i have a mortal kombat 4 rev 1 and i took it out to dump the roms. when i connected back all the roms and switched it on on the mk4 cabinet, it said that rom u10 is bad. i have the cp of from the mk4 since i am restoring it, so i have no buttons.

i plugged the ocb on my mk2 cabinet.. when i switched it on, i was hering same strange noises, low low frequences sounds and there was no picture.

when i connected it back to the mk4 cabinet, nohing came up, not even the part where it checks the roms.

i tried another board on the mk2 cabinet and it worked. i do not know why the mk4 did not work on the mk2 cabinet. it seems that i have lost my revesion 1.0 of mk4 :(



can someone help me fix it?
 
Make sure you didn't plug the roms into the wrong slots or backwards. Also make sure you didn't bend any pins on the roms when you put them back in.
 
ahoy, yes, make sure the U shaped keyed ends of the roms are facing the same U shaped key ends of the sockets.

use deductive reasoning if you've installed roms in wrong locations eg. if 2 roms show up with errors, try switching them.

the sound roms are in one section, then graphics, and then at the bottom of the board there will be the two game roms. at least that's what I remember. :)

good luck
