**** that's harsh. Looking at the ketsui thread on shmups you could try adding a fresh battery and trying the NVRAM reset.

Code: Select all

The reason for this is that SW1 is used to reset the NVRAM and
the program code requires certain values to be present there.

To fix this behaviour do the following:
. Power up the PCB.
. Hit the test switch to activate Setup.
. Select "Restore Defaults".
. This requires that the battery is not dead. 
Don't know what else to suggest. Both yours and sourdiesels boards are missing batteries so it may be an idea.

Seriously hope you get it sorted. The last thing we want is these boards to start dropping like flies.

the thread is called "Ketsui PCB, glitches and EPROM revisions" it was started by rtw. I couldn't find it through the shmups forum, it was found in the Google cache hence I didn't link to it.

the cache is here though

...

edit, new URL.

Who knows. I only suggested it because rtw states that the NVRAM cannot be reset without a battery.

I'd be getting that battery of the galuda board and testing it out tbh... what's the worst that could happen ? :awe:

Perhaps Doutor will know an arcade repair guy in Japan who is used to the more up-to-date boards?

In any case, it's usually worth asking him as he'll have links to stuff that may help...

has anyone else's doj board died outside of the 2 mentioned here ..if not it has to be something to do with the battery ,whether or not replacing the battery now will make a difference who knows could be cps-ish ...how long was it since you powered it up ?was it any longer than normal?

kernow wrote:Contacted arcaders already via his service on ebay, he says PGM is probably too new to fix due to a lot of surface mount / custom components.

:(

:|
Just to clarify for anyone that's confused (ie me ;) ) - kernow was thinking that I was the guy on Ebay who goes under the name of arcader and/or redacra. That's not me, I use the Ebay name realflight. Perhaps I ought to ask the mods here to change my username to avoid any further confusion. :D

As for the board, never say never .......... might be something simple like a lifted surface mount pin, a dodgy RAM or, if unlucky, something more tricky like an (almost) irreplaceable faulty custom chip.

kernow wrote:Hmm, well I tried yosai's suggestion last night (replacing battery and resetting NVRAM with switch) and it did bugger all :(

I think its pretty safe to say these boards run fine without a battery, as mine did for months before it randomly took a ****. (except DOJ black label obviously)

:(
was worht a try if nothing :( have you got anything from shmups ?should try arcade systems as well ...

no-one on shmups has an idea really.

This is saddening, it just makes me want to sell the lot now.

We have a few French members round here don't we? Maybe one of them could have a snoop around on the French sites on your behalf...

I'm suspecting that there's at least a connection issue. If so I'm sure I can fix it as offered. :)
