This is maybe a dump question but ...

 

How the cartridges keep data (the games) since Fairchild Channel F?

Mask Roms are an array of connections of all 1s which during production of the internal chip has locations etched away forming 0s with chemical or other processes

 

Programmable Roms are a different story as are flash memory technology

I suppose we could compare the merits (or problems) of mask ROM vs. other storage methods.

 

But the best storage policy is to have multiple copies in as many places as possible. Ironically that means piracy has saved many obscure games from oblivion.
