At first the NES version was supposed to be done with the help of Paul (InfiniteNesLives) but he's very, very, very (x100) busy so it was not possible for him to do it at the same time as the FC release. This caused some logistic issues and they are scrambling to figure out a way to get some NES version but there is no official release date yet (they are testing how to make NES cart at the moment). Since they are not sure how well it will go (making the carts), they will start with a small batch to test feasibility. As for reservation, unfortunately I don't think they have such system and only the BOOTH site will allow to buy the game. I can still ask if they can do any reservation but I cannot promise anything
The NES version should be mostly the same thing as the FC one so as long you have an adapter it should work. If I can have an idea how many people may want the NES version instead of FC one I can give them the numbers and that can help them for preparing the first batch.
The FC version release is not affected and should hopefully be released at the beginning of November.

The game is available in Japan since the beginning of the year (? March, April forgot the exact date) and can be bought at Akihabara or the Toranoana website. There may be other places that sell it but I'm not directly in contact with him but can ask questions if required.
