Is there corrosion on the board?

battery holder bad, check for wear or corrosion
Sometimes people don't notice how bad these 30 year old battery holders are. I've seen plenty of green corrosion, or even missing tabs. Any of that stuff might keep the settings from holding.
on your mpu board, what number do you see on the 7 segment display?
what voltage do you have at the + & - tabs on the mpu board, your battery holder?
what voltage do you have at pin 24 on the RAM?

You're going to get that message right after you change the batteries. But, if you went in and set the date, turned it off and back on again and are still getting the message, it could be a few things.
Dead battery or batteries
Batteries installed incorrectly
Corrosion on battery holder
Broken battery holder contact pads
Corrosion on traces under or below battery holder
Cracked solder joints from battery holder to board

Might also take a look at section 6.11.3. I had the diode fail open on me and had similar symptoms.
Quoted from Metzu:Nono its super clean
Post pictures and we'll be the judge of that. 
Quoted from Tuukka:Fish Tales is a WPC game, there is no 7-segment on MPU board. And the RAM is 6264, 28 pin, so battery voltage can be checked between pins 14 (-) and 28 (+).
Thanks for correcting me and my apologies to all those that I mislead.
