By original release, I have Mystery House in a collection.
Actually oldest as version I have, that'd have to be one of my Master System games. Oldest seem to be from 1987 (as this European release): Hang-On, My Hero, Snail Maze, Great Golf and Marksman Shooting/Trap Shooting/Safari Hunt (3 game pack for light gun).
Ones that I've had longest are the build-in games in my Master System (from 1990): Hang-On, Safari Hunt and Snail Maze.
