Some personal favourites:
-Battle City
[You are a tank shooting other tanks trying to defend what a appears to be an eagle from getting hit, with coop and a map editor]
-Paper Boy
[Deliver the newspapers to the correct houses avoiding dogs, cars and even death himself]
-Chip n Dale Rescue Rangers
[A platformer where you defeat enemies by picking boxes and throwing them, made by Capcom so expect some difficulty]
-Gun Nac
[A shooter where you Shoot everything that it moves, with pretty big power up system (I hope you like carrots)]
-Adventure of lolo / Eggerland series
[A puzzler where you have to get all the hearts and reach the chest before getting hit by monsters]
-The Flintstones: Rescue of Dino and Hoppy / Surprise at dinosaur peak
[Both made by Taito, Hit enemies with your club and reach the end of the stage (protip: hold a to hang from cliffs and then up reach upper platforms
That's all that i think of right now and i think they are pretty easy (IMO)
