But then again, thinking about it some more, if the multi can already accommodate a B21 why not just have them included by default pre installed into the multi and omit the need for a separate C board entirely?
I imagine there are not enough NOS B21 chips available for purchase. Even if there were, that would unnecessarily drive up the price of the kit.

Yeah - that sounds pretty cost prohibitive, if feasible. There has been a lot of debate about the true number of B-21 chips found in the wild. While some claim it was in the tens of thousands, I've seen others with evidence that it was in the hundreds. Even at that rate, there's no telling how many Darksoft bought.

Compressed air good or certain alcohol with q tips or none of the above?
Yeah definitely needs a clean. Plays well though, got it in advance of the Multi. Can you tell if it has that battery b-21?
SF2CE is the batteryless version, so needs some rework

Arg. Ty. Outsource things I need soldering anyway.
Any else that was mentioned that it was good or bad for? Thanks for the info PP
You heard what the boss said. Update my place for two kits when these finally drop.

@Darksoft well, I for one vote to wait so that [ if you are unlucky enough to have a battery-less C board] transferring the B-21 chip isn't necessary. It is delicate work on 2 expensive pieces of hardware that I prefer to avoid if possible. If it's unavoidable then hey, that's the nature of the hobby and it's the risk you take but I feel It would benefit both parties the most in the long run to just wait [until you can finish whatever alternative you are reconsidering].
Unless I have this all wrong and the alternative is to only use a battery powered c-board then i guess it is what it is and just ignore me.

Sorry @Frank_fjs , responding to this. bad etiquette on my part.
I created this thread just for you: What Donor Board to use for the CPS1 Multi
it might also be possible to modify these battery-less B-21 boards so it's worth attempting that before removing the whole thing.
I think that we'll give up on the transplanting option and although it's implemented we may remove it in the final run. Too much trouble.
You will need just a battery powered C-Board or one that's converted. In any case the kit is ready so that we can also allow for any other C board and have the addresses translated on the go....We're listening to you guys.
'Best" option IMO would be a universel C board (repro?) to go alongside with the kit as an option if you don't have a battery B-21 board.
I for one have about 6-7 CPS1 boards and NONE are on the C board with battery.
Not sure how big your stash of B-21's is to make something like this feasible?
But otherwise I foresee a lot of killed or scavenged OEM games by people who don't have the know-how to do so.

Once you guys figure all of this out, that's what I will do.
CPSI Multi Here I Come!
Of course, I have the SFII CE board, but oh well...

if it's implemented you might as well leave it implemented, it's a nice option for those that have the skills and access to a donor chip, Just leave it as an undocumented/unpromoted feature.

Hopefully the modification to no-battery B21 boards becomes realistic, because that's all I have right now. Will happily pay someone to take care of that for me.
Q-Sound board is the "D-Board", it's an additional PCB sandwiched between the A and B boards (so the board stack goes from bottom to top: A - D - B -C)
The boards are named after the model numbers silk screened on them.
For instance on a Punisher PCB stack (Which is a CPS1.5/Q-Sound Game)
A-Board: 89626A-4
D-Board: 92636D-3
B-Board: 91635B-2
C-Board: 92641C-1
technically the filer board on a Q-Sound game is the "E" board because it has the number: 92636E-2
