For anyone not around during the late 90s; the above image might look like some sort of fever dream but this is an official Sony Product designed to enable internet access for the original PlayStation.
- Yes, this did get released!
- Yes, there are games that use it!
- No, it didn't leave Japan!
Maybe the most well known game to use it was iMode Mo Issyo:
A game that is not only an expansion pack for the Sony Mascot game; Doko Demo Issyo but also must be used in conjunction with the Japanese only Sony Pocket Station.
