MVS trace too corroded?

[shmupsrocks]

Is this MVS-1F trace too corroded to rely on if I replace the battery? What will I lose if that trace fails?

Multimeter is your friend

Any idea what a broken trace there would mean for functionality?

Looks like it’s just the battery circuit, so probably just the battery backup.

In any case I’d remove the old battery ASAP before it does any more damage. Mobo will still function

I should know this but battery backup is for high scores only?
