So warzaid is a beast with
2 konami viper boards

2 omz-2d gun boards

1 konami gmc22-pwb board

The rtcs are ok
The network between the 2 vipers are ok
… and this
1E273DA5-4D33-4D4E-8333-5965FA9B1D6C.jpeg

…. And then it reboots.


Google returns ZERO hits on that error.

As you can see above, the previous owner, a friend, ordered and tried changing boards but still the same message.
The wiring looks ok, fuses are there and good, my next idea is to check all voltages,anyone has suggestions or ideas?

Thanks!
 
I know nothing of Warzaid other than I used to like it in the arcade but this era of PCBs is capacitor plague city, I would start by changing ALL of those mofos (and checking for messed up traces, etc).
 
where do the gunboards connect?
start with that and follow the traces.

btw, what happened to the cages?

The good news is I have the schematics.
The cages were just removed while we played with different U39, that's the picture I took before moving the game. They are back on now.

@dos you mean the gunboard right? They are the ones Sega uses so I could also try with a sega game to see if they work there. I'll also review @twistedsymphony lightgun page for hints.

Thanks guys. I WANT this game to work! :)
 
what do you mean "I have the schematics" ???
you mean of the VIPER board????

12.9v coming in the Konami gunboard.
12.03 in the 2 gunboards and 12.3 and 4.97 going to the guns so the 12v coming in is correctly regulated to 5v
10.9 and 5.02 for the Leds, which clearly appears to all be working:

All dips were set to off on the gun boards, moved them to ON for inverted and 10 leds (instead of 12)
Still no go with GUN BOARD BAD .... now I am wondering if its the gun board or the boards IN the gun. unplugging all guns made no differences.

on the vipers:
dip 1 ON = skip the CF card test which helps speed things up
Dip 4= mame says // Skip device check? wcombatu is playable when this is set ... but no change here.


for @dos : these vipers board ran warzaid fine in single cab mode (see https://www.arcade-projects.com/threads/the-obligatory-post-your-recent-purchases-thread.1970/post-307178) so I am not sure I want to start messing with the caps.

This is not going to be easy but I have a saying that says "the longer you search, the smaller the problem is" ...
 
I’d say that one of the gun boards could possibly be bad, looks like the older style OMC gun boards, could the modern ones be used here? Like the TC4, HOD4 OMC gun boards?
I have heard that the older style boards are less reliable than the “newer” SMD pcbs.

it's not these board, it's a SERIAL board and not an analog one. the OUT has 4 pins: TX,RX,GND,GND.
I have check continuity everywhere, everything is good.
I dumped the rom of the OMZ-2D CPU board... not sure if it's specific to warzaid or not, I don't see a lot of SERIAL gun games I could try the boards in...


Need a break... and some help :(
 
So running mame in debug solved one question I had:

where the hell did this "KBC:A" version came from?

Well running mame in -debug answered that:

bios.png


it's the bios!

if you choose B:

b.png


and even if you are running what is identified as ":B" version in mame, if you choose the :A version, it will say so here:

a.png



anyway ... it's news to me! so I guess I can go and see if both boards are on rev.A of the bios, and see if it is something that can be upgraded?!
 
thats interesting.
i put those bioses there! :D
they both came from u.k. origin machines from Electrocoin!

you can upgrade them, i think it's a 32pin PLCC rom soldered to the board.
i seem to remember the pain-in-the-ass of fitting a plcc smd socket. :D
 
Maybe the gun board doesn't refer to the OMZ gun board but instead that gmc22-pwb board. Check connections between the slave pcb (#2) and that gmc22 board.

Edit: There should be another pcb under that board named gyb09-pwb. If that pcb isn't present, then you can't do much. The wiring diagram can be a bit of a mess to the point it's easy to confuse things but to clarify, pcb 1 serial port = omz gun board; pcb 2 serial port = gyb09-pwb. May have more to say but I need to rethink some things regarding this game.

Edit: I forgot to mention again dip switch settings need to be set accordingly (on both viper and omz gun boards). Viper pcb 1 needs all dips off; Viper pcb 2 needs only dip 2 on. Omz board 1 needs dip 1 off and dip 2 on; Omz board 2 needs both dips off. There is way too much contents to keep track in the manual that some tiny things can be easy to miss.

Thanks for being here!

I have 2 of these gmc22-pcb+Gyb09-pwb combo board…and yes, after reading the manual very carefully, i saw it talks about the dips of the OMZ board and tried them that way, no change. There is a dip, and a jumper on that gyb09… know anything about them?

The viper dips are ok else the network check doesn’t go further and reboots.

I traced and made sure both of the serial link cables are ok. I am thinking perhaps i should listen to the serial link and see if i can see anything.
 
What about the boards IN the gun? Do gun needs to be plugged in for the game to boot?! ( i tried with and without, no change)

If you have tools to listen to the serial link, do so. I'm curious to know what happens if you plug the serial connector to the other gun board?

Also boards in the gun should not matter but because this is a complete unit, I'd keep them plugged in.

I kinda did that by swapping the right edge connectors… doesnt change anything :(

That...is not only not what I meant but the game would have failed to boot regardless if you swapped the right edge connectors (from the two viper boards). Swapping the right edge connectors meant you had the left pcb communicate with the I/O board and the right communicate with the gun board. I said "plug the serial connector to the other gun board" for a reason because this game is a bit picky on main to I/O board communications. The left viper board HAS to communicate with the gun board while the right HAS to communicate with the gyb09 board.

It could be possible you have the left viper board connected to the slave gun board hence why I suggested to plug the serial connector to the other gun board WHILE keeping both edge connectors in place.

Going to attach this simplified text diagram because it didn't translate well on this forum.

Ok i understand what you mean but it is physically hard to do it because of the wires lenght and connectors! They made it fool proof.

Ill give it a shot anyway. Thanks for that readme
