Exellent agapter!! Whish they sold this 20 years ago!
I am always hunting for original controllers for the nes, this days that is almoust impossible to find, when I saw rhe announce about this adapter, I had my doubts, always this kind of things doesnt work as they announce, after watching some review, they said this thing was very good, I decided to buy. Also I bought 8bitdo controllers with the nes design. This thing works very well.
The design of the adapter is similar to a plug of an original nes controller, very easy to plug. To pair the controller just press the pair button on the adaptor and on the 8bitdo controller press start 3 seconds to turn on, there are different modes on the controller I have not that much idea the different modes, but just by turning on it paired.
The button mapping was Y = b button, B = a button, X = b turbo, A = a turbo, L and R doesnt do nothing.
The feeling of the 8bitdo nes controller it feels like an oroginal nes controller, I tried with battletoads, it feels so natural, just in the turbo tunnels and 11 stage I had trouble, because so fast stages, it was slow I felt, but in plataform stages feels so natural!
About the control vbutton mapping, I am happy how they put it, I think it deppends on the firmware installed, I just received mine the 1st of August so I think i git a newer firmware.
Also tried wii mote, so easy to pair! Just like original wii! It works so nice, I am happy this give me so many control support, and I have so many spare controllers for my other consoles.
The only bad thing I can see about this is the official web page, it looks pretty, but so hard to find the correct information, I was trying to look for detail manual, but is not that much detailed, also to make new mapping of the buttons I think you have to use computer and do something to the firmware... I think... Also the firmware is so confusing, if I download the most new it carries all the updates of the other updates? Or each one has different and specific function? I feel so scared to update, I sont want yo break my adapter.
Anyway, I really recommend this thing, even if you dont have the 8bit controllers, there are big chances you have a wii mote, ps4, Wii u pro controller. So this is a must buy!!!
