I picked up a pcb from @Krmnnghia to try and get it going.

Using RBI baseball daughter for testing.

Game plays 100%. Audio is good, it's on master side of pcb.

Tested daughter in another pcb so we know it works.

he did a great job replacing super shitted up sockets. I removed them just in case and reinstalled fresh ago. No change.

There has been some past work on this board. Scrutinized under glass and didn't find anything broken or cut.

Wondering if anyone has any pointers on which part to look at for this ? I was going to install my working SMB set to get daughter card out of the way for troubleshooting also.

Thoughts?

Anyone ever tried these sockets on vs. ?
Wondering if the lever action will help the daughter board pins to not absolutely destroy the socket for anything but the daughter card.


Price is right. I bought a couple last order for shits and giggles, this may be the time to try them out...

Those look slick! Curious to hear how they work out.

Did you try the RBI on the other side?

Im just concerned that they will simply just smash the middle red part in just as far and destroy the sides, but will give it a twirl.
Worst case, could get crazy and shave down the leading edge a bit on the red so it would be reusable for daughter board games only, but put less pressure on thicker pin and hopefully not smash it up ?
 
You can't use SMB by itself on
the main (left) side only. It has to be installed on the right side if it's solo. However, you can use SMB on the left side with the RBI DC on the right side.
I have it running on the left side with dummy CPU on the other side. Sockets on the other side are super shit so trying to get this side fully working.
