I've got the recent released N64 plug-in adaptor. I've tested it with Super Mario 64 and the original Nintendo 64 Controller so far. Both worked fine. Thanks a lot! :D

However, the Retrode refrains from recognizing my Hori Mini Pad N64. This is an officially licensed controller which was released in Japan near the end of the Nintendo 64 lifespan. It has an analog stick design similar to the GameCube controller and won't wear out. With the Retrode, no buttons and no stick of the Hori will be recognized. The Hori controller works fine on my original N64 video game console.
As far as I know, there are only a few N64 Controller to USB adaptors capable of supporting the Hori Mini Pad N64. This is an article about the compatibility issues:

One of the adaptors that are supposed to be compatible:

I would like to know if there'll be support for the Hori Mini Pad N64 in the near future? If no, I'll treat myself to one of those adaptors from Raphnet. :)
The N64 controller protocol and timing is rather hard to get right (it's the only part of the Retrode firmware I had to write in assembly). I'd need one of those controllers at hand to make it work.
Raphael provided some information about the Hori's controller signaling:

If this isn't enough information, I may be willing to borrow you one of my Hori controllers for a limited time. In case, please leave me a PM. :)
I'll look into it when I find the time.
