Raiden DX - battery?

Post by **system11** » Wed Aug 02, 2006 4:18 pm

Looking at my Raiden DX board, there's a 2 pin connector for a battery, and a battery sized+shaped component position right next to it, with holes for a battery clip or plastic tie.

Does anyone have a battery on theirs? If so, could you post or link to a close up picture of the battery and fitting?

For Bloodflowers,

I've got a USA Bios Seibu Kaihatsu/Fabtek version of Raiden DX PCB and it doesn't have the backup battery installed whatsoever. However, my Raiden II PCB does have a backup battery installed. It just needs to be taken out and replaced with a new one for high score posterity. ^_~

My Raiden DX board doesn't have a battery on it either (in fact, it has a "warranty void if removed" sticker where the battery would normally be.) Here's a picture of a Raiden DX board which has a battery installed though:

My board is an Asian (Metrotainment) version.

Here is a picture of the battery installed:

Note that there are extra components mounted when the battery is mounted. I have now removed the battery.

Mine looks like the Raiden 2 picture above - black 2 pin clip, extra diode. I guess it had a battery once, and someone has pulled it off.

I just tried my Raiden II with a new battery.

However it did not save any high scores. If you trace the + you will see it goes underneath one of the larger SMD chips instead of towards the RAM.

Anyone care to shed any light on this ?

rtw, you're timing is uncanny. I too just discovered the same. Rastan78 ordered a Raiden DX board in the group order, original battery dead. I attached a fully charged battery and no score saving either.

In the manual it says 'do not remove battery as some part of circuits are using them'..or something like that. I guess it was used by Seibu to help with diagnostics (clock?).

Interesting timing

, what manual are you referring to ? Do you have a copy/scan of it ?

For oxtsu,

And would the above listed statement apply to a USA Bios Fabtek Raiden II PCB as well? (My Raiden II PCB does have a back-up battery.)

But high scores aren't saved upon powering down for the night on my Raiden II PCB.

So why is it that I have seen such Raiden II PCBs in the past that do save high scores and others, don't?

The usual two-page (like a big sheet of paper folded in half) thingy that tells the JAMMA pinout and what not. No scan, sorry.

No pic either. I meant to, but was short of time and not a priority of course (group order).

Someone else must have this one? If I recall, sheep had it up on his manuals download page way back when.

Maybe you mean this:

I don't read/speak Japanese but I'm guessing the information might be on the last page ?

Yes, it is #3 on the back page there. In the JPN Raiden DX manual they included an English translation below each one though.

For oxtsu,

Could you provide English translation of the last page of Raiden II PCB manual for Section #3 paragraph?

So if battery is replaced, then saving of high scores won't happen then (on a Raiden II PCB)?

Yeah, that's it.

Did anything ever come of this? I'd love to get my PCB saving scores, assuming that's what the battery is supposed to be for?

For cools,

If your Raiden II or Raiden DX PCB came with a backup battery installed at the factory, they did at one time, save high scores upon powering down for the day. However, if the original battery died or if it was removed and replaced with a new battery, then saving of high scores on that particular PCB was lost forever.

Sure, I recall seeing some Raiden II PCBs that did save high scores and others, that did not save high scores whatsoever back in the mid 1990s. ^_~

My Raiden 2 board doesn't save scores either. No biggie, but it's kind of wierd that putting a new battery in does nothing. A hi score suicide battery of some sorts? I have a couple of old Atari dedicated cabs that still save high scores to nvram with no issues after 25+ years. Shame on you Seibu

Even the ol' Atari Games produced Klax PCB saves game settings + high scores without the need for a backup battery and that hails back from February of 1990 when it was first released in the USA arcades. ^_~

To quote the manual:

"The circuits have been partly battery backed-up. Please desist from
carrying out conductivity inspections with such tools as circuit testers as
these can cause short circuits. And never remove the batteries."

IIRC Zero Team (which runs on the same hardware) used some kind
of battery backed protection mechanism. If the battery died the game
would die as well.

So it looks like the batteries are remnants of a protection that was
never implemented.

So could you restore the original NVRAM to make the game save battery work again, similar to DOJ BL NVRAM restore? Or is it not worth the trouble/expense?

That'd be cool if such a Raiden II PCB with a high score saving battery could be restored, rtw. ^_~

I think there is a misunderstanding here.

The PCB never saved hi-scores. The battery stored encryption keys like
in CPS2.

So that explains the reasoning why Seibu Kaihatsu wanted it's Raiden II/Raiden DX PCBs to be encrypted and safe from bootleggers. Makes logical sense now. ^_~

No backup battery on my Raiden DX PCB...

Re: Raiden DX - battery?

Would new back-up battery installed in Raiden II PCB work?
