Mortal Kombat CMOS Error

[whoamonga]

Hi,

I'm very new to the game of board repair, and I have an MK 1 board that reports a CMOS error at U49.  I located U49 on the board, then in the manual.  The manual give a little bit of information that doesn't say much to me, but maybe you guys?

Part Number: 5700-10176-00    Designator: U49    Description: 28 pin socket

Am I correct in assuming that this ISN'T a ROM chip.  Could this board be repaired simply by replacing this chip with a new identical chip from somewhere?

The MK Title screen tries to display, but then it reverts back to test mode and tells me to hit any button to continue, and I'm caught in a loop...

Any help would be awesome!  Much Thanks!

Is your battery good?

[Malenko]

change the dipswitches so it runs from dip settings instead of CMOS; or replace the battery . they have the batteries at staples just take the old one with ya

[whoamonga]

I'll replace the battery. 

When changing the dip switch settings, it still came up with the CMOS error.  I had it switched to coinage...but no dice.

but i'll get a new battery and see what happens from there!  thanks!

[Malenko]

coinage is CMOS

basically bottom ro dipswitch you want you want dip 1 off and dip 8 off (dip determines, and test off) if you want free play dips 2,3, and 4 should be on.

heres how I have mine set up:

dipswitch row 1, all off
dipswitch row 2, off, on,on,on,off,off,off,off

blood,violence,low blow all on. dip determines, free play, USA, 1 coin chute, test off

I used the dip switch settings you suggested, but still the same problem.  I haven't replaced the battery yet so maybe that will fix it.

It still tells me it's unable to load factory settings, and U49 is a bad chip... so hopefully battery.

I'll keep posted!

[Malenko]

what version MK board do you have?  I have a Version 2.0 and I have no U49 rom  . Please note , I removed my battery and the game still started up so I dont think simply replacing the CMOS battery is going to fix your problem.


if your switches are set like mine , you should get this screen: (dipswitch coinage)



and not this one: (cmos coinage)


this is the dip switch screen in the test menu:



this is the rom check screen I dont have a U49 at all:



 you might have a 4.0 or 5.0 which is a Wolf based MK board, not the same as mine. Forgive the crappy pix, my camera might suck but its a pretty good cell phone :p

[whoamonga]

It's revision 3.0.

Here's with dipswitch coinage.


Here's with CMOS coinage


And test mode...


I don't think U49 is a ROM... it's just some 28 socket chip on the board.  It's a little larger than some of the others, but when I looked it up in the manual, it had no description of its function other than "28 socket chip".  Just for grins, I might try replacing that battery and the chip, but I'm not sure if an exact replacement chip would work... maybe there's something specific to MK on that chip?  But that would make it a ROM, PROM, or EPROM right?

Please pardon my lack of knowledge on the subject.  I am trying to learn though...

Either way, it fails to restore factory settings, unlike yours.

If it's the chip I'm thinking of (I don't have my MK board in front of me at the moment) it may have just gone belly-up.  We had a Terminator 2 that died, and I ended up pulling a similar chip from a MK board to fix it.

[channelmaniac]

What's the part # on the chip? I may have one.

Also, double check the bottom of the board for gouged or otherwise damaged traces. Those MK boards have fragile traces.

[northerngames]

kinda funny that the low blow is an option to turn on/off

[whoamonga]

the part # is
LH5160-10L
Sharp Japan
9207 7 DC

traces looked okay, but yeah, the board sounds like i'm handling cracked glass when I touch it.

And that one dip switch does seem a bit extreme to toggle just one move... especially for a game already pushing the envelope!

[northerngames]

I wish they would make another one with the charectors made like they were in the original were they are actual video recorded actors instead of pc made charectors.

12+ years later they should be able to make them look pure lifelike now.

the street fighter movie version was lame but another MK done like the origianal but with todays tech would be cool.

your math sucks. 2008-1992 = 16 years
it would be awesome if they made a new MKII ish game with digitally captured actors Im not a big fan of the 3D MKs and I think the MK vs DC game is gonna blow goats

[northerngames]

yeah the 3d MK's I dont care for and liked MK 1&2 the best

I just put 12+ years becuase I forgot the actual date it came out but knew it has been some time now.

Your chip went out today via USPS First Class. You should have it by Saturday.

Hey man, REALLY appreciate that chip.  I'm hoping to get a 28-pin socket for it this weekend.  Are all 28-pin sockets the same size?  Or are there gap measurements to know also, like on a molex connector or something?

as far as 3d Mks....

Man that's a whole bad can of worms...My relationship with MK got a little shaky when they included the RUN button and dial-in combos (CHEESY)!  But with the 3d move in MK4... I mean, I get that they were trying to get hip with new technology, but they didn't have to go 3d to do it!  Street Fighter didn't have to go 3d to stay alive (nobody mention EX!).  But it does seem that MK is finally taking some successful ideas from the SF playbook by versus-ing another realm.  But with a still-3d game, I've got 0 hope MK vs DC will be a good game.

And with the lack of success of MK4, you'd figure they'd figure out that 3d wasn't going to work for them... Instead, they try 3d, with some other add-on...they come out with 3d Deadly Alliance...now they fight with weapons!, 3d Deception...crappy konquest mode!, 3d Armageddon... more characters to suck with!... BLAH!  I was such a huge fan of MK that it wasn't healthy, but with the 3d games in particular, they helped cure me of that.

[Malenko]

then we feel exactly the same way. I really hated 3 but UMK3 grew on me a bit, I liked Trilogy because it brought back Raiden even if it was an MKII hack :p

heck I used to be knee deep in programming an MKII clone using the UFGE engine (an engine designed by me and a friend) I still have a majority of the files......somewhere

I thought Mortal Kombat: Shaolin Monks was great but needed a few more actual MK charector's instead of fill in creatures.

I would be intrested in a part 2 if they made one.

[whoamonga]

I'm really hoping that you pick that project back up...


the mk konquest mode could've been great!  like shaolin monks...it had potential.  but konquest mode especially, seemed only 1/2 finished...

Sorry for the delay, was on a 7 day road trip to Canada with my son. 3115.7 miles in 7 days. Whew!

When buying sockets there are many types to choose from.

28 Pin sockets bring a little more confusion too as there are different widths.

Standard is .600 wide, which is what you need. High speed SRAM (cache RAM, etc...) comes in .300" wide.

There are single wipe, double wipe, machine pin, wire wrap, ZIF (zero insertion force), and more available. You REALLY want double wipe as it's a better connection. Single wipe and machine pin will work OK too but the machine pin ones can be tough to get chips into at times since the pins on the chip will have to line up perfectly.

Stay away from the ZIF sockets as they are big and take up lots of board space and the wire wrap sockets which have long legs that are thick, square, and may not fit in the holes on some boards.
