I just ordered another board because of the u99 failure. In the meantime I was wondering what other boards these chips appear on? Any insight would be appreciated.
thanks,

have you tried resocketing it and or making sure it's fully socketed yet? that tends to be the issue with these.

yup. I took it out, blew on it (hey, it works on nintendo carts. lol), reseated it. Checked all my voltages at the baord. The game still plays fine other than the slightly annoying graphic glitches. I'm just wondering if there's any way to get this board back to 100% or if it's now a parts board. I suppose I could use the test patterns on my bench.
edit: all four corner pins have a bubble on them. I assume those are normal and act as a depth control.

sounds like what mecha's was doing and his just wasn't fully socketed. the test patterns are definitely valuable but yea i hear ya on trying to fix it as it is a great game.

Blowing it out wasn't a bad idea at all, i hit mine with compressed canned air anytime i pull a chip (hopefully removing anything that could have been under).

i suppose another possibility is a cracked socket (i've heard of that before as well).

I didn't see anything obvious when I had the chip out but I suppose I'll ohm out all the pins on the socket to double check when I get time later.

times like these I'd just give it a bath :D

I mean, I use the simple green and a toothbrush on everything now.. I don't think a socket failure is very common on those, usually it's just a chip that's barely not in the socket all the way that causes it. you'll know when it makes a *crack* sound if it's in all the way or not.

I had an MK1 board that would do what yours was doing, someone scraped the shit out of the traces on the back, and I think some of them were crossed, so I picked at the parts between the traces to eliminate that and I reckon I got that board to work fine after that.

I don't know about the Y-units, but the T-unit boards generate a false positive if the game roms have corrosion on them, case in point my MK2 used to give me UE13 errors when I saw the game roms had shit on them.

I would pull all the socketed chips out and inspect them for corrosion first, software can do weird things.

and Broods, mine was one of those series resistors was cracked in half causing my problems lol

hmm i thought you had a graphical glitch too caused by your u99 not being fully socketed... oh well you know i have a terrible memory lol.

lay off the kush. ;)

I don't know, I don't remember it throwing any errors at all, just made the text blocky. and of course the "grey screen" thing that well.. you know about that.
