And that's it! I ordered 10 units and tested a couple of them and everything seems to work fine both with SNES and NES Mini controllers (although the SNES Mini one requires some special boot sequence, so it needs to be plugged BEFORE powering up the device - yup, a firmware update is required to handle this via software, indeed).

And that's everything I have for this update! Let me know any question or suggestion you may have about the project! : D
