    • Multi kit installation problems

      Hello,
      I received and installed a new multi kit last weekend on a SSFII gray rev 3 board and am not having much luck.
      Originally the board had died on me and almost sent the eproms out to Razoola, but sat on them for 16 years. I recently removed the battery and converted it to an AVP using 27c322s for the graphic and sound data, and had no issues. Everything was jumpered already matching the multi kit requirements.

      It was a little tricky seating the multi kit as the sockets were very tight, but everything lined up fine and did seat.
      The board navigates through the titles from the last Smokemonster pack,

      but most games do nothing, and only a couple show signs of life.
      1944 shows mostly a black screen with traces of graphics,

      but the sound and music seem to play clearly.
      AVP which works natively, does not. I also tried an unencrypted version.
      Xmen vs SF shows the most life but the graphics are all messed up. The text is unreadable, and each graphic plane is looks to be mostly single color.

      I have removed the kit and reseated multiple times, have used an old 50 pin scsi cable to bridge the boards, seated the b board caseless on the a, differerent SD cards, and tried both f and g pals.
      Nothing seems to change anything. All pins are intact, and I checked continuity on the rom pins from the top of the multi kit to the bottom of the b.
      I reinstalled AVP to verify I have not damaged anything, and other than firmly seating the a & b, it resumed operation.
      I am wondering if its worth replacing the program and graphic sockets.

      Any help would be appreciated.
    • Are those graphics kind of responsive or is something going on in the background?

      If you use a PAL F, you need to lift pin 7 of the PAL but if you use a PALG then it's pin 9. Which one did you write on that GAL?

      Try running decrypted romset first, like MVC Unlocked and let us know how it goes. @Mitsurugi-w

    • Both those games are running and responsive. I have a video of Xmen vs SF showing it in motion, but am not sure how to post it.
      I did both PALs lifting the corresponding leg. the image is the F, I started with it as a G with pin 9 up.
      I did try the unencrypted AVP I was running on the board prior to this with no luck, I'll take a look atMVC or Xmen vs SF unencrypted.
    • In that case, PROM is good, the interconnect board is also good and the problem is with some part in graphics of the kit. Have you checked that the jumpers on the B Board are good? Did you press the board properly but gently and look at it from the sides to make sure all pins go inside a socket?

      Posting some pictures will certainly help (use some external hosting like tinypic please).

      P.S. those cables for the key programming are a bit oversized IMHO. Are you confident that no solder blob has fallen somewhere in the PCB? Please double check.

    • Trying tinypic, and almost everything I send is failing...
      The jumpers were set properly for the AVP setup I used, and I did recheck after I had problems.
      The pins all aligned and are in the sockets. I will try to make a smaller gauge wiring for the key writing.
      I used what I could easily disconnect, I know it was a bit big, and It soldered pretty clean crowded on the kit attachment point.

      This, might be your problem. I don't remember now the AVP jumpers but you need to set them in a specific way as indicated in the Instructions, that I'm sure you've read ;)

    • Check connection between A and B (bent pins) and failing that, I had one here with a similar issue.

      I fixed that one by slightly pulling the IDC connectors on the multi kit away from the B board, it's still making a good connection and it's not going anywhere but I think pushed all the way in was causing enough flex on the board it was pushing the mask ROM pins out of whack.

      The other solution is to replace all the sockets since they're likely worn and causing your problems, but this may work.

      besides that, you can just isntall the B board onto the A Board without any plastic shell. That will make things easier.

    • Jumper settings dont actually matter. We need to remove that from the instructions.

      I see a red wire soldered to the gal chip but a grey wire connected to the j17 pin on the multi. Did you splice those together? You have a revision 3 pcb so check the bottom of your b-board. If there is a jumper wire underneath from a pal pin to the connector you need to remove it.
    • OK, I tried adjusting height on the main kit board from the B via the 2 3 row connectors and if anything it decreased the sound quality. I have mostly been trying the B with out the plastic shell, but the A has been cased/unopened.

      @Mitsurugi-w The wire is spliced, there is no jumper under the b board.

      After all this, I did replace sockets 11-20:


      after replacement


      To make sure I did not break anything, I put AVP back in afterwards to test:


      When I reinstalled the multi kit, there was no change, it is behaving exactly the same as before the socket replacement.
      That being said, the main board did seat very smoothly with the new sockets.
    • I got a rev 7 board before the GALs showed up, and the multi kit worked on the first install and second power up (after reseating the A and B board). Everything I have selected is working.
      The multi kit was not playing nicely with my rev 3... Thank you for the help. Have there been other instances of early rev boards with similar issues?
