None that I know of, you rarely need them. I doubt even shaking the board about would have cause it, the areas of rot are minute and must weigh fractions of a 1000th of a mg.

Basically we burnt a lot of time checking and rechecking things, replaced one of the 74ls373 chips in the hope of proving a point, but it didn't improve anything and its activity looked identical to that of its peer.
A few Brits on there, me included, but is probably the best site I have found for an arcade community. The moment they are approved we approve submissions twice a day. It seems the stuck address lines are permanently tied low anyway by the board - this board has tiny tracks and most are under the chip itself. If you are into arcade repairs then I reckon now is the time to get yerself a logic probe, you can get them for about 5 quid. One section of the board nowhere near the sprite area has black dots on the tracks under the laquer. I would take the risk and do it but I am not that skilled like twistedsymphony By the way do you guys also have that sound noise at the silent opening sequence when the intro shows the jet go up? I can help you out with how to use the probe, and also where to start based on your fault.
I had hoped I could get the chip off the board to test it externally but I could not clear any of legs and ended up cutting it off. I needed to temporarily join the mask rom pin to the 373 to prove the fault, and I keep meaning and forgetting to make a lead with a probe at each end. There are three stages, Practice, Novice and Expert. Chances are, that since you are here, you must have either played or are going to play this game. Most of the sprites were a mess even tho the backgrounds were perfect. One track clearly has just oxidised through, nothing could be done to stop it.

I'm getting into more advanced board repair now, it seems. Try to understand that this is a electronic item, the boards depart from my store 100% working but i can not guarantee that arrives full working. One of the address lines was no longer connected, break is probably underneath a chip. Took me about 30 seconds to spot something nasty, pin 36 was not well on one mask rom, most of the time it was healthy looking, regular pulses, but when the crap was on the screen it had a lot of noise on it, spikes that didn't get anywhere near half way between logic 0 and 1.

Somewhere there is a rotten track, it might be a one off, or there might be others that are not in the best health. Once you know if the sprite system is actually active then you can work out where to go next. Oh you mean the key to what is ringed and labelled, no sorry, it's not my photo and there was no key. When the two pins were temporarily joined all the faults vanished, everything was perfect. Also there may be some other differences related to these address lines that aren't immediately apparent. Game has been running like a charm for the past hour and hasnt missed a beat. The surface mount custom chip in the Red ring 8 is the sprite controller chip - if this is damaged the board is pretty much scrap unless you can find someone locally to replace that chip.

Like Womble, I could not see where the break was either. Practice features one level only. For additional information, see the Global Shipping Program An item that has been used previously. I did wonder if I had damaged the track while desoldering the chip but I hadn't. No approved descriptions in database.

What was not good was that all the tracks coming out of that section went straight into the fat custom chip Red 8. Will post more when I am at a real keyboard and not on a tiny phone screen. What are the chances the same exact problem with track rot could occur? It would be really great if you could please submit a description for this title as that makes emuparadise. As there are some parts of the attract mode cycle which had no problems, clearly it is possible that any issue visible on the board could show up when the board is throwing sprites around.

I don't recall any noise at all on the intro of it taking off from the woods.
