That one is the Master System II. It’s the cheaper one from around 1990, after the 1989 Mega Drive (Genesis) was released.European Master Systems are bloody weird looking, but it's definitely stylish. Hardware is soooo much better than the NES as well.
The case design has been used even up to relatively recently in Brazil!! I was surprised that the SMS was still popular there.
The longer flat one was the first edition and based on the Japanese Sega Mark III.
I was trying to collect the varients at one point but even then the cost was pretty high. I’d hate to even tried collecting the NES/Famicom!!
I blame YouTubers and their nostalgia generating videos. Grrr.
