Awesome videogame music (Before y2k)

Hey there derpiboorians. I was wondering, which are the songs you remember fondly from your childhood before year 2000?
 
It can be songs from any console/handheld/desktop device with games in it.
 
This thread can also be used to find that game you cant remember it’s name.

I will start with Battleship: Surface Thunder (Made by hasbro in 2000)
 
OST from Level 3 / Battleship Classic Mode

Reason why i like it: Its quite catchy.
