Rick came across a Game Boy Color that we have for some reason though I still don't know where it came from (I never saw it when I was a kid; I think my sister may have had it at some point?). Compared to a cell phone game or something though, I'm fine with him playing some sort of Mario game on it.
Somewhere in this house is my Atomic Purple GBC. I wish I knew where so I could let the kids use it. In the meantime, emulators exist.
Purple, you say? Hmm, maybe that's where this thing came from...
I didn't have any Mario games though. Link's Awakening, Pokémon Red and Gold, and a Castlevania game.
