Fun fact:

The SNES and N64 still did that it was a fundamental flaw in exposing the chip on the cartridges.

Still a easier quick fix then repairing a scratch on your CD.

Nowadays mind games are becoming digital.

Sometimes, the cartridges just didn't sit right inside the slot. Tilting them slightly to reposition them sometimes worked. And it's really hard to get them to ork if some of the circuit board contacts have fallen off.
