    I put NVRAM into Monopoly about 18 months ago. Last night my son's 67 million #1 score got corrupted into 269,000. Anyone else experience corruption or loss of settings?

    Any type of RAM can fail.

    Or the socket could be failing (happens all the time).

    It is anypin NVRAM. Any one know exactly what type of memory this is and what its characteristics are?

    Wonder how much writing is going on to this memory and what effect that has...this pin is lightly used though.

    Anypin have lifetime warranty, although I know that won't get the high score back......

    The chip says Ramtron, looking at the spec sheet this thing is very robust....who knows, could be a software bug!

    I have Ramtron in all my games. Good stuff.

    Has it been 18 months since you turned it on?

    Quoted from exflexer:

    So. I put a Lithium backed 5101 with a 10 year life in a game about 15 years ago. Played it for years, put it in my mom's senior center for them to play for years, put it into storage for a few years. Then last month put it The Sanctum to play. Guess what? Worked like a charm.

    It is used at least weekly. The behaviour with the corrupt score also shows how the code handles it. Each higher score now comes ahead of it in the top score list but the artificially low score doesn't get kicked out, just pushed down along with the scores originally behind it. As a programmer I find that interesting!

    I've seen it numerous times with standard RAM, but not yet with NVRAM (although I'm sure I will at some point). RAM can get corrupted in other ways besides a bad RAM chip/socket. I would do a factory reset and see how it works after that. If it's in a socket, reseat the chip.

    I had an issue in monopoly with my nvram as well. In my case, I think it was related to my florescent light / starter going bad. The nvram sits very close to the light socket and I think the EM noise from the light going out currepted it for me. I have since I stalled an LED repacemnt bulb, and I haven't had any troubles since.

    Or could just have been a code bug.

    If Sega, someone (I think Crash) was able to point out 2 reproducible high score code bugs in the last couple of days.
