@JohnRambo'sKnife So it’s not worth it to purchase Brook Retro Board now and try to use it with Jammaizer? I have Console Jammaizer v2 but I have never used it. I was planning to do so but wasn’t sure which add-on board to get. What options do I have at the moment?

I burned another EPROM for sound ROM 08 plus flashed 04 and 05 for sprites. Then I did lengthy testing session afterwards. Sprite issues are now fixed which is great 🙂 Other issues mentioned remain as before though, mainly no sound.

Here are some pictures of my original main board and rom board. Main board is M92-A-B and rom board M92-C-B. I will look into sound EPROM again. And maybe flash 04 and 05 one more time just in case.

Yes, I moved those jumpers to N. Programmer I used is SuperPr 610P Universal Programmer. I updated access rights to my videos. Please try again.

Hi @Mitsurugi-w @Ape Cosplay I'm just now back to troubleshooting my problematic multi installation that I posted about earlier in thread. So after lot of troubles before especially with no sound I tried my donor board in orginal form as Thunder Blaster and sounds works just fine. Today I...

Btw I just tested Thunder Blaster board in it’s original configuration and it’s confirmed that everything is working. Sound is fine too. By doing that I accidentally bent and broke 2 pins from FIX daughterboard so gotta figure out next how to repair that ?(

Sound daughterboard connection to the ROM board seems fine to me. Pictures of that in above posts. I took few more pictures of sound daughterboard. I also switched another FFC cable in for test but it didn't help.

Here's a picture of my jumpers. Both J1 and J2 are on N. I also switched sound EPROM to newly programmed one. Still no sound.

I don't know what's the fuzz on that picture but here's how the connector really looks. No bridging.

This is overview of my multi board.

This is solder side of sound EPROM socket in multi board. Could that tiny bit of excess solder on top of via be the cause of sound problem?

Do you mean Sound EPROM? I haven't cleaned ribbon connectors. I can do that. Yes, my ROM board is M92-C-B.

I checked sound daughterboard connection and reattached all the ribbon cables one more time. To my eyes everything is installed according to instructions. After the process above there's still no sign of sound but I didn't encounter graphical glitches anymore. I took few pictures when I was at it.

@Mitsurugi-w when you said "I'm seeing a similar issue with another LT donor currently" which of my issues you meant exactly?

Yes, I closed the jumper in Multi like instructions told me.
