The Retron is back! Hyperkin's follow-up to the Retron3 now expands its compatibility up to 7 consoles. Powered by Android, the Retron now has HD output, interpolated sound and save states! Wait, what? Seven? But it says "5" right there on the box? Well, with a pass-through adapter it's actually possible to play Master System games on this machine. So to sum it up: It plays NES/Famicom, SNES/Super Famicom, Mega Drive, Master System, Game Boy, Game Boy Color and Game Boy Advance. Have fun.
