Tech Tip #12 - Faulty ROMs - Be Afraid!!
This is a not-so-obvious fact that everyone should be aware of......and focus is mainly on OLD Eproms, not current (2000 onwards)
Erasable Eproms (the Roms with glass windows on them) can only hold their data (guaranteed) for around 10years, although some may hold for 15-20, it all depends how much they're been used, and also how often they've been re-programmed over the years....
If you're wondering why a pin isn't booting, gameplay is random, or your sound roms are suffering no speech, gaps or missing effects, then these can all be caused by what we call "flakey roms"
It certainly pays to download the rom files from various sites, and having a backup when things go 'flakey' ;-)
One of the first things i did at my work when receiving new equipment was to pop the lid off and copy the Eprom to a file, knowing that in 10years time, there was going to be trouble and we had a plan.B to get by....

Common sense is sometime so common that everyone ignores it ;-)

Interesting topic ^^^
I just got new Eproms for my Party Zone and the Getaway. What a difference with Party Zone, I changed it from an L1 to an L3, the game plays different and better than before. The old L1 chip was the same as you spoke of with the glass window. So the factory Eprom must have been replaced at one time.

You're improvement might be a software version upgrade? as opposed to having a really dodgy rom?

This is where I got my Eproms from http://cgi.ebay.com/Party-Zone-Pinball-chip-upgrade-L-3-/220756986857?pt=LH_DefaultDomain_2&hash=item3366244be9
He does Eproms for most of the Bally and Williams games. He is in Collingwood Canada not Melbourne, "lol"

Thanx guys for the positive support...
I know most of tips may seem obvious or very simple, but for newbies and non-tech users it may be very helpful info....
I just keep typing them up as i'm doing things myself, and feel it might be handy to share....

Good tips Marty, I have had corrupt eproms twice on Williams Pins. Really strange faults, one was on Fish Tales and the reel would not operate, was Ok in test mode but noting during normal play, turned out to be the eprom.
Keep the Tips coming Marty, good reading ^^^
