It was even crazier in Japan and to this day I don't quite understand how their 90s- era "videogame sent over television" and "videogame sent over ancient cell network" features and dongles worked. I'm trying to remember the names of these features exactly but can't, I just know that it was like, the NES or SNES you could "download" games onto somehow from a TV signal, and then the GB or perhaps GBA had something similar if you connected your console to your phone.
