DARKSOFT CPS1 Multi - Support thread

I'm really scared to do that cause when I turned it on it smelled like burning and the chip was hot to the touch
 
I'm sorry, this is the best I got

When I reversed the mod on mine, the first power up I got smoke. I thought I had ruined the board. Second power on it worked. Your soldering looks good to me on that pic. So I don’t know.
 
So gave it another wack
Good news and bad, it works!
But now these weird vertical lines show up, what's up with that? (Homebrew thing but this happens with everything)

So tested the other C Board again, and sadly it seems that for one reason or another, the C Board is the thing causing the problem. It must've gotten damaged when I flicked it on or something
On top of that tried, running Punisher only for it to return a RAM ERR, I assume that's an A-Board issue? Ugh, today is not my day 😂
Thanks for the patience. I really dunno what to do now.
 
Got a new C-Board, all is good!
Only thing now is CPS1.5 games don't work, is there a list of compatible A-Boards? I know it says 1.5/Long Boards don't work but a definite list would be nice to have, got a few A-Boards I could try and would appreciate some more certainty before doin anything ya know?
Thanks for your patience
 
Good news. Can you show a picture of your cps1 setup? did you replace the pal on the motherboard as the instructions explain?
 
I did indeed, using a 89626A-4 A Board. Forgive me but I don't know what "Sound section is populated" is supposed to mean, I reckon that's why it doesn't work but honestly I don't know what to even look for. The wires are in the right places far as I know, it reset upon write and it hasn't exploded yet so reckon it's fine haha
Have a few other A-Boards, but any idea what numbers are confirmed to work or what to look for would be helpful, thank you
 
Sound section means the central part of the cps1 multi where a tiny sub pcb is inserted.

For compatibility please check here:
 
Beautiful, cheers
Given it a gander, everything seems to be in order on the A-board side of things (sorry for the shitty quality)
I'm really stumped, idk what the issue is. For what it's worth, trying Punisher results in a RAM_ERR message

Run the CPS-1 Diagnostic ROM on the multi and see if anything shows bad.

Make sure you’ve flicked the switch, as shown in the manual, to the right direction in relation to your C-Board type.

Reseat everything. Including the PAL and give sockets a clean.

It does sound like a RAM error, but I wonder why it’s only happening for 1.5 games.

Also. What is under the yellow tape?
 
Show a picture of the main side of the multi pcb.

I tried to get the things of potential interest, I'm sorry, I know it's awkward but scaling the pic down would make it basically useless
Gonna clean the sockets and reseat the stuff like what was suggested, fingers crossed

Cleaned the sockets and reseated the PAL chip, no dice
The test seems fine but maybe I'm missing something

Still poor quality photos. Try take something like this, where you can zoom in and see details.

Can you show a photo of the area closely that the Reset and QSound cables are connected to the multi?
 
Those connections do not look stable. Do you have the original wires included with the kit. Can you use a multimeter to ensure that connection is being made to the pins and that they’re not crossing over.
