why do some old game carts have corrosion and rusting on the components of the PCB board even though they were well-kept and have never come into contact with water before?
i have a couple of old game carts from the early 1990s that have never been opened up before, i've decided to check on them and apparently the game carts now have alot of rusting developed inside of them. its not like the internal battery or capacitor has leaked all over the board or anything like that; those were fine as they are. And i've never dropped the game carts in water before or spilled anything on them. in other words, the game carts have always been kept in my old toy box cleanly and neatly for the past 20 years.
so my question is: Why did some of my old game carts corroded/rusted on the inside even though they were kept in good condition?

i think this photo depicts my problem more accurately, basically the metallic legs of the ROM chips have corroded on my game carts.
thanks for the help!
