DDP3 Black Label... Clarification

SuperPang · Post by **SuperPang** » Fri Aug 17, 2007 11:10 am

Scratch one more DOJBL. Mines dead as a dodo.

If anyone can arrange a return to Cave I'll have your babies.

How many arcades in Tokyo have a BL? They'll start taking notice when Hey call.

Never charge. The battery is not designed to be charged by any
other electrical source[/quote

Oops ! I did no pay attention to this but actually it has worked with no problems for 1 year, I'll have to plan another swap fast if I don't want trouble, thanks for advertise

The CPS3 is sensitive
to voltage fluctuations and this might trigger the deletion of the NVRAM.

Sure it is, but due to the hardware conception it's the easiest way to swap the battery on these carts. I've ben lucky, I have changed the battery on two games and they are still alive

Sorry to hear that

Hey probably keep their machines powered on a lot more than we do.
This trickle charges the battery avoiding this issue altogether.

GaijinPunch asked Mak, maybe he could ask Fujita as well. I wanted to buy
a DOJBL from them a while back but they couldn't deliver because it had
"battery" problems.

I would ask Fujita. Tops also says in plain Japanese on their front page that they "fix PCBs" so I'm sure this is within their realm. I might be able to whip up something as a last resort. I don't like like handling $1000 PCBs if I don't have to.

Cave phone : 03-5366-3310

I could help organize a group send, though it would be easier for GP I think.

i had a rather lengthly email conversion with TOPS and they won't accept a board that they didn't sell. i tried to be rather clear on the situation and they confirmed it would have to be sent to cave but they would not accept a board that wasn't sold to me from them for repair.

this is rather disappointing, seeing that they were rather good with my mushihimesama to get sent in for fixing. that was however bought from TOPS, and they sent it to Cave prior to shipping it off to the USA.

I managed to perform the dry run on my normal Dai-Ou-Jou today with succes

First I entered the setup menu and changed all parameters
so that I could verify that the NVRAM was not cleared.

Then I laid out my tools:

. Soldering iron
. Solder
. Desoldering pump
. Desoldering wick
. Wire cutters
. A freshly charged VARTA battery

I powered up the PCB and laid it gently on a chair. Then I
wiggled the JAMMA connector to verify a good connection.

Then I started the procedure:

. Snip of the existing battery
. Using the soldering iron and tweezers I removed the remaining battery legs.
. Cleaned away as much solder as I could using the solder wick.
. At this point I turned the PCB to vertical position.
. Then I started heating the battery pad from the solder side while using the desoldering pump on the other side.
. After a few tries I managed to remove all the solder and open the holes.
. Then I put the new battery in making sure that the polarity was correct.
. After that all I had to do was solder the new battery in place.

Note:
Make sure that the tip of your soldering iron is not connected to earth!

Next up is the Black Label

Once again, excellent job rtw. I can't wait to see what happens with the BL board! I have a feeling it will be a success.

Post by **Dave_K.** » Sat Aug 18, 2007 10:06 pm

Cool, this was like open heart surgery replacing the battery while the PCB is powered on!

Radiant · Post by **Radiant** » Sat Aug 18, 2007 10:32 pm

Maybe it sounds stupid, but i would try to replace the battery, and look if the PCB will work again...
I have the demo crash @ ketsui if i don't play it for a long time, when i power it on on the next day it's working fine...

the question is when i switch on the PCB the battery isn't needed, but why does my PCB crash?
and on the next day (when the battery is full) i don't get the crash?

maybe u have a spare CPS2/3 Battery at home, and u can use it for this experiment

Good work chief

Got great hopes for your BL too.

parodius · Post by **parodius** » Sun Aug 19, 2007 6:57 am

Just tested it, and my BL is still alive, even after not having been powered on for the last 5 months.
I'll let if run for ~24h just to be safe.

The reason for your crash is that you have the original version of Ketsui
and not the fixed one. It will exhibit this behaviour. If you don't want to
upgrade do the following:

. Power on
. Enter setup
. Reset all settings to default.
. Never ever touch the brown button.

I would get the fixed version though

Radiant · Post by **Radiant** » Sun Aug 19, 2007 2:49 pm

Yes i know..maybe i should get the fixed Ketsui rom...
but i thought if someone has a battery laying around it's woth a try....

i think it just needs a rom change , thats why cave released a fixed version

Radiant · Post by **Radiant** » Sun Aug 19, 2007 3:35 pm

ok sorry for misunderstanding
Someone of the dead BL owners should try to replace the battery
my ketsui is fine (the demo crash is no prob)

Than you TWE, I did the Black Label this evening and it was a 100%
success. Only difference was a bit more sweat

So a live swap is the way to go.

And you have to use the Varta battery. It's high quality!
I got mine from Mouser.com, stock number is: 672-55608303012

rtw, so how long will the new Varta battery last without the PCB being powered up? Any estimates?

No idea really, only way to know would be to measure the current drain
from the battery while the board is not powered. Which I did not do...

excellent work , maybe you could offer a battery swap service for a fee to the unfortunates that have a dead BL , wouldnt fancy doing it myself tho

I think you misunderstand, the battery swap has to be done live on
a working BL. If it's dead changing the battery will not help.

Battlesmurf · Post by **Battlesmurf** » Sun Aug 19, 2007 8:10 pm

lol..that is a shame, too. I am considering purchasing a deal BL- but I'd hate to spend that money on something like that and never be able to use it. I hope this is along the lines of CPS/2 stuffs in the fact that it will eventually be able to be 'fixed'.

oh my mistake , thought there was a fix then

AST-DGN's Black Label gives the rom error screen......

First of all congrats to rtw for his great efforts and results. Btw I've read the thread so quickly that I didn't get the point: if this rom error message pops out, does it mean that the pcb is dead and gone? No way to bring it back to work again?

GaijinPunch · Post by **GaijinPunch** » Sun Sep 02, 2007 9:57 am

Yes. The good news is that I will buy dead boards for a few hundred bucks.

Hi also on my BL has appeared written ROM ERROR A this point that must make? E' by now late in order to restore the BL?

I see from the arguments that the battery goes changed, this first or after that the game stops to work?

Seen the problmei that the BL has had because of the battery and therefore must change it also to the other games, DDP DOJ, ESPGALUDA, KETSUI? These games in future could evere the same problem because of the battery?

Thanks

I think I will have to put this in the first post

If you get a ROM ERROR with your Black label it is dead and can ONLY
be fixed by Cave/AMI.

If you do not get a ROM ERROR, it would be wise to replace the
battery as I have outlined above.

The Black Label is the only one which uses a suicide battery.

Raiden Fighters 2 · Post by **Raiden Fighters 2** » Sun Sep 02, 2007 11:50 am

Thanks of the information, inasmuch as there are many BL that are died someone to tried to ask CAVE or to AMI if they can repair the BL damages to you?

What a great new ! I'm glad for your BL, damn this game needs to be preserved, this is manic essence. Congratulation for your job man

Besides mine is not back home yet, Now we are in september I have great hopes
