I have a few weeks ago ordered me the adapter together with the matching "original" SNES controller.
I use a SNES emulator with a Windows 7 64bit operating system and everything runs smoothly.
The adapter makes a robust impression and a reasonable cable length of about 0.5m.
All in all I am very happy and can now relive on my PC agree my fondest childhood memories again :).
Therefore, from me a clear Kaufemphelung for all pixels nostalgics.
I hope my review was you / help you.
Cheers
Marian
