You mean a ROM cartridge as opposed to a magnetic tape cartridge, right? ("Cart" is also broadcast radio slang for magnetic tape cartridges, vaguely like an 8-track tape in appearance.)

That would depend on the ROM type: mask, PROM, EEPROM. I don't know which was used. Fuse PROM supposedly may suffer from "fuse regrowth" depending on manufacturer and process used. But if well made I would expect them to last as long as any other solid state electronics.

Placebo effect? :-) I can't see how it makes any difference, unless the contacts are dirty. If they are, they should be cleaned, with a proper cleaning method.
