Hi all,

i bought a Captain Commando, it was working before the shipping. I got it yesterday and it has some Glitches issue, and also receiving this message error when entering a credit:

"Adress Error 001005DD", and sometines "Adress Error 0010065D"

I already tried this debugging:

  1. Cleaning the Jamma Port - No change
  2. Removing and installing all the ROMS - No change
  3. Removing and installing the C-Board - No change
  4. Replacing the A Board from my Street Fighter 2 WW - It was better but still has some glitches and same adress error
I added some pictures to show you the error.

Someone has an idea?

Do you happen to have another C board? You already took out all the e proms and re inserted them but make sure there aren’t any cracks in the chips. I had a issue with a board where there was a small chunk taken out of the corner on the C boards chip that was causing a lot of graphic problems. Also check for any damaged traces. I’m not sure what would be causing the error message, it might be a rom issue. Does your board look clean?
 
No i don't have a compatible C-Board, i have only a B17 Board and i need a B21.
I verified all the chips, no cracks or something else.

I will try to check the C Board like you said.

The Board is clean yes, and like i said before it was working before the shipping from the seller.

Thank you for your answer.
 
Tried today to clean the leg of the C-Board and the B-21 Chip - got the same issue.

I thought about the voltage on the board.

On my Supergun the 5V is:
  • 4.51 v on the Captain Commando
  • 4.57 v on the SF2 WW
Perhaps this is the issue?

I also tested my Tekken Tag Tournament, and there i have 5.2 V.

What do you think?
 
If it's an original Captain Commando, without any modifications to the C board, then it most certainly looks like the battery suicided, or is on its very last legs. My board had the exact same graphical glitches, got fixed by de-suiciding it.
 
No the battery was changed by the seller but i don't know when.
 
Finally i found the problem with the help of @roy.

We tested with his Supergun and his PSU everything works like a charm. Use my Supergun with his PSU same result.
With my PSU and my Spergun i'm getting the same glitches. ||

So the issue was the PSU, not enoug power perhaps i don't know ?(

Thanks all for your help and especially @roy :)
 
4.51V is incredibly low. I'm surprised that the board even booted at all.
For future reference, acceptable voltage for most chips you'll find on arcade boards is 5v +/- 5%.
Always check the voltage on your JAMMA edge and try to get it as close to 5V as possible. How close? Something between 4.9 and 5.1V is what I'd consider acceptable.
You must also remember that you have to check the voltage every time you change board types.

I’m confused. What battery is on a cps1? I know there is sometimes one on the C board, but I thought all that did was hold high scores. I know cps2 boards have batteries that need changed about every 3-5 years.

There are different types of CPS1 boards. Many are unprotected, some have encrypted code. The battery is a 2032 soldered to the board. The C board holds the key to decrypt the code.

Basically Capcom made SF2 WW and it got bootlegged to hell and back... so then they started encrypting their stuff. There's more details to it than that, but more or less they wanted to protect their IP. CPS2 and CPS3 they just continued the encryption.
