I couldn't really see the point in buying the mini NES and SNES
Assuming the people that did buy them are the Nintendo Fans that want any official product to add to their collection. for me I would much sooner have the flex ability of a Pi in a NES or SNES case so you can have all the games. 20 or 30 games like they put on them, I know I'll be bored in no time and it won't have the games you wanted
PC Engine in it's day was amazing, I didn't have one or any of my friends but remember them in one Video Game shop in town, I did get the emulator years back and tried some of the games out, was as close to arcade at home you could get
Previous arcade quality games on console to these were the Colecovision, they were amazing at the time too
Wow I didn't realise they were that small anyway, years since I saw them in the shop
If you don't have an original then these would be ok to own, but I would only bother if they made all the games available, they should bring these mini consoles out and at least allow streaming of all titles to add priced each, they would surely make more money that way, but then I guess with games being made by different companies they can't
So if Konami own Hudson, are you only going to see Konami games
Still sooner have original or wait till Retroflag case for Pi
