@lydz - i picked up two of these in the hope of fixing my Magic Sword and Final Fight boards which I believe are failing due to the C board.

I can't get these to work. Am I doing something wrong?

According to your first post for Magic Sword (B13 on the C board), the DIP switch should be set as 54321 = 11000. I assume 678 dips don't matter to functionality? Regardless, when I try the C board with these DIP settings I get even worse graphical output than the stock C board.

Same issue with Final Fight. It goes from partially screwy graphics to total garbled graphics when I use your C board. See attached for example, the sprites are all just blocks with lines in them.

B13 = 00111
 
@xodaraP - I don't know how I missed this but took a closer look and my Magic Sword C board had a broken trace. Patched it and BOOM I have a working PCB now. Graphical issues went away.

@lydz my PCB is definitely working now with the stock C board but I still get those weird blocked pixel graphics when I use your DIY board. I still need it because my other PCB has a failed C board that shows no obvious physical abuse.

See the attached pic. I have the settings as 00111 and I can't get it to behave like a B13. What am I doing wrong?

I still can't figure out how to make these work. @lydz would appreciate if you can confirm my screenshot above. Is that correct? Cuz it doesn't produce anything but garbled graphics for B13.
 
motherboard is fine. It works if I use the original C board. I actually fixed the original C board by repairing a broken trace.

Are my dip switches correct in the pic? I actually bought 2 boards off ya and neither works with those settings. So I'm hoping I have it configured wrong.

@lydz i took one more crack at this trying with multiple settings for what I assume is B13 could potentially be starting from right and left. Can you look at the pic I posted 3 messages prior and tell me exactly what I need to set the DIP switches to please. Not sure at this point what I can do further to get these to work..

Has anyone else picked one of these up and got a B13 (or B4) going?
 
Hi all,

How many users bought from this C board? Whoever bought it will tell you that it really works. I bought one, it didn't work. I paid for another shipment, got another c-board, arrived today, I tested it doesn't work. A friend also bought, does not work. Lydz doesn't answer. This is correct?

I bought one and I assume it works fine. I say I assume because I only tested it with my Street Fighter 2 World Warrior (B-17). Worked with no problem.
 
I tried original Final Fight, Magic Sword, Street Fighter 2 World Warrior, Three Wonders. None work on either, no matter how I set the switches.

:/ — paging @lydz

Did any of y’all try to return it or get a refund?
I wrote to taobao support for the first defective product. You will then be offered to refund the price (postage will not be refunded) or resend the product. I asked to be sent again because I need it. I asked the seller to send me a test video of exactly the product they will be sending me during operation. I got a video that shows it in action but I can’t say 100% that I got the same. When I arrived I took a video from the unpacking to the testing where it can be seen that the new card is not working either.
