What exactly is this caused by and is there a fix for it?
I can't seem to find much background on it and I have a PCB with it...
Thanks!

Flip the switch to have it erase scores on power up (SW2, #5 on) then flip it back. (SW2, #5 off)
You'll want to change the battery that saves them.

Did you have to replace the battery to cure the issue, I guess it would come back on every boot without a battery, but did flipping the dip back and forth cure it?
You wouldn't happen to know which SRAM stores this info, there are a couple of what are probably 6116 SRAM chips near to where the battery was once located but have had all their markings ground off. If they are 6116s then I would have thought their capacity would be hugely overkill for keeping a few bytes of highscore info.
I have 50 CR-2032 battery holders coming... should be here in a few business days from California. I also have a T&F boardset here that I parted out to save a Hyper Sports and I can check to see if they fit properly.
You can also get coin cells at Batteries Plus and they'll spot weld the solder legs for free to batteries they sell. You might check to see if they have one of those in your area.
