not sure what you mean there, sarcasm?
anyway there are generally two cases 1. it's just a static dust problem, clean the connections and you're good 2. a pin is badly damaged, then you need to desolder it
but I have yet to see a single mask rom chip which got corrupted internally, the chemicals are very stable and well protected, unless exposed to sever heat or to eternity of time, then it really hard to corrupt them
