    Default NES Pool of Radiance - battery or dead cart?

    I've got Pool of Radiance for the NES with odd behavior. It loads up fine, I can make a character, but when I go to the Character select screen or the Order screen, there is just one 'name' and it is nonsense characters. Not even letters, really, just odd squiggles and such. It is also stuck/frozen on that screen and I have to reset.

    Is the cart dead? Just the battery?

    I've cleaned it. Opening and polishing the contacts. I'm confident that's not the problem, so I guess it is something else. I'm also doubtful that it is the battery, mostly was just hoping.

    About the only other thing I'm capable of is replacing the caps. Worth trying?

    Ack, that sucks.
    I have no clue why it would glitch like that. Even if the battery is dead it shouldnt do that.

    I doubt that the problem would be the caps, but Im not a expert..

    When you are polishing the contacts, are they still gold colored afterwards or silver colored

    If it's a problem with the board you could swap the ROM chips with a compatible donor board, if the ROM chips are bad then the game isn't really repairable.

    If you can, maybe check the board for continuity between the chips and throughout the traces.

    Definitely still gold in this case. There are some carts that are harder to tell, though, and just seem more silver in the first place. I'm not scrubbing away at them or anything. It just takes a titch of polish and some gentle rubbing and the black crud comes right off.

    I'll poke around at it sometime. Thanks!

    Try replacing the battery, it's possible that the coin cell got weak enough that the stored ram data was corrupted. I recall a similar issue with a copy of Super Metroid:

    Its worth a shot, however not too long ago I tested 2 copies of Pool of Radiance, in one the battery was dead. It started up just fine.

    It's possible that the battery has just enough charge that it's floating some corrupted bits in part of the ram- certainly couldn't hurt to try loading the game with the battery completely removed to see what comes of it. It's a less invasive procedure than transplanting maskroms to another board.

    Gold star for Bratwurst! Or a jar of sauerkraut? Anyway, got this back out today, pulled the battery and it now works fine, other than not saving. Just need to order some tabbed batteries or maybe holders and it'll be ready to sell or trade.

    Excellent, thanks for getting back to us on the results. This pretty much verifies an issue anyone else might encounter down the road, especially considering the increasing age of those original batteries.
