I’m not sure if Neo-Geo machines got a mention in the final chapter of Arcadian or not, but I remember seeing them in arcade during my high school years. I also remember being aware of the home console. I never played either, but I was interested in them. I was particularly interested in the memory card feature. I don’t know how it actually worked, but I thought it allowed you to take the arcade game home with you. If that’s not how it worked, it is how it should have worked.
I remained interested enough in the Neo-Geo to watch this short doc on the rise and fall of SNK. If you were a Neo-Geo fan (or just a casual observer like me), check it out.
