Anyone with a working Konami Police 911/2 board ?

I have a Police 911/2, but I don't know anything about that chip or how to get its contents. Do you have any details about it... is the chip socketed, and are there any MAME dumps of Police 911/2?

Hi, the Police 911/2 is one of the few games for which the NVRAM is NOT currently dumped - only the data of the corresponding CompactFlash card so any help is MUCH appreciated and might help others that will have the same problem in the near future (the battery normally lasts ~8 yrs). The Chip (if you open the Viper case) is located directly below the KONAMI logo written in white paint and looks like a 4x1cm brick. Mine is already socketed but I hear from others that their Viper board has this chip soldered to the board. Could you check yours ? It has the String "M48T58Y-70PC1" written on it and is a TimeKeeper NVRAM with a battery in it. I am able to dump and re-write the data from/to another chip. but as mine has already a dead battery - I am to late here :)
 
Ah... I'm familiar w/ the timekeeper and zeropower chips. I just popped my case open, and unfortunately mine's not socketed :/ . What's the point of this chip, and why/how does it cripple the game? Is it meant as a security chip like a suicide battery kinda thing (pretty bad one if it's an off-the-shelf R/W NVRAM), or why can't it rebuild the NVRAM when a new chip is put in? Is it just making sure it's a valid time, and if so, couldn't you program the time on a new one and pop it in?

Also, my cab was upgraded from Police 911 to Police 911 2, so doesn't that mean you could use the NVRAM of Police 911, then "upgrade" to Police 911 2? The manual shows that the PCB is reused, and all you do is swap the CF card and the security plug.

An interesting point, the upgrade kit. I just used a copy of the P911 NVRAM from Mame but that didn't work. Each CF card has a corresponding amount of NVRAM data (which is stored in the TimeKeeper chip) that is different from game to game. And the NVRAM will not be updated/reset/re-initialized once you insert another game which leads to -> get a working P911/2, take the chip out, reading its data and write it to a fresh TimeKeeper chip. I tried all combinations and neither worked. I just took the opportunity to ask benson.com if they are willing to offer the NVRAM data for Police 911/2. At least this is an original game I payed good money for and if Konami uses such a "special" design that run's out all 8-9 years when the battery goes flat I would appreciate that effort. I don't have an upgrade manual at hand, what did you mean with "the security plug" ?

Hes talking about the rtc "security plug" This is what is needed for the conversion from police 911 to police 911/2. I think I may have the conversion manual. Ill look for it

That would be great - I think that could also lead to resurrected p9112 :)
btw, where did you add the VAPS link that's visible in your post ? I'd like to add mine too...
 
the rtc must be connected at all times to boot the new cf to the old pcb. Strange thing is that I have a japanese version that does not require a rtc to work with the original police 911. So it seems that theres different versions of the board out there.

ok, seems that we both have the same 911/2 as we don't need the plug.
 
Well no...my police 911/2 needs the rtc plug as its the conversion from the original. I have an original police 911 thats a Japanese version that doesnt need the rtc plug. I also have another original police 911 that needs the rtc plug. Not sure why this works like this

ok, 'fascinating' as Mr. Spock would say :)
So seems mine is of type original police 911/2 japanese that didn't need the plug. if it is a conversion - I don't know - I received it already like this, with no plug and working all the way. There is the question if there DOES exist a Version of Police 911/2 at least that is original and did NEVER needed a conversion.
 
I thought that was kinda interesting... I had seen pics around where there were no security keys, but mine has one. Then looking at the manual, it says to remove old CF (store in safe place), insert new CF, insert security key... nothing about "remove old security key".

Also, when you write data to the Timekeeper, are you setting the time? IIRC you have to do a special operation to set the clock, and not just write it as you were writing the rest of memory.

There are versions out there that do not need the rtc to work..No idea which ones or why they dont need them. There is a true police 911/2 board that was produced along with the upgrade kit. Id imagine the kit was more common and needed the rtc and the true board did not. Possibly the code was already programmed in your chip that went bad?

I also have a blade of honor, world combat and warzaid that are all konami viper but do not need the rtc to work. So the code must be programmed somewhere inside the pcb instead of the removable rtc.

No problem - I can take either set of mame, write the corresponding NVRAM of the game to the TimeKeeper Chip, use chdman and write the image to the CF Card and run the game - that alway works. In the case of Police 911/2 there's only the CF card image available (marked 'no dump' for the NVRAM in MAWS). There seems to have been complete code in my NVRAM that worked without security key - and now it's gone :-(
 
Hey t,
I've been looking at this for awhile..try this. I believe that the nvram data is that same for world combat And police 911/2 ..same name and valued. World combats has been dumbed. Try to use that in place of police 911/2 that is undumped. Thinking out load that the values are the same it could work. Trying to remember I believe its nvram39 or similar that both games share. I'd give that a try.

Its either the same or they labeled them both nvram39. Or that because theres no dump for them..duno

I tried all available nvram images out of mame, neither worked. I dunno why there's a dump of the CF card but no nvram. maybe they just got a bunch of CF cards and not the complete boards and dumped what's available which is already valuable. but the nvram of P9112 seems still to be missing.
