It happens again throughout the story. The figure pictured here: https://i.imgur.com/M6YHU51.png misrepresents that also as a Genesis. No Master System in Brazil was a version of Genesis. The Master System revisions included the 6 button controllers but were still Master System consoles. Only played Master System games. Not Mega Drive games.
Every version of Genesis was called Mega Drive.
edit: Thanks for fixing it!
