How many of you have ever heard of the Kiddy Sun in Fantasia game? Basically, it is a hack of Adventure Island. You can watch the video of it here:https://www.youtube.com/watch?v=aiLaZSs5xbU
For the longest time, it has been debated as to whether the hack was officially licensed or just a bootleg of sorts, with scraps of information leaning both directions.
I have always suspected that the game was licensed from Hudson Soft, and is thus an official Famicom cartridge, and I have today confirmed this as fact. We should throw this one up in the database, now there is another licensed game variant for people to go nuts over, trying to find.
