Sadly, not anymore - TecToy lost the Sega license a few years ago. In the later years, they were simply rebranding AtGames plug-and-plays with the Atari and Sega licenses; and more recently, they did a half-assed attempt at launching a rebranded Ayn Loki in response to the handheld PC boom[0]. They don't do much in the gaming business anymore, instead focusing in the smart appliances and credit card readers for businesses.
