Summer Carnival 92 is a super rare and super expensive Famicom cart created by Naxat Soft for a video game competition.
It’s not the best shooter ever made, but it’s pretty damn good. It does things that simply shouldn’t be possible on the Famicom/NES. Seriously, I think someone sold their soul to the devil.
In the days of old it wouldn’t be unusual to see someone pay 600 dollars, before shipping, to own one of these. I personally paid 50 dollars for a reproduction.
You, dear reader, can get your hands on this strange work of alchemy and video game history for just 5 bucks from the 3DS eShop. Do it.
