Building a MK dynamo cab for someone and thinking of picking up a Mortal Kombat 2 board to put in it. The problem is that the board will only go into test mode.

Now on MK1 I know there is a DIP that will make it boot to test only. I asked the owner if he tried changing the DIP setting on the MK2, and he said he did with no effect.

Anyone know of another reason why the MK2 board would always boot to test mode?

Thanks!
 
If the test mode switched is in the "on" position on the cab. I had an MKII cab that had a toggle switch for test mode inside the cab on the coin door. Have him take a look by the coin door to see if there is a test switch that's on.
 
I wish it was that easy. No cabinet. I know he has a JAMMA test rig for his boards. He is just using the test rig.

Thanks for the suggestion.
 
When you say it's in test mode do you mean when the rom test or the menu? Has he tried coining it up and skipping the test mode? IDK, I have an MK board that will continuously run tests unless I coin it up. Once I coin it up it runs fine.

Ah, good point. I honestly don't know. I am only going by what he told me. Maybe it is not the test mode menu at all. I bet it is freezing on the initial ROM test screen. I would venture to guess that it has a bad chip(s).

Maybe I will see what he wants for it , if its cheap enough I just may get it to try and fix.
