Can you guys chec the following?
The instruction manual says you can output stereo through the jamma edge. on my board you have to enable the following jumper.
Heres the manuals pinout for the jamma edge, so pin 9 should be the right right channel.
I already decapped my MB, so cant test, anyone care to try?
Im not 100% sure if the games themselves output stereo sound though.

I cant test it out, I decapped my mb already, waiting on replacements.
I traced out he sicrcuits and the dac does have both traces for the L/R outputs going over to the amp. And the amp is not wired for mono output, so I think it does output in stereo, but again, is the games dont output stereo sound, so not point digging into if its still mono sound.
At the moment Im more concerned with looking into replacing the volume pot with something more decent, but cant seem to find a suitable replacement.
Just replaced my caps with @Derick2k’s cap list and sent him some notes. They all work but a few could have different pitch to be perfect.
The main cause of my sound issues was of course the potentiometer. It is a stereo b103 pot and thankfully matches the footprint of a Gameboy Advance volume pot perfectly, you just have to bend the pins to fit through-hole instead of surface mount. New pot on the right, above, works great.
Hey guys do you think this might work for a replace?

What symptoms are you seeing?
I wrote up some docs on what I saw when trying different failure scenarios

Oh
I was just following that.. you wrote it hehe
One of them is displaying a single vertical line on the right, on power ds1 lights, then ds2, then both togheter, and it repeats (just like you said). So maybe its sdram (i have ordered few sdrams on digikey, 4m x16).
The second one i was suspecting the mosfet was bad because Vin and Vout were bridged and the board was not booting at all (no leds). After changing it i had the same issue until i have decided to remove the sdrams and the bridge was gone. Un fortunatly one of the sdrams pads was complitely ripped off when i removed the one near the jamma connector and i'm afraid that wiring patch will be a pain the arse to do, so ill just try with the one that is at least booting.
I've also made sure that the vzero was properly soldered with a digiscope.
If changing the sdrams wont do ill try the 256 ram near the socked bios but other than that i dont know what to do else

Just received the board today. All games work but I have also the fast moving Wuly thing. Great stuff.
@ekorz figured out a fix for Wuly Buly, go into test mode (either with dip switch 8 or using the test button on your cab/supergun) and reset to default settings.
Wow, thank you for your patience waiting for it to arrive. Glad it finally arrived!
