Ultimate Mortal Kombat 3 Problem!
(1/1)
GuinnessGuy74:
Hello everybody! I am new to the forum and have a question about an Ultimate Mortal Kombat 3 board I have. It seems to have a resolution problem (i have been told it might not be a resolution problem, rather a pallette ram or address problem from a jamm+ forum)). I have enclosed a picture to show what I mean. The test shows NO bad roms!

My question is, does anyone know how I can fix this? If it is a replaceable rom chip, then where do I get replacement IC's?? Or must I reprogram a new chip (so in essance make my own?). If that is the case, how do I do that?

I am also not sure what rom chip it is, since the manual I have does not list which are which. It lists then simply as EPROM Assy (16 are image, 6 are program, and 4 are music/speech) and 3 FPGA Assy. How do I know which ones are faulty?

As you can tell, I am very new to the arcade machine world, so bear with me. I am pretty good with electronics but have no EEPROM experience.

Thanks for all the help, I really appreciate it!

It's never been fully fixed. Tough breaks. Do some searches on it, and you find this out very quickly.

It reads like his is a real pcb, not a mame problem.

I'm not qualified to help you with a pcb repair/reprogram but I think you might want to make a similar post over at www.klov.com they have a repair section on there message board.Hope this helps.
