....haha

I have a 92641C-1 board that has the trace cut across to pin 47. As I understand it, a fix that can be done is to bridge 45 and 46 to 47 to give them a ground connection again. Is pin 48 also ground? If not, where would I connect these 3 pins to so ground is connected again.

Did this happen and I missed it?

I have a modified 92641-C -- will this work as-is with the decrypted set, or do I need to follow the "In order to modify a C Board that has been patched to work without battery, you need to do the following" instructions?

If it's been modified (has a patch wire) then the mod needs to be reversed before it can be used with the Multi.

I have this board, I looked into my board and I do not see any modification done to it (it doenst have a battery) its currently running SFIICE, do these boards require no modding for operating the game baterryless? Can I just plug that in (as is) for CPS1 Multi installation?92631C-6
These "Good" Options will work, however you will be limited to only using "decrypted" ROM sets.

Yes, that board will run the decrypted set without issue as is
Exactly that, but you can't use it as it with the multi. It will only run decrypted games.

That board as is will only work for games which use the CPS-B-01 PPU2.
It simply "happens to be" what people call "decrypted games" because B-01 is the most common PPU2 variant the hacks target it.
Because it is the B-21 chip it can be modified to behave like a battery board. But that is a bit advanced require traces cutting and pin manipulation.
