Hi and officially welcome to RVG! Glad you joined the site! What happened to your 5200? I didn't get a 5200 until I was an adult. I like that it has games that are only available for it. RealSports Baseball on the 5200 is an amazing game! That's quite an impressive score for Pac-Man on the 5200! How long were you playing?!?
Those are all great 5200 titles. Did you know there's a Pac-Man Arcade homebrew release for the 5200? It is closer to the arcade in many respects. Might want to check it out.
