Popular in the UK and Brazil, I never knew anyone who had one here in Greece. What are some of your favorite games and memories from it? It could be any iteration of the console.
You can play it in a browser, I can recommend Wonder Boy 3: The Dragon's Trap (also its excellent remake on Steam/GOG is worth it): https://archive.org/details/segasms_Wonder_Boy_III_1989_Sega
