I have a pac board thats displaying the alt names on the intro screen yet the jumper is not jumped. Anyone ran across this one before?
The board otherwise plays great. Getting ready to take another poke at this board and figured I would ask here first. I do remember someone having this same problem a while back but a solution was never posted, if he ever found one. Havent been able to find that post but im sure its still here somewhere, hasnt been that long ago.
 
Could be someone modified the 6H or 6J (whichever it is) that you change to have different names and such. I did it once with that little program that is available. Can't remember the name of it.

Code:
1346      PORT_START("DSW1")
1365      PORT_DIPNAME( 0x80, 0x80, "Ghost Names" )
1366      PORT_DIPSETTING(    0x80, DEF_STR( Normal ) )
1367      PORT_DIPSETTING(    0x00, DEF_STR( Alternate ) )
 
Its definitly not a rom problem. I dont populate the rom sockets to do initial testing on a board. I plug a abc board into the side edge connector. I have also installed roms just to be sure anyways.
 
I made a little progress.
When I got this board row 8 was severely hacked from someone trying to track down an input problem that I found was a broken sip RM7. So I had to fix all the hacked up 367s at 8 D/E/F/H. I replaced them all and fixed a bunch of traces that had been pulled. What I found is that after swapping 8D with a new chip the problem went away but would occasionally return. After pulling 8D and reseating a few times the problems gone and I cant get reproduce it now. I think im still going to pull the socket off the board and recheck my work. Sounds like a trace might have been shorting under the socket.
I also need to take a closer look at the schematics to see exactly what the purpose of 8D is. I can pull that chip out and the game functions 100 percent, even the dips. Looking at the schematics it controls dips 3-6, difficulty and alt names pads. I will verify dips 3-6 are functioning without the chip, might be wrong on that.

No... they're controlled by a split pad that goes through the same buffer as the dips.

Yes, saw that and noted in the reply above. My bad.
Still not exactly sure what was causing the problem but its still working. I pulled the socket and everything looks good. Reinstalled socket and still working fine.

Well 4 of the dips will work at least. Pac will run 'fine' without all the DIPs you just can't set the # of pacman or points for bonus pac.

Thanks for the help guys, im going to let this one run a couple days and make sure the problem doesnt resurface. Im thinking maybe a piece of trash or solder may have been shorting something.

Yeah James, I wasnt able to retest but I doubt those dips were working with the chip out. When I tested I tried pause and freeplay, neither which are controlled with 8D. So....should have looked at the scat before posting that statement.
